Missed on this combo?

yes it was in my black R/T.

X block, 4.125'' Molner crank, Diamond pistons (13.8 comp), custom grind solid roller (662/653 lift 278/288 @50 dur), W2's, Holley Pro Dom tunnel ram with 2- 650's. LA TTI headers.

i only did a few passes. off the trailer it did 10.76 @ 126 mph. 60' was crap with best of 1.55. usually 1.60. car was 3800 lbs. i did no tuning at all. i wish i would have had time to tune, as i think 10.40/10.50's would have been possible. i never touched the timing or played with the carbs.

i sold this engine last year. it runs 133 mph in a better set up chassis and the car is 3400 lbs.
