Hey guys I'm finally getting around to starting to this project I received 8 years ago. I was given a 87 GTA without motor or trans and have been collecting various pieces over the years and finally have the time to do this thing. The car is a Flame Red Metallic exterior with the Carmine interior and is an original 5 speed car. I am in the process of getting my World Class T5 rebuilt as we speak and need help with the engine details. I have a 350 1 pc rear main seal block in the machine shop and will be using stock crank and rods and some Probe forged pistons for the short block. I picked up some 113 Corvette heads yesterday for $250. I need to upgrade the springs for the larger cam and need to know if any machining is required and also need help with selection of a good roller cam. I am thinking about the Comp Cams XFI 260. I also picked up the matching lower intake from the 91 Corvette. I want to use the stock TPI intake set up with porting and I am not sure what the compatibility is. Will the 91 Corvette lower intake accept the fuel rails, runners and plenum from an 89 Camaro TPI? The 87 GTA is a mass air system and I'm not sure if the pieces will exactly work. I believe the Corvette lower intake will work with the Camaro runners and plenum and hope all the stock wiring, sensors match up. Any input would be very helpful.

 

anyone?

 

Good luck with your build. I'm building up an 87 GTA too.
