Re: Tune-port install
Alright, so I've been debating and would I benefit if I bought some after market aluminum heads would that help with the engine falling off at the top? Also what cam would compliment this idea?

Re: Tune-port install
Your best bet it to call Comp Cams and give them the specs of your engine, estimated vehicle weight, gear ratio and tire size and they will pick the best cam for your application...

Re: Tune-port install
Thanks, problem is I'm not sure how I want to go, whether I want to run stock cam and vortec heads, or after market cam, aluminum heads. See my prob.?

Re: Tune-port install
Your problem with falling off at the top is caused by the intake. If you want to solve that problem get an aftermarket TPI intake.
I had a TPI on one of my trucks, and the truth is, I didn't drive it at high RPM's so the lower end power is what I really wanted, and that is what the stock TPI provides.

I have a TPI engine out of a 90 Corvette hanging on an engine stand in my garage. It is an L98 engine and it came with a set of aluminum heads. These are the same heads that the ZZ$ engines have and that design was good for about 4000 RPM. I got the whole deal in parts and the engine was already seperated from the intake and the intake had been refurbished by Street And Performance of Arkansas. The engine has changed some since my purchase. It now has a set of vortec heads that have been worked to take a different set of valves and the seats have been clearanced to allow for more rocker arm movement. The cam is still the stock roller unit from the Corvette but I changed the rocker arms over to a set of Comp Cams magnum 1.6 roller rockers. This gives a better flow without changing the cam. I put an intake baseplate from Scoggin dickey for the vortec engine on with the larger runners from Edelbrock for airflow and th einjectors have been upgraded to a large size. This should provide a fair change in flow and give some serious low end torque. Presedntly this engine is set up for my daily driver 91 Chevy truck as a replacement engine for the factory 5.7, but it will fit anywhere, since the computer is set for a streetrod install. |

Re: Tune-port install
i got a camaro with a zz4 355, and edelbrock heads, now when i thought about intake there's gm tpi.... but better than that, holley stealth ram, or edelbrock pro flo. either would be a better choice than the gm stuff. i got the stealth ram and it's much easier to install and tune. comes with fuel pump/filter, computer, harness, intake, runners, plenum, and the other goodies. its around $1200 to start with either edelbrock or holley and more worthwhile
