If you want more low end, go for a 292. They have a ton of off idle torque.
Whitedog,
292 is a good suggestion for more torque. But he will miss out on a lot of fun and braggin rights. I have all these mental pictures of a well thought out set up of an old, original-looking engine with a fricking turbo on it! So it boils down to practical vs ridiculousness.
