Turbo street 400 build up.
Ok, heres the deal, I have been thinking this over for a long time but am wanting on opinons from everyone here on this turbo street car I am building.
I have a 76 T/A with T-tops. I added sub-frame connectors and sumped the tank with 1/2" line running to the front.
It is a 4sp car that I put a th400 in, but I AM going back to a stick for the street. Looking at getting a TKO 600.
I have 3.73 gears in the rear.
Was thinking about using an early 400 .030
Comtec .051 head gasket
SRP or alike piston
stock 3.75 stroke crank to help the block live
6X -8 heads that are 98cc's
T II intake
Converted Holley 650 DP for blow through
To help the block live and help for plumbing the exhust, I am going to install AllPontiacs mid and front motor plate. That way I think I can run stock manifolds and run the pipe in a "U" from the manifold under the motor where the stock mounts were.
My goals are to make under 600#'s of torque so I dont grenade the 5sp TKO 600. Run a small cam that I can cruse anywhere (not sure if a roller or not), and because I will be at 8-1 compression, I should be able to run pump gas on 6-10 #'s of boost.
How much power could I make with unported 6x heads on a 400 with only 6-8#'s of boost?
Does this sound like a good plan so far?
What size/type turbo should I be looking for?
Any tips on this build?
