Help: 1965 Pontiac 421 wp and crank pulley setup
Hello everyone. I purchased a numbers matching 1964 GTO post car. I took out the original 389, and purchased a 1965 421 from a gentleman who had just had it rebuilt. He had the engine in a 1965 lemans without power steering (he had single groove pulleys). My car is a power steering car. I thought that I would be able to just use the pulleys from my 389, but ran into a snafu. Rather than using a factory style harmonic balancer (that has the balancer inside the pulley), the previous owner of the 421 had a Powerbond/Dayco balancer installed (four bolt). I think this balancer is the style used by later Pontiac 400 and 455 motors. The factory crank pulley won't fit, so any pulley that I bolt onto it won't line up with my water pump pulley. I would like to retain the look of factory pulleys. I called Butler, and he said the easiest option would be to install a factory style balancer ($168). So, I have two questions,
1. Does anyone here have any experience matching factory style pulleys to the newer style Powerbond balancer? If so, any idea what part number waterpump and crank pulleys I would need for a car with power steering?
2. Is there any benefit in keeping the new style balancer (other than cost), or does the old style suggested by Butler as a quick fix perform the same.
Thank you in advance for any advice you can provide.
