i got one on loan off my buddys s10 (he told me because its off a chebby it'll 10hp....i then proceeded to smack him.) im gunna try it and see if i like it or not. so far everything seems to be the same. but thank you for all the imput. and the alternator braket is a 66 "poly" 318 bracket... the car was originally a poly 318 and i smoked it, shortly after rebuilding at...a poly doesnt like 5000rpms and the "LA" bolted right in. and a used all original front bracket assemblies, to give it a different flare.
