93 Barchetta Vortec upgrade
So Im replacing the stock 93 4.3 with a newer ATK 4.3 Vortec crate motor. Running into issues now with oil dipstick and tube, Harmonic balancer, Water pump clearance and choke on the new intake. Also it seems the thermo is offset and could restrict the hoses. Anybody done this with carb? I am using an aluminum mercruiser oil pan. Thanks for any help.
