You need your car to "git up and at 'em" at the 40 ft mark. The bleeding stops THERE!!

Then you need a bigger bore and shorter stroke with a big cam and GOOD flowing heads.
The 4" stroke with a mild cam will still be a tire fryer with a lighter good flowing head
Ummmm.... your about to make a bunch of people that spent a lot of money get very angry..... LOL :D
