Which Stewart Pump?
What part number Stewart pump are you guys running on your cars? I want to go with a Stage 2, but am not sure if I should buy a short pump, and shim the pulley?
Any input?
Thanks,
Jeremy

not running a stewart, but a flowkooler on my 85. I compared both, and IMO, the physical quality of the flowkooler was much better than the stewart. from an operational standpoint, most likely both are the same. the flowkooler just looked like a nicer piece of hardware. about three years and 10K miles on the flowkooler - no issues.
(summit does not list a stage 2 pump for the 85 corvette - you may need to modify the cooling system for a stage 2 use)
this may work -
Stewart Stage 2 Water Pumps 23113

Stewart Stage 1 Water Pumps, P/N 13403

FlowKooler Hi-Flow Mechanical , P/N 1688

summit will have free shipping on both, but shop for the best price.
