I can tell you that with those heads, you should see more low end powa with a 4150 and a carb hat. I've tried both and found that turning air between the plenun and tb netted less hp on N/A. I grabbed 22hp and wicked throttle response with the accufab 4150 and a 1/2" plate. If I could fit more plate (add plenum) i would probably see more but then ya need to loose the stock hood and I dont really want to change the hood. Might try lowering the k member though.

If I were you I'd add front drag shocks to make the 325's work. You have to keep the nose up and keep the weight on the dr's, or it will unload and wheel hop, or just spin. I'd consider the QA1 R shocks since they won't bounce when you launch and will keep the nose up.

I stated earlier about wanting to see this combo with a 4 hole TB on it.
Also on the shocks, here is my experience. When my first car first got running I had problems getting it to hook. I had wheel hop issues with the 325, BAD issues that day. I have Koni DA's on the rear and started tightening up compression on the shocks it got better and better. When I got the wheel hop gone I started tightening up the front shocks until 60ft fell off. On a good track I can run the front Hal SA's on 6(in the middle) that setup generated the 1.43 with a converter thats too small.
If you want to shoot that much spray to that weight car you NEED double adjustable rear shocks IMO. You wheel hop that bitch on a 300 shot and your fillings are gonna be loose. WHeelhop is VERY hard on drivetrain parts.

+10 on the shocks, though those who have lowing or progressive springs need to bewary of the shocks travelling out which will probably negate the shock all together. It doesnt appear that he has lowered it in the pics. Stock rear springs seem to be just right. also control arms need to be right as well. DA Afcos all around and Ive never experienced wheel hop.

Not trying to defend either car or knock either car but you have a higher MPH NA in the 1/8 mile because you have a car that weighs 190 lbs. lighter.
I will say the both of you are making me feel real good about the way my car is performing being only a 346 CI engine and on 26 inch tires to boot! My car is always at the 100 MPH mark in the 1/8 NA.
Anyway I hope you get it figured out WizeAss! Sometimes it just takes time. For what it is worth I would have put the front shocks on first before I ever even changed out the back shocks. I have been many 1.4 sixty foot times with the stock shocks on the back.
Good Luck!

N2, just curious what your car weighs? Either way you have that thing running really good for a 346. My engine/ gear/ converter is setup for N20, so its NA times aren't very impressive. I plan on putting my car on a diet over the winter, and hopefully it will be close to 3100lbs. when I take it out of storage. Anyways, Wizeass, keep me updated on how your car runs on the N20. I have yet to spray my car but if my car responds to the bottle like yours does, I will be very happy.

John, I tried to send you a PM. I was trying not to hi-jack the thread but you do not receive them. So here are your answers.
Comp Cam special grind less than 610 lift and has less than 230 duration. The engine is real street friendly and has about 8K miles on it and just a little over 200 passes down the dragstrip.
I shift at 6,400 1-2 and 6,800 2-3.
As stated before I feel good about how the car is doing, it has been a lot of hard work.
