Small block differences per application

Please don't hold us hostage like that. We'll do anything to help. The difference between a truck and a car engine is slight. Probably just the cam. The heads may be different but probably not. If I had to do it all over again I'd avoid the 727 for any number of reasons. They're heavier, it takes a little more to turn them and finding a junk yard drive shaft for an 904 will be a lot easier.
This and a basic (See post 12,for explained ,a 318/"5.2 Magnum would be a sweet swap here) look at late model Magnums,make sense.FWIW: LKQ ,has a main office in Sacramento. I have bought, and sold...their parts. I actually like a 5.2 Magnum,with a 904 here.Unless you are doing heavy hot rod work. Just an opine.
