Guess my ET....

Don, your new build is similar to my old 408, 260/264° at .050, 106° in at 102°, .626/.633" with 1.6 rockers, 10.8-1, Curtis Boggs ported Edelbrocks, 727, 9.5" converter that flashed 5400, Victor with a Bigs 950HP, Hedman Husler 1 7/8" 3 1/2" headers, 4.10 S-60, 28" drag radials, Cal-Tracs and mono's.

It ran 6.57 @ 104 with 1.38-1.40 60' at 3260# on pump 93. I shifted at 6400 as it slowed down with anything over 6600 or less than 6400, it was running out of cylinder head. Dave Hughes said it would've been faster with a smaller cam, take that with a dump truck load of salt.

IMHO, you are going to run out of head sooner than I did. As you know I'm don't have much experience with 1/4 mile racing, but feel with your gear and heads it'll lay down on the big end. Your car works well so my guess is 6.70'-.80's, possibly .60's on very good conditions.

This and $1.75 will buy you a cup of coffee in some places. :thumbsup:
