Hello I need to know were I can get a good CHEAP 5.7 block to replace my 5.0 Tuned Port Injection block, in my 1991 Z. I think that I can use the Tuned port intake, starter,distributor,accesories, except for the injectors on the 350. Do I have to replace the pcm completely, and get a 5.7pcm. Or can I just replace the chip. Basically i just want a 350 tuned port injection engine under my hood. I will greatly appreciate any advice. Thanks :confused:

A '86- '95 carb engine will let you bolt the intake right on. Throttle body engines use different heads, but will bolt the intake on the same. If you get an older engine you need to slot the center four holes on the intake, because gm changed the angle of the bolts on the newer heads. I think you need 350 injectors too. Maybe some one else can confirm that.
