Diff ratio help

Something in the lines of the last 2 posters. 3:08 is too tall with the transmission you have. 6th gear would be useless until 100mp

i know that there's a few flavors of these boxes in regards to 1st gears and which OD gear, so i'd say pick one that will be most usable in OD and compliments the gear spread the best.

with the power you have the starter gear is a really a non-issue, and i'd guess you'd have trouble not totally just blowing the tires off in first or second.

running some quick starter and final drive numbers, i'd probably pick something in the 3.7~3.9 range

souns like a cool projects, let's see some pics!

It's still a old original, untouched car at present. I'm just collecting all the pieces I want for when I find time to put it together. Got a 448 Hemi coming from Better Built Performance, 650hp, 610ft/lb - great guys to deal with! - the tremec six speed from American, and now sorting diff and rear suspension, wheels, tyres, etc. Car came with 14 inch wheels, 70 series tyres x six inch wide. I'll be going 17 inch wheels, with 45 series or 18 inch 40 series and hoping to get 12-14 inch wide at rear 8.5 inch wide tyres at front.
