Truck engine swap

Pin It

I recently added a 1986 Chevy C10 Silverado to the fleet which was the replacement for my 1992 Accord.  I drove the truck around for a few months.. put a couple thousand miles on it and then the transmission went.  I figured I would pull the engine and transmission which is extremely easy.  A couple hours and both were out.  I sent the transmission over to a guy I work with to be rebuilt.  It's a Turbo 350 transmission, one of the cheapest to rebuild so I figured we might as well do it up right.  Going with some racing clutches, B&M stage 2 shift improver, and a 2400rpm 12" stall converter. 

When I started pulling the engine apart I was not happy with what I found.  The valve covers were filled with the tell tail sludge of a internal coolant leak.  I pulled the intake and heads off, but all the gaskets looked fine.  I never did find hard evidents of a gasket leak.  Seeing as how this is only a 305 V8 I figured I would take this opportunity to upgrade the engine as well.

Here are some photos... shiny bits in the transmission pan.. no good... and baby poop in the valve covers!


After much searching I settled on a performance engine from ATK high performance engines.
