I'm in the same boat, I've got spare 300ex parts and thought about doing the same thing. It appears that it would work just fine, the only thing I didn't look at was where the intake and exhaust connect on the 300ex but I believe its the same.
I'd be curious to see if it worked with positive results!
i dont think a 300ex have 4 valves does it? i have heard of people doing this mod though
it sure does....2 intake...2exhaustQuote:

well i found out for sure. the trx engine rotates the oppisite of the 300ex so you would need a 300ex piston and head but you will need to get a 300ex cam built to run in reverse im told web camshaft will do it.hope this helps
