I hope you're planning on revving pretty high with 4.88 gears. I'd say 6.7-6.8's don't know if 6.5's will be easy but can be done I'm sure.

I did a 347, 12.5:1, Z304 Heads, small solid roller in a fox body with a 125 shot and it went 6.40's 109 first pass. The converter is key, 99% of people get it wrong and wonder why the car is a pig but makes a bunch of hp on a dyno, but is lame at the track

Remember, track's conditions vary (altitude, prep, etc.), drivers, tire conditions, etc, etc.

Rarely do I see anyone post track prep conditions. It is wonder why the fastest times in the country are all by the coast, *cough - cough*, sea-level.

The drag strip has a ton of variables. It is tough to compare combination vs. combination.
