Well, my best track time wasnt as good as it could have been. My clutch was slipping a little back then, and ive since went from 100 shot to 125 shot. Soooo, track times should be better next time I go
And you'd be suprised, there isnt much of a weight difference between a v6 and v8. Just remember, the whole thing weighs no more than 500 lbs or so, and if my math serves me correctly, you're only removing 17.5% of the block, so what is 500 - 17.5%? Not much.
And the main problem I have, is I have alot less motor, to push the same weight you have.
