Affordable/Best Options New Engine

[nfinholt]

Hello,

Have a beauty of a 1985 C-10. She sat in a garage for over a decade so she looks great but I believe the engine/powertrain has suffered.

I think my torque converter or flex plate has a problem, and the stock 305 has some serious blow-by. I figured replacing the engine would happen someday and I think that's now sooner than later after discovering moister in the oil (milky frothy stuff on oil check stick).

It seems like going to a 350 is the most popular choice. Not currently looking to make a hotrod - rather I prefer her stock. I've seen Crate 350's in the past for a pretty good deal with free shipping. I see a few on Craiglist but none looked that great.

Any advice in the process? How can I keep her rolling and not break the bank?
