I'm gathering parts for almost the same swap. I needed a pump to put out @50 psi for the '97 454 that I'm swapping in. I went to Napa and got stock '97pump for a 454 and replaced the one from the '89 Blazer tank which put out@ 35 like you said. They looked and fit identical. K10Hunter- you could probably just remove the pump from the '89 tank, extend the pickup to where the bottom of the pump was and just use the stock mechanical pump on your engine. I'm not sure about the gauge compatibility though. The new sending unit is something like a 90 ohm and the gauge in my '63 is a 30 ohm, so I had to re-wind the sending unit to work with the original gauge. Not sure when they went to the higher ohm gauges.
