45%rear and 55 front weight 119 wb 1960 Chevy 33x16 tires. 577 cui 5' bs wedge bbc whipple screw efi controlled. Mostly 1/8 mile. 11' mark williams curently 4.30. Dont have a trans yet so i wonder what to look for, 2 or 3 speed? And what trans and rear gear ratios? Heavy car says 3 speed but the high power level maybe lets it get away with a lighter and simpler glide? Will run a converter. Many things to consider and are trying to figure out what trans and rear combination that will work best. I dont have any experience from this power level and havent ran this car before so a big tuning window is needed and the purpose is to learn and have fun not to set a new world record, on a good track i think realistic et performance shuld be 4.2-4.5. Thanks for any help!
