A833 on a 90's 360 magnum engine

The problem is two fold. The early cars used a small bell and very small clutch, what, 9 1/2? or something?

You don't have much "tunnel" room although I've been told you can beat the "pinch weld" to death

The second issue is engine balance. 5.9s are weighted different than a 360LA and use a different flywheel weighting to achieve balance. There ARE NO "car" flywheels (OEM) for a 5.9 with proper weighting, so you either have to create one or look around aftermarket.

Also, I was going to "go stick" in a 360 Dodge ram. THE CRANK was NOT DRILLED AT ALL for a pilot. I would have had to pull the crank, or else "rough drill" the crank for pilot shaft clearance and then use the 'large bore' pilot which fits the converter bore, which is very viable if not a bit "red neck"

EDIT ^^Both typing same time LOL^^
