Hi all, I have a '50 Merc with a Chev 350 ci motor. It is hooked up to a '41 Dana rear end with a 4.27 R&P. Nice off the line, but as you can imagine, not so good at 55 mph. I'm not rolling in cash so doing a tranny change is not my first option. I'm wondering what R&P gear ratio would be be suitable for the T350 automatic trans. I don't want to change the whole rear end, just the R&P. I may not be able to match the ideal chevy gear ratio, but there are some Dana R&P swaps I might be able to do at minimal cost. Any help would be appreciated, thanks!
