I am replacing a 1981 chevy 350 engine with a 1989 350. I bought the 89 as a long block. So it has no harmonic balancer, water pump, fuel pump etc. I notice that the balancer for a 89 has a pulley that does not utilize the "v" type belt that the 81 engine uses. It uses the flat type belt with 3-4 grooves. (hope that makes sense). The balancers don't appear to be interchangable. There's a difference in the width of the two. So..... what's the easiest/least expensive way to get all the pulleys (thinking of the v groove power steering pump and alt.) the same? It doesn't look like I can just use the v groove pulley off the 81 on the new 89 balancer. I may be wrong, just asking. I haven't bought the new balancer for the 89 so it's hard to compare.
