440 vs. stroker 408 build?

408, When you get right down to it, it really is what ever YOU want and what your doing with the car. Things like leaving in the /6 T-bars is OK for a street s/b , buuuuut probably not to cool for a all iron rb. Though it will be great fro weight transfer at the track. And or what your shooting for, it really is a cross between what the wallet has and what you want to do with it.

It's all, "Combo dependent."
(I think this is becoming my favorite saying as of late)

You can for shurly get a decent power plant from a mild 440 build.
Torque Torque Torque Torque Torque Torque Torque LOL.
