Are there any good/reputable suppliers out there for a relatively mild small block crate engine at a reasonable price? Something that runs on pump gas, has good torque, and probably in the 300 to 350hp range.

I've always built my own so I'm not really aware whats out there, but I'm trying to help a non internet savvy friend find some options since he needs a total replacement and isn't technically savvy enough to build his own.

Thanks for any feedback!
