Ryan; We need to know what engine your building and other things about your car like trany and rear end your planning on running. Hopefully it's a big block to get that thing rolling out of the hole. If your planning on running a big stall converter you don't need low end torque. You'll need mid and top end, but it's all about the money.
If it's a small block then you will probably need more low end because in a heavy car like that it will probably die out of the hole with all that cold steel, even with a big stall.
There is nothing like cubic inches to get heavy metal rolling. Let us know what motor.
