Fuel pressure drop problem is where I would look. Either sticky injector, of bad fuel regulator is my vote.Diagnosis is in order.Clamp the fuel lines test, will tell you alot. Obviously pressure line clamp only, than clamp return line only. If memory serves right, and pressure holds when return is clamped, FPR is culprit. Check Manual, has test in it. Also could pull the rails, and energize pressure and check for leaky injector.

Problem more on a cold start???/

recieved the postal money orders today, so it is SOLD.

I tried a coule of air cargo depots, it must be some gov't law that you are a licensed shipper???? This is new to me.

I was going to convert my 4+3 to this, YES everything is here to convert, except a thow out bearing (release bearing)
I am even including the correct speedo gear for the 4+3 factory gear ratio 3.07, however the zf6 factory original car gear ratio (3.45) is in the tranny currently.

Believe me, it is killing me to sell this, but I need the money.

Item is SOLD, THANKS GURU

I agree with CC, 24 * with advance included, I was not figuring in the mechanical advance. I was doing the old school Method, hell I can throw the advance light on, I already know @ 2000rpm 's I am getting almost a full 38* degrees TOTAL TIMING. Tomorrow, I will throw the advance light on it, report my findings. Pretty bad over the weekend, I smoked a mustang with my plowtruck, up to 60 miles an hour, of course he would of had me beyond that, but I was in 4 wheel drive, and he could not man up to it 93 mustang being beat once, so I did it 3 times. anyways, I can tell you though I had a horrible loss of torque before I used the power tune method. My engine did not like anything beyond 16* initial NONADVANCED TIMING. sounded like garbage, and was not running right. Trust me you will know when you go too much advance, the problem is, carbs dont have a knock sensor to retard the timing, even when the inaudible knock does happen. I always error on the side of safety here.

i am tossed between 10* and 12* initial. If your going to 24* initial AT IDLE SPEED, vacuum advance unplugged and carb ported vacuum port plugged, and your engine restarts normally, something is wrong, your balancer timing orientation is off!

ported vacuum source on a holley is designed for a "lean cruise" if you can understand that. Meaning, weak at idle, strong at cruise, and weak at WOT. This is so for fuel mileage along with performance. At hoghway speeds 45* + in timing is not that uncommon, with light load. i ALWAYS USE THIS PORT. Oh and by the way, they do make a 7.5" power valve.

Now I would highly recommend a cheap Mr.Gasket distributor recurve kit. I used offset color springs, however I can not recall whitch colors I ended up with, along with what offset in stops.
. Also my base start with vacuum canister was as follows,however only really start playing with this after you get WOT in the pall bark, I completely turned counter-clockwise, than went 4 full turns in. I DID THIS ADJUSTEMENT PRIOR TO PLAYING WITH SPRINGS, THIS WAS THE FIRST ADJUSTMENT ON dIZZY I DID DO. I tried there, THAN SCREWED WITH THE WEIGHTS.

And after 2 weeks of tuning, after countless times removing cap, and other trial and error, I may off went like approximately and additional 1.5 turns on the vacuum advance. this is were I am at, again this was for my snowplow truck. with that engine, th400, 4.56 gears and 36" tall tires. Call it what you will with that cam, I expected a dog till 3000 rpns with torque, however, after tuning I am now pleased.

with 15 inches of vacuum would not a 7.5 powervalve be better? my rule of thumb was, 1/2 of idle vacuum.

Also, does your distributor have vacuum advance? I assume, can you adjust your vacuum advance, by inserting a 3/32 hex wrench in the vacuum tube fitting? Its been about 10 years till 2 weeks ago since I tuned a carb, however I always did the power tune method. I use to advance it till ping than retard it. I use to start with dizzy weights, and finished with the vacuum advance.

Just went through this pain in my plow truck, 10-1 355 sbc way over cammed 292 comp cam. took 2 weeks after work to get it right, included 3 carbs, and finally rebuilding the originally carb. I feel your pain. I did find 10* initial was the sweet spot also.

In part i absolutely agree with your post. However, I am adding an attatchment of a screenshot, form another forum , on March, 2007. This is a response to a post, with an individual, with a similiar problem as mine. Please note the response to the quote. I think this speak volumes, on the case, the MFG was quite well aware of a problem, And they do not care about the consumer. Instead, my interpetation is, come and purchase another set of our newly redesigned, hoping not to have any more problem product.
I bought a set of new cylinder heads, used for 2500 miles, and people are treating this like an 1100 dollar set of spark plugs. Hey try a new set of plugs.

