Found out all the specs about the Engine:
The Vin said is was built for a 1987 Pontiac Trans Am GTA. This is also the same type on engine used in the '87 C4 Vettes.
According to what I've found CR is 9.5:1 and HP output for the 87 TPI's was 235HP and 340Ft/lbs of torque
it's got Gen I heads which are centerbolt but are apparently not Vortec heads which has me confused cause I thought all center bolt heads where Vortec type heads, so I have no idea what the difference is....
Anyway, they have 64cc Chambers, 1.94" Intake Valves, 1.50" Exhaust Valves
I havent actually checked the numbers on the cam but it should be the LT4 350 "Hot Cam" type that GM makes its 218/228 .525/.525 and 112 Lobe CL, but I'll have to get the numbers off it if I can without taking it out, and see what it is....
Anyway, I've got a question here it is:
The engine didn't come with the TPI baseplate, runners and plenum, these items are not cheap even used, I've checked one junkyard near the house and found nothing, got a few others to check, but I'm wondering if a LS1 intake will fit? or would I have to get Vortec heads for that?
