How do you like your vacuum pump?
Think it's worth the 20hp that GZ approximates?

Vacume pump,whats that???
I was told the 235's were too much for a 402ci. Anything done to the heads? How is the low rpm,street driving? I was thinking of loosing my l92's for some tfs heads.

I was wondering what a bigger TFS runner would've done for my motor. Now I know. Its awesome to see your 402 and the extra compression was able to make good port velocity for a serious amount of rwtq down low !!! My motor is only 11.39 to 1, and thank you so much for showing me what a good bump in compression would do !!!!
Congratulations on a very very strong setup !! How is drivability? Sorry if it was already asked and answered, I'm tired and lazy right now. LOL. Nice job guys.

Is this your personal car Nick?
If I keep my car I would be interested to see how much that C6 Z06 rear end conversion would cost. I will finally actually meet you guys at the dyno day and introduce myself, I know we have crossed paths a few times at mooresville.

135-140 traps with some 3.90's and a tire. That beast is going easy 10's, just need to get out of the hole with it. Thats what I am hoping mine will do when I have a chance to go to the track. Best of luck with whatever you do with the car, VERY IMPRESSIVE !! That has definately got to be the highest hp 402 out !!! WOW !!
To the OP. Great job to all the guys @ williams performance. I love to see others going after the na setups. Anyone can do it with a power adder.
