Upgrades?

[TonyL]

I recently decided to fix a couple coolant leaks which turned into pulling the radiator out to replace a core support that has decinigrated. Since the front of the truck is off i thought about ding some upgrades since it is easy to work on. I thought about the lift pump, and the water pump, i plan on having the radiator boiled out before reinstalling it. Any body else have any ideas its a 1983 GMC K2500 mileage unknown(reads 90,000 and i'm sure its been around at least once).

Thanks,
Tony

If you're gonna do the water pump, you might think about the injector pump dual idler gear drive too.

How about a turbo...or two? :D

I would inspect the harmonic balancer. Check to see of the rubber is in good shape, and if any of it missing or rotted then it's time for a new one.
