Thermo-QUAD!
Yea, what moper said. The T-Q @ under $25 is a steal and worth the rebuilding kit and other things you don't have IF it needed a rebuild. There simple and basicly an easy carbto work on. The AFB/AVS are really simple.

Your gonna like a 360 with the 340 cam. The only thing I see is the T-Q on the RPM's squarebore needs an adapter that will seriouly decrease hood clearance.
Take the whole engine and sell it.
