Would 400 HP be do-able without having to worry about shooting rods and everything else out the side of the block? Just trying to make a powerful motor for the street, and have some fun!
That's alot more realistic. I know many will disagree with me, but 500 or more horsepower on a street, fun type car is not needed. Cool, but not required for some push you back in the seat fun.
Just to add, HP #'s are fun to talk about and brag if the're huge:D, but that's only part of the combination. If your willing to run some gear and a good torque converter, you could easily have a 12 sec. car without having to go radical on the engine set-up. And that can be alot a fun.
