I am wondering what issues I wil be facing by swapping a 1998 Vortec 350into my '66 Chev 3/4 ton. Will the'66 harmonic balancer v-pelt pulley bolt to the '98? What about the non-reverse water pump? I have heard that the flywheel will not bolt to the newer engine. Is this true? What about the pressure plate if I do need to get a newer style flywheel? The engine in the truck now is a smallblock 400 but is still running the 3 bolt starter with the older style 4 speed behind it. I have an aftermarket 4 barrel intake to put on the engine that is made for a Vortec and it has the HEI upgrade already. Thank you in advance!
