Exactly, that is why you need a dual plane manifold and mild gears. No more than 3.55, and radical cams only steal low end power.

I did not argue with you about the dual plane manifold. The performer rpm is a great manifold thats what I would recommend but at the time the car was built I was describing that manifold did not exist and the performer was exactly like a stock intake. Look at the ram air IV cam pontiacs react well to long duration. if you run a cam with a short duration you just increase the already abundant low end torque of the engine and do nothing to help the mid range power. Then you end up with a car that will not hook up and when it does it is already past its powerband.

yah so I will run the same came as your friend exept I will use a preformer RPM cam

which should only increase torque

You mean performer INTAKE right? edelbrock cams suck, thats the only thing i've ever seen that they suck at. Otherwise, edelbrock is good.

yeah intake not cam I was typing fast.

o crap I ment the intake too their cams do suck

edelbrocks carbs arent the greatest either and their headers kinda suck as well other then that they are a good company

which do you think is better a preformer RPM air gap intake or just the regular preformer RPM

is it worth the price difference?

I don't think they make the air-gap for pontiacs do they?
If they do then get it, providing that it can fit underneath your hood! I don't think it will, I've seen one on a small block chevy and it was very tall. It probably won't work on a car.

well I am planning on putting a 4 inch cowl or so on my car so im guessing that the air gap will fit underneath the hood even with a tall air cleaner

I don't think there is an air gap for pontiac. there would be no point pontiacs have a seperate valley pan so there is already a gap under the intake.

petereggy · #56 08-11-2003, 01:56 AM

yah I have looked and I havent found an air gap manifold for pontiac but o well im sure the preformer RPM will do just fine

TorinoGT69 · #57 08-11-2003, 01:57 AM

it should fit no problem if you have a 4inch cowl .

petereggy · #58 08-11-2003, 01:58 AM

yah I think I will have lots of clearance under a 4 inch cowl but I will still wanna try and fit everything underneath the stock hood because the cowl will be one of the last things I buy

TorinoGT69 · #59 08-11-2003, 01:59 AM

do you have a shaker hood or flat or formula type?

petereggy · #60 08-11-2003, 02:00 AM

with a built up 400 do you think I will need to run an after market distrubuter?

or could i get away with running a msd ingnition pack whch has a coil, the 6A box and a couple other things
