Wes, have the numbers for the two heads?


You are saying that the smaller head albeit flowed real well drove better had more response and ran a little quicker?
Gee, another person this seemed to work for. lol

Keep up the hard work.

On another note wes, any insight as to what the HP numbers were on each?

jsup, I never had either engine on a dyno... engine dyno or chassis dyno. I suspect both are in the 380 - 400 HP range, with the Dart combo making more avg torque, and the Camel Humps making ore peak HP.

The 327 may be going on a dyno soon, but I just do not have the time or $$$ to spend on the truck engine.

In the past month and a half, I've done the following, without quitting my job (in chronological order):
1. Coached my sons soccer team
2. Swapped 1 5/8" headers for 1 3/4" Super comps
3. Raced at Famoso on 10/19
4. 2 supplier audits in Mexico
5. Swapped fom a dual plane to the Team G on the old 327
6. Went back to Famoso on 10/25 and 26 with the single plane intake
7. Pulled the 327
8. Did an in-car cam swap on my friend's 1965 L79 Vette
9. Tuned a 69 Camaro SS and a numbers matching 66 L72 Vette
10. Reported to MEPS for a physical (might be going back on active duty)
11. Assembled and re-installed the truck engine (this was its second time in the 62)
12. Went back to Famoso

As I sit here typing this, the wife is asking me how I did the above, yet manage to ignore a leaking shower head for the past two months.

I dunno, that kinda stuff is way above my pay grade.

The results of the cam/head swap were an improvement of .15 seconds in the 1/4 mile, and 0 mph compared to the old dual plane/solid flat tappet combo. The car went a best of 12.64, versus a previous best of 12.79 with the old solid flat tappet/dual plane combo.

I played with both the timing and the jetting one change at a time to reach the results as shown.

Not a bad increase for the cash outlay, huh?

I'm not sure, but I think you went from some old camel backs to Darts and from a solid flat tappet .520/520 232/232 to hyd roller 222/232 ? Do you feel like you have more rpm to work with now ?

What were your 60's ? And I assume your mph was 107 mph, thus your 1/8th must have been around 84 give or take a mph ?

In any regards, I agree, I wouldn't really be happy with those results, particularily your trap speed.... I would have predicted a 3-4 mph pick-up.... but I'm not sure considering I do not know much about those old camel backs you had and how good they are.

I don't know, I'm trying to read this right from his original post, but it looks like he went from an original 327 to a new combo with a 350 block, but a 3.75" crank, thus he has a 383, plus he added the Dart cylinder heads and hyd roller cam, which with his 1.6 rr on the intake and 1.5 on the exhaust was a .524/.501 223/232 @ .050".... from an old solid flat tappet grind that would have .520/.520 with a 1.6 rr, and 232/232 @ .050"..... not sure if he was running a 1.6rr, doesn't say, which would change the specs to .487/.487 based upon his .325 lobe. (The new lobe is just a .328)

Both set-ups used the un-named low profile dual plane intake. Which probably does hurt power, but just speculating, I know nothing about it.

If this motor is a 383 and the above is correct, I would definitely be disappointed, even with a restrictive intake, you should be up and above 110 mph with that set-up..... I say this only because, I have run over 110 mph with a bone stock tpi plenum/runners/manifold combination before, thus I'm thinking regardless of how restrictive that intake is, he should still be able to get 110 out of it.

In my opinion, your converter is fine for that set-up, although it would run quicker a little looser.... you're still fine.

But, maybe I'm reading the original post in-correctly....

2. My combo is restricted as to what intake it can run due to hood clearance issues. An RPM Air Gap, or a Stealth Airstrike would have been worth 1-2 MPH, even with the less than ideal shift points. The C3B intake is probably older than I am. It defintely wasn't an asset, it's like a Performer, but 2 generations older.

I also just noticed, he has an original 327 sbc block, bored .040" over with a 3.85" stroke...... this indicates the original motor was along the lines of a 396..... considering I believe the original 327's used a standard 4.00" bore, with a 3.25" stroke.....

Thus going from a 396 to a 383 ? Am I reading that correct ?

BeachBum wrote:
Well, if we're reading it correctly, yeah it changes, both the old and new set-up was not running to its potential.

But, on the intake, fairly common problem, I know edelbrock has several different low-rise intakes to chose from..... don't know if any will fit his application, but certainly worth a look into it.

I'll tell you what though, finding power is what this hobby is all about..... start tinkering and you'll find it. My first time out with my old 383 set-up, I ran 12.2 @ 110 mph.... I was pissed. Took it home, put it in the garage, found a few problems and tinkered with it a bit, the very next weekend it easily ran into the 11's.....just slowly widdled it a down after that through experimentation..... was fun getting a new best almost every weekend for the first few months of dialing it in. I recommend it for everybody.

From the other post, it looks like he just pulled out an original numbers matching 327..... thus, I'm thinking his 3.85" stroke in the first post in this thread was a typo mistake ?.......

Makes a big difference on expectations....

Beachbum, I don't recall the guy's name, but his car had later "disco Vette" body panels on it. He used to run at the WCCC events. I want to say it was a darker color. He used to trailer his car in.
