Hello and welcome... Nice on the score of the engine.... However there is no affordable off the shelf trans for these types of motors.

Tell me about this engine. Vertical or Horizontal?
If vertical, you need something like a right angle gear box. Or somebody has recently used some belt twisting witchcraft to switch from vertical to horizontal.
1" shaft? If so 40 series Torque Converter possibly.... Or maybe kutzy has some info I do not.

Vertical could use a centrifugal clutch to a right angle gearbox. Or I agree, get a couple pulleys and run the belt to the proper orientation. Another option is locate a Peerless 700 or 820 manual transmission (common among the mower race community) and run that. You have options, may want to look at some race mower builds online and look at what they've done to make them work.

I kinda forgot about those. I read a whole bunch about race prepping the Peerless transmissions.

The thing I just learned about those Peerless transmissions is they only run them in whatever gear is closest to 1:1 ratio and just leave it there.

You can't really shift them on the fly without damaging them, so that's why they just pick a gear and run with it.

You just got the engine? You shoulda nabbed everything that moves--wheels, transaxle (the tranny), steering wheel...
This is a vertical shaft engine, I presume?
