Should run low tens in the quarter pretty easy.

It should be in the 10's, but it is all about engine/trans/rear/suspension/track surface combo

What was your 60' last time?

Thanks Guys,

The numbers I'm going to give is with the old basicly stock 460 from this year

Here are the performance levels without making any adjustments to the chassis or engine because I had a fuel problem.

Launch - Footbrake 2,000 rpm
60' time - 1.53 best (6 passes all in the 1.50's)
shift point - 6,300 rpm (about 150' short of the 1/8, laid down)
1/8 time - 7.22
1/8 mph - 93.68
1/4 time - 12.22
1/4 mph - 73.56

This performance as I said was from a stock 460

063 closed chamber small valve heads (stock)
heavy TRW 12.3:1 with the 101 cc heads
Scotty brown solid cam 636/595 265/275 108

Everything else the same as called out in the orginal post

Will that big dome clear the chamber in a 781 head?

I have run a 48cc dome on my old 049 heads. Not sure if 781s are the same chamber size?
