Tune Port Mod

Paladin62 · 04-24-2008, 03:28 PM

I have a 73 T-Top with a 350. It has a Quadrajet on it. I would like to modify it and install a Tune Port system.

I understand it is doable but I need to find the correct Tune Port manifold to bolt to my heads. So. What years should I be looking for to get the correct bolt pattern?

Thanks

All Corvette TPI manifolds will bolt to your heads, but don't do it. As great an idea EFI is, the time and money you spend converting to the factory TPI will produce a major disappointment, if you are looking for high performance. The Chevy TPI intake is quite restricted. It is rpm limited and runs out of breath before 5000 rpms. Unless you are just looking for the smoothness, good starting, and fuel mileage of EFI, you will be much better off with one of the stand alone "systems" offered by Edelbrock, Holley, and others.

RACE ON!!!
