You could move the cam back to 0 to pull some of the
torque out down low and give you a better run on the
top end.... or you could just put in a programmable
7 MSD box to add timing in after the launch

b 4 i made the changes the cam was retared and it ran 7.6 at 95 mph car has ran 6.7 @103 with 150 nos j heads 10.1 comp , ryan j is helping me with the combo works a lot better than it did.

Slicks at 25PSI ???

Dont know what tire you have on the rear, but 25 psi is high for a slick.If you have a slick on lower it and if that dont work put the Cal Tracs in the lower hole and preload them.Good luck

Like the others have said... lower your tire pressure
and also stiffen up the shock(extension). Take a
video of your launch... you'll learn alot from the video

Yep, tire pressure! Compression is low for that intake port, and cam will not really "use" that head the best it can!!
You have alot left on the table for sure.

tyres are 255/60/15 drag radial , which holes loads the tyres ? more i have 2 hole at diff an 2 holes at frount plate and i ran them in lower hole at diff an top hole frount.

Put the front end one down and try that, every car and track like different combinations, keep testing to get hte best results and the most knowledge (expereince) from the testing

i will give that a try thanks. any other tips?
