But I have an A-body, I have a custom 8" ATI converter. A trans brake really woke up my launch. Foot brake only gets me a mid 1.4,
I would go with the 4.25 crank.

Hi Mike: I'm kinda in the same boat at Skip hence my post. I'm probably 3700 lbs with a 1.47 best 60 ft at 129 mph. Best 1/4 mile time was 10:29 with a 1.50 60ft at 132 mph. Mind you our elevation is at 2200 ft. 28 inch tire with 4:10 gear. Current convertor flashes to 5000. It feels like the engine would like more convertor, like 5500 maybe even 6000..
