Re: short water pump and a 305

According to the numbers it's a 78 305. The balancer is much fatter than the 350 that came out. The backplate of the waterpump touches the timing cover, TRUCKDUDE239 perhaps someone had already swapped timing covers and balancers for you. When I went to try the short pump I also had the pulley on it and the groves were in line with the balancer so I knew that was wrong. The good news is that I did find the crank pulley I thought I tossed, so I think I'll just change the p/s pump.
LONGHORNMAN, I was wondering if that would be a problem. On my big block I couldn't run a clutch fan because I ran a long pump.
Thanks for the help guys, I'm a recovering big block guy just trying to stay away from the gas pumps. I really thought all small block stuff interchanged easily.
