318 temp use

Just thinking about this, it might be ok. I have the trans and bellhousing mocked up w the engine no clutch or flywheel, and the trans spins freely when in gear. I can only assume byvthia that the input shaft is not hitting anywhere inside the crank.
That's the way; uh huh,uh huh.As long as it stays that way when heated up!

Don't forget to adjust the pilot hole in the bell, to put the trans centerline on the same centerline as the crank. Do this after the block and crank are finish-machined and are ready to mate
