santa came early....
Great find Summitar!! That 750 may not be big enough, I had to run a 850DP on my 340 back in the early 70's. It was built similar to this one. Ran it on the street with 4.89 gears and a reverse pattern manual shift 727. The 750 couldn't keep up with fuel requirements on the top end. Kept 'shooting ducks' until I put the 850 on it.
Good luck with your new toy. Enjoy!!!
