Installing a completely stock '04 truck engine and 4l60 into a '79 Bu, pan, intake, alt, etc....... I put the stock(short) clamshells on some generic block plates with energy urethane mounts. Slid the engine back where I wanted it about 1/2" between the a/c compressor and crossmember and drilled new holes for mounts. Keep in mind this is a cut and hack cheap and quick as possible swap. Problem which I don't see can be avoided is: stock hood won't clear intake and alt. I see to budget solutions (1) notch cross member to lower engine another 1-1.25" (which will probably lead to a pan swap) (2) install a cowl hood and possibly camaro alt (not as stealthy), (3) car intake and move alt. Anyone want to tell me everything will fit as is, if I tune the engine position a little and change the alt or recommend choice 1, 2 or 3?
