G 8)

wow novaman, that is about the same as my block but im using a
hogan intake EFI same trans but my roller cam is 636 lift max.
and it's going in a 72 nova, you must be my brother from another
mother, welcome brother novaman, :wink:

I would lose the Team G for a 454-R

these are both good manifolds...est hp 600+...I would like to see more compression in it with those intake and big carbs...maybe 11:1 or 12:1

I'd lose them pro-comp heads too.

650Hp max - your losing alot trying to suck air thru a straw, you need at least a 1050 dominator.

THANKS FOR THE RESPONSE, I CANT FIND MUCH DIFFERENCE IN THE TEAM G INTAKE AND THE 454-R... ALSO WHAT WOULD MAKE A DART OR OTHER HEADS GIVE ME AN ADVANTAGE COMPARED TO THE ALUMINUM PRO-COMP 320'S?.. THIS IS STREET DRIVEN QUITE ALOT, SO I WANTED THIS TO RUN ON PUMP GAS.. WILL A 200 OR 300 SHOT OF NOS MAKE UP FOR THE LOWER COMPRESSION?? SIGNSBYESA YOU HAVE GOOD TASTE BROTHER, MINE IS IN A 62 NOVA, NOVAS RULE! LOL HOPING TO RUN IN THE TENS THIS YEAR!!!

625 ish compression a little low, i would go with 454 r, and no less than 950 carb, 200 to 300 shot, of giggle gas will make up for a lot of short coming's :) . jmo

not on average .. 454R is a much better intake

...David I had both on mine...very little difference I thought...maybe more top end with 454R....

Not that pro-comp heads arent good flowing heads, I'm sure them 320's do - its their quality that concerns me.
The decks are thin as paper and the core shift is unreal, ask around they dont have a good repore here.
I know they were affordable, probably why you got them in the first place and I dont blame ya a bit for that brother man, believe me I know how it is, cutting corners is something I'm very good at.

You've already got them so I suppose your stuck with them now, I wish you the best with them, I hope you dont have a lick of trouble, maybe you won't>? its pretty much a crap shoot it seems, one set is good, another junk.

Again all this is> JMO
Goodluck, Cp

power guess and intakes
 

There was a PHR story by Vizard about 4 months back. His 492 street motor made 656 hp on a street roller. He made a big deal about having to get the lobe seperation angle right.
I also heard that Vizard had tested the Darran Morgan intake and found 20 top end hp on a motor of about 600 hp over what was supposedly the best of the rest??

Just over 2 tenths on mine :wink: I had VERY good heads on a smaller ci motor so that would be part of it, and the light car may help also. seen 3-4 others come up with a tenth or more also.

ive only "heard" the team g manifold being a so-so intake, if it was mine id put a victor on it. id guess 625 or so hp but the torque will be fun!!!
