first off i have an '88 Trans Am 5.7L TBI, 5 speed trans.
here is a direct copy/paste of the stuff i got with the car which the P.O. had listed in the ad.

Included with the car will be a 383 crank, weiand Team G intake, cam (specs are Federal Mogul CS-186R Cam.. 230* dur, .480" lift, 109 lsa. have lifters and pushrods aswell), pistons and rods (will make 9.5 compression with 64 cc heads), oil pump and also a set of heads which i can get a casting number if need be. With the engine parts you should be able to get atleast 300-350hp if not more.

Any thoughts?
also is there a vacuum line diagram somewhere? i have like 6-8 disconnected vacuum lines. a few electricals disonnected and some wires that are just plane snipped and go nowhere.
heres my thread on the engine problems...
