Default Re: COLUMBIA with 3.78 gears

my first columbia was in a 34 w/17'' stock whls w/?cam, was gutless, needed more rpms to run good. next was a 1940 w/ mild eng ?cam, 25t linc gears 4.44 rear,28''tires, sold it man said ran great on hiway at 80mph. next[stii have] rdst pu w/8ba, 400jr cam, heads 3/2s, 26t linc grs, 4.44 grs 7:00/16 trs, was awful to drive w/400jr cam needed to be excelerating and more rpm's than i had the way i drive. pulled the 400 cam and put back in the stock 53 merc cam, a completely different car, great to drive. next, i'm still working on it, i'm out of linc gears so its a 8ba, stock cam, orig edlbrok blok ltr hds, slingshot int, 39 linc gearbox w/48 ford gears, columbia w/4.11 gears,31'' 7:50x16 trs. i like the 4.44 rear gears but you need 25 or 26 tooth trans gears to run them or you run out of rpm's quick. i like to lug around in hi gr at 35-40 hph. cam, trans grs, tire size, how you drive = rear gr ratio.. just my 2 cents
