| all FE pulleys and brackets are interchangeable except crank pulleys (and a few odd notable exceptions but they are rare like the PS belt alignment on a 61-63 tbird without AC). in other words if you have a 64 and you want to swap the balancer to a 68 style, all you need is the 68 balancer and pulley (unless you have a bottom mounted alternator and then you will need a new alternator adjusting arm as well as the new balancer would be so large it would rub!). what this means is if your water pump pulley is not lining up with the crank pulley then there is a problem. i would check to see if the balancer is on the right way first. there are three holes to mount an accesory pulley they should have a machined area around them facing forward. if you are looking at rough cast iron and no surface around the bolt holes then it is on backwards. next, take off the main crank bolt and see how far on the balancer is, the crank should be 1/4 inch or so inside the outer edge of the balancer. if it is flush you have a problem and if it is barely on you have a problem (like a 460 spacer sleeve?). the last thing to look at is the water pump, is the pulley you are using from a V8? 6 cylinder ones will fit but many do have a different offset but even a 289 pulley will work on a 390. what is the number on the pulley? next i would look to see if the water pump was assembled correctly. measure the mounting flange to block length against another and see if it is the same. i have seen them off by as much as 1/4 inch on some cheap rebuilds. hawkrod |
