Anyone know what that block that actually is? I've heard thats its anything from a very early 3.8 Stage 1 block to gnttype saying its an 80 4.1 to an early carbed turbo block??
Also called a buddy of mine who works for Recon in Philly who said that casting # is for 79-84 3.8 litre NA and Turbo apps.. Said the casting #'s are different for the 4.1's, BUT being that it was early 80's GM, anything is possible..his words exactly...Good luck !
