LOL!.........at 420rwhp.....A well built C-4 will last a LONG time, be quicker and a HELL of a lot lighter. I included LOTS of street driving when I made my first post.
A turbo 400 is WAAAAAAY overkill for a 331.
Sure it will if he never launches it on the brake.
Why don't you put an 8.8 back in your car Bill?
It is lighter and takes less power to turn!
