Thanks for the write up. This is something I'm thinking about.

I actually spent some time this past weekend hunting around for info on suitable manual transmissions for a '32 roadster with a SBC, and where I might find sources and prices for planning purposes. I have a gut feeling I'd be happier with a manual vs the TH350 in mine now but since I just got it I'll drive it for a while to see if it turns out that way.

So your TKO500 is a 5 speed and I was wondering if there is any advantage to a 6 speed tranny. I guess with 6 the ratios are closer but I'm not sure that's really needed in a sub 2400 lb. hot rod that's not going roadracing. And then of course there's the clutch...it should hold all the power/torque plus some safety margin but I wouldn't want an overly stiff pedal effort. To get a reasonable pedal effort, does it have to be a multi-plate clutch? I run a triple disc clutch in my other car (6 sp) and it holds tons of power, but I'm not yet familiar with the trans/clutch combos suitable for my roadster.
