Looking for some friendly advise on my engine. Motor was already in truck and I pulled it and broke it down to know exactly what its got and do some freshening up with new bearing and seals ect. I would have left it alone but I would like to build on it and put a larger can. Its going in a 82 swb chevy, th400 trans, 2400-2800 9.5" stall, 12 bolt posi rear haven't checked gearing yet.
This is a weekend street beater, may see track in future.
Motor specs that I have found out so far
350 4bolt .060 over
400. Crank
Speed pro h860cp .060 pistons
GM 340292 292 Turbo heads they look untouched to me.
Can't find good markings on current cam but its going by by, hydrolic tappet
My thoughts currently are going air gap intake, comp xe274 cam, and maybe some runner clean up on the heads. I haven't gotten the springs off yet to check them but they are a double spring.
In my mind I'd like to shoot for 450+ HP and tq with a nasty idle yet keep some vac for breaks. If I can't, I don't mind a pump. Speed pro says 10.5 comp with 64cc heads, but I'm not sure if mine are 58cc, thats what I measured with a siringe and fluid.
