I'm looking for a 1968 firebird 350, 350 HO or 400. Let me know what ya have and we can talk.

I'd contact Paul Carter. He works at Koerner Racing Engines, in your area. He is a well known Pontiac engine builder.

He has a Pontiac FB page called GTO Freek's Pontiac palace.

You can probably find a '68 2-barrel 350. Most guys replace 'em with something bigger. But, a 400 will be a better choice. And, if you don't have to have a '68, you can probably find a cheaper 400, from the '70's. But I'd avoid any 400 with a block casting number ending in "557".

Don't know what your budget is. But here's a decent 400 crate motor.