No matter what would of happened,I would notbe able to port these heads. The porting shop, waived the 600.00 fee, obviously. The PORTING SHOP than got me a reasonable comparing head, for a killer deal.
My castings were flawed, since they were manufactured. This was common, after I did some research. I did get one hole repaired, however The other hole, is in a spot were only jb weld could be applied. No angle for a tig welder, I am a certified, mig / tig welder, trust me , if there was any chance, I would do it. Same fixture, machine, and program, produced many, many good heads, the water jackets, being shifted was a notorious problem, 3 years ago. One would be amazed, how many bad sets of heads are out there. I have read at least 5 others, with the same problem. I mean, I think, since the castings were acknowledged, to have been problematic, by there own customer service reps, there should be something for the consumer here. Heck, I would settle for a good discount. I think there action of correcting the manufacturing problem, than there lack of action of correcting the consumer that had the defective products, would hurt there sells. however, I guess, with as many of bad heads out there, of this design, this company would of went belly-up, and never released , by there definition, "holy grail" eliminator series.
by the way,the last I checked, I still had a function account over there, FOR NOW.

lord nows, I am in a similar fight with another head manufacturer, also.

long story short, I bought a new a*r 195 set of heads, and used them 2 months, I put on about 2500 miles. Winter came, I decided i wanted to upgrade from a 355 to a 406 short block. I took my like new A*R heads, to a highly respected shop ( Kippley Engines), I set up a cnc port n polish. well long story short I had a couple of swiss cheese spots in my runners, from the "core shift" that was common with these heads. That same cnc program later has run 10+ same cylinder geads without a hiccup, and they must of ran 30 + prior to my set of heads. You know a cnc is going to the exact same spot, every time. This was all prior to the holy grail of the "el*m*nator". Now i contact A*R numerous times, and they stated"aware of problem, and problem has been corrected" , however my problem is my own fault. I than last week asked a A*R engineer about my Dilema, and here was his response "

"That's kinda what I thought went down from reading a little of what you posted.

Consider this.....what if the place your head broke thru was always say .040 thick on most of the other castings....none of them would break thru but ALL of them would be extremely thin and long term reliability would always be an issue.

We guarantee our heads with our CNC work because we go thru all the extra trouble to cut our heads like a loaf of bread and make sure we have plenty of aluminum around our port walls based on the shape we CNC into the head (the water jackets are designed around our port designs....not someone else's)

AFR can not be responsible for another shops CNC program that obviously removes alot more material than we do in certain areas. It was up to them to do all the behind the scenes homework that we have invested in our own program (concerning verifying proper wall thickness) and they should have stepped up to the plate and offered you another one of their CNC castings in the event they couldn't weld/repair the one THEIR program broke thru.

That's what we would have done had you purchased our CNC program and had a problem with a port breaking thru into water. You should vent your frustration to the shop that did the CNC work.

How can you reasonably expect us to guarantee someone else's porting work....its no different than if someone buys our heads and grinds on them by hand poking a hole thru one of the ports. In that same situation would you expect AFR to eat the cost of a head and all the machine work involved?? Then think for a minute whats really different in your situation....just because they CNC'ed the same program before doesn't mean it was always right and the bottom line is with most products that you purchase, both performance related and anything else for that matter....if you modify it and have a problem you own it. You relinquish the right to return or warranty it....especially if what you modified created the problem.

What I would be willing to do just to try and help is to see if I can fix it for you and charge you a nominal fee to do so (basically do the work at cost). Perhaps we can repair them but of course I cant make you any promises.

Honestly though, the real company that needs to step up here is the company that did the CNC work. If you conducted a poll and shared this situation with everyone, I bet 75% plus would agree with what I'm saying....maybe more.

We are a stand up company and will warranty anything that we feel is remotely our fault....even gray area's that occasionally come up we stand behind, but this clearly is not a warranty with our company....the real warranty lies with the company that you paid to port your heads. I hope one day you step back and can see and understand that more clearly.

I would like to see if we can fix the heads....contact me next week if your interested in pursuing that.

Thanks,
Tony

I bought heads from Nickerson Engines BRAND NEW. ran heads for UNDER 2500 miles on a stout 355, than over winter, got a deal on a 406 short block, had headS cnc ported, SAME PROGRAM USED ON 30 + SETS OF AFR HEADS. went through on 2 water jackets, 1 hole is unrepairable,. Tony you know bout cnc machines, they go same place, same time, rest assured cnc machine was not crashed, not wrong with program either, did at least 10 sets afterwards, no problems. HOWEVER 2 MONTHS PRIOR, Kippley has a similar problem, core shift. I not trying to be an ahole here, however my money is as green as yours, and having 1100.00 in a set of heads that are junk, really pisses me off. I have the email responses, and was in contact with sustomer service. WILL NOT ACCEPT A RETURN!!! how is this fair to me?

The only thing I know about this situation is from what I have briefly read (and Im a little gray on this) which involves the fact this customer modified our castings by having someone else port them (and I believe broke into a water jacket which he now blames us for). This type of work obviously nullifies any warranty AFR can offer which would be standard procedure for anybody's product (if I buy a Dart block and grind and modify it to the point it creates a problem I wouldn't expect Dart to warranty to the block because it was my fault for modifying it in the first place....just an example of the point I am making)

That said I would like to hear the specific details of what actually went down and I encourage thic customer to contact me directly. I would like to try and work something out in an attempt to make peace but without knowing exactly what Im dealing with its hard to say what AFR may or may not be willing to do to help out.

My phone is 661-705-8508 or a PM would also be fine but I prefer we speak on the phone at this point.

Thanks,
Tony

I have a set of 2 month od, at the time) core-shifted afr heads ( common problem), that when I contacted customer service @ AFR, I was advised, " AFR was stopping flawed castings from reaching the consumer" . however AFR was not doing anything for the consumer, whom already has this product, whom lost 1100.00?????? every time I talk with Tony, I am ignored, just enhances my point further, dont you think???z well let me know, however I am not looking for a suspension or ban, however I want to share my $1,100+experience!!!!!
