4-spd vs 5-spd
I recently picked up a Muncie M20 to convert my '68 to manual and I think I have everything to make it happen, but I'm starting to second guess my decision and wonder if I should put a 5-spd in it instead. I currently have a 700r4, which we all know is a 30% OD and 1:1 3rd gear. Fourth gear in the Muncie is 1:1. I'm running 275/60/15 and 3.73s, I think it would be fun, but I'm not sure now if I want to have it run ~2500 rpm just to cruise on the two lane and probably ~3k if I ever hit the interstate.
Thoughts/recommendations on 5-spd units? It will likely never see a track, just a street cruiser. I don't need a bulletproof race unit, just something that will handle ~450 HP/TQ. Ultimately I'd like to do the Power Tour someday, so some fuel economy might be nice. I'm not apposed to a 'junkyard' swap either.
If anyone is interested in a clean M20, it could be bought. Recently rebuilt, I can send you the contact info for the guy who did it. I've got everything - new clutch kit, new flywheel, complete from bellhousing to tailshaft, Hurst shifter, etc. It's an early one, '63 I believe, 10 spline input shaft - I know, I know, not the most desirable of them all, but given it's been refreshed it could be nice for a guy like me that wanted a 4-spd specifically to street cruise and/or a guy looking for a '63 to do a numbers restoration. I'm thinking I only want to do this project once haha.
As always, I appreciate all the feedback, you guys are awesome!
