Re: 3.54 vs 3.25
39,
When you mentioned 1st gear for you is almost worthless made me wonder if you already had the 15/29 first gear in the trans now. Obviously third is still one to one
so high gear on the road won't change. The motors in my '32 and '41 pickups are near
what you are running and first gear for me is very worth while ,both trans have the 16/28 gear set.
The cam in my '32 makes power above 3000 rpm and the drivability went to hell when I changed to 3:78's from 4:11. Something to keep in mind as the rear gets taller.
I do have a Columbia with 3:78's in the '41 and in OD I think the ratio drops to 3:22
or somewhere close. The Max 1 cam has no problem motivating in OD.
