I'll let you know after the 22nd., i just put together a 476" rat, that's going in a 66 Biscyne, same car same weight, same everything except 4.56 gears to run both 1/8 and 1/4mi. i'm guessing 10.40 on the Biscyne @ 650HP. I haven't built a Rat in yrs. because i'm totally s/blk, but we'll see. i'll post ET slips from it. It was/is a left over all used parts motor and i really don't know how much HP it will produce, but we'll find out.
And i sure hope it's in the heat, it's 30 degrees here now.
