The full potential of the test? The test is done. The AFR's got the same treatment the TFS heads did. To compare numbers I may (or may not) achieve down the road gives the AFR heads an unfair advantage.

The car is for sale, $12,500. Black on black, 82000 miles, new motor, AFR heads, Centerforce clutch, Summers Brothers axles, etc...

I'm just burned out on the car. Time to move on.

It's been great following your testing. Thank you for that.

Just don't go buy a dodge, ok?

C4's will do that to you. I know how you feel.

Thanks for investing all the time and money into performing the tests. Your documentation will live on for years.

Good luck on the next project. I suggest something with a solid rear axle, that won't cost $500+ every time a screw breaks.

Very true. It seems like the AFR's out performed the TFS heads, but by a slim margin.


It sounds like someone will be getting a deal on the car.

solid axle is great for 1/4 mile, but it's nice to corner and brake.

i second what joe says. even though josh and i dont see eye to eye (well he is 5"6), i thank him for doing all of this testing. sooner or later, we will see what the exact same AFR heads josh used with 38 more cubes. i just have to get my ass in gear and finish it up.

i hear what your saying. before jim started the 421, i was thinking about selling it, and buying a 04 Z06. but then i thought long and hard, and i would of had to mod the C5 as well.

after i am done all of this work and invested alot of cash into my 88, it wouldnt make sense selling it, plus i simple love this car.

glad u kept it. i enjoy reading your threads.

I had to re-finance the car for the testing, so making payments and carrying full coverage insurance on the car while it just sits in the garage isn't my idea of a good time. I've already got a ton of money and time tied up in the car, and I've gotten virtually no return from it. Letting it sit is just going to add cost to a car that already had a really poor dollar/fun ratio.

Thanks for the compliments on the testing/documentation.

Not sure about the next project. I think I'm just going to take some time off for awhile. I won't be able to stay away for long, but for the time being I'm tired of it. Maybe a C5, or an LS1 F-body sometime down the road.

Josh, you're going to regret it long term if you sell your car before you've seen it to its full potential. You need to get it dialed in and hit it with a 200 shot and run a 10.50. Then the 300 pills and run a 9.90. You won't be burned out on it then!

I've had the C5 bug lately, but I'd probably hate myself if I got rid of the C4.

I want to sell mine twice a year. I keep it though as I have no desire to lose a ton of cash. Ya never know Aliens could steal every Corvette leaving mine as the only one left. Then I'll make big bucks LOL


GOOD LUCK with whatever you decide to do.

Mine has frustrated me to no end. Its in our genes to perfect these things. C4's are kinda challenging when there are superior vehicles out there, especially cost/dollar. But, drink a few, let it set ( you only need comp and collision if it is not being driven)

It seems to me the reason C4's are so cheap AT THIS POINT IN TIME is that it's owners are willing to let them go so cheap. For what they can GET for their vette today. Sure, we all understand the value/cost thing and so do the people with the cash. But look at Corvette history....in 5, 10, 15 years from now? When a ROUGH '86 AT is a STEAL at 10 g's and an LT4 (in any condition) is 25 G min......don't even ASK me to guess at the GS value in 15 years!

Do I need to remind you all of the restored 283/4 rag '64 at 3K? Or the rough '61 at 1,500 (in the mid 70's)? The trailer '56 (complete w/all chrome) FOR 1k in the early '70's. The really clean '78 for 4K and the average '80 for 3K in the late 80's? The tons of 'rough' C3's in the late '80's/early '90's that could be had for under a grand each? ~These are all vettes I persued throughout MY life~

The Corvette demands more appreciation! And it always comes back to 'center", doesn't it? At one time the C1 was considered total crap, wasn't it? At the time NO ONE with any sense would think of a C1 EVER being worth 1/100th of what they're worth in the future.

EVERY corvette ever made EVENTUALLY reaches to GREATNESS.

Josh, you are "The Man" among men for doing this swap just for results sake. I applaud you for it! However, my personal view on selling your car right now is.....not to. Give it a little time. I was burnt out with my little mess a while back, got away from it for a while and now I'm right back in the thick of things doing a cam swap and enjoying the hell out it. You can always sell it down the road in a few months if you still feel you need to. Think about it....what can you replace all that time and effort with and most of all the self satisfaction the car has given you. The last part would be important to me. I can say "I did that". We're all different though so good luck and enjoy yourself whatever you do and thanks again for all of your hard work!!!

Just my $.02.

Agreed. Some of the reasons I bought a C4 was because I figured it was like a 3rd gen fbody that could take a corner. I was convinced between the IRS and the rack + pinion steering it would out handle the WS6 cars I owned previously.

And it does.

Unfortunately, that is about it. Perhaps for a 5'4, 130lbs driver it's a nice car. The fall in, climb out sucked. Between that, the ergonomics of the interior, it made for sort of a crappy driving experience. Oh and when I went to a stick, it was kinda tough with big feet. (size 13).

My cousins '90, (A4, modern interior) is like a jet fighter. Still have the fall in, climb out aspect but the interior is at least nice to look at.

No, absolutely not.

About the only racecars on a roadcourse with a solid axle are Nascars and they handel like pigs under braking and in the corners.

Eh, then you need a cage to run 13s in the 1/4..


A vert would be nice for a summer daily driver.

I sure wish someone made a bolt in cage, something that could be removed, then bolted back in for track days, then unbolted again. Maybe something that requires and hour or so to remove or install. I'd buy one.

Just can't picture driving down the road with the top down on a hot summer day with the wifey's hair blowing out through a big ugly roll cage!

The S/T Frame from RD racing does bolt in and out. You need to cut a few things for the coupe.
DRM makes/made a convertible roll bar you can still use the rag top with and it was a bolt in.

Will it pass tech?

I was under the impression the book was pretty strict about cage installation, mount points, etc.

I'm just not interested in caged cars. Call me a wimp, but I'd rather run 11s at a high MPH and be traction limitted, than have to crawl my fat ass in and out of the car like a jungle gym.

Its not like that at all, the cage main hoop is behind the driver, only way that gets in the way is if you're climbing into the driver seat through the hatch. With the door bar, most run a swing-out bar their that opens with the door, or not even run it all....most tracks don't look for it. I bring my side bar to the track with me, but it typically stays in my pit.

All you need to run to 9.99 by NHRA rules is a 5 pt bar, thus you do not need the passenger bar.

I thought the rollbar would be a pain in the butt before I got one..... now I know better.

It did here in Hawaii, NHRA track. It is/was a two point, and no one questioned it. It doesnt have a door bar, which isnt hard to add IMHO.
