This motor will be put into a 3500-3800 pound car. it'll be infront of a th400 and spinning a 3.73-4.10 rear geard 12 bolt with posi. I'm looking at either a homebrew 427 big block or a 406-415 small block stroker. it's main purpose will be street cruising and some trips at the track. I like the idea of a short stroke for faster r's but a small block will be an easier fit into the car and with a small block i can use my $300 headers i "had: to have.LOL also looking for longivity, I'm not into building motors each year.
