Re: Jeep amc bolt to IH amc
It depends. As I understand it the bellhousings for Scout II applications are all the same for all IH motors including the 152 and 196 slant 4 motors, as well as the 304 and 345 V8's, and the 392 V8 for that matter which wasn't an option in a Scout II but will fit.
However, for Scout 800 applications the 4 cylinder bellhousing tilts the motor something like 15 degrees. Plus I think the length of that bellhousing is different from a V8 bellhousing. So as I understand it for these reasons you can't use a Scout 80/800 bellhousing in a Scout II.
A couple of other things to consider depending on which IH engine you want to install are:
1) There are differently weighted flywheels on the 4's compared to the V8's which will bolt up but are not compatible and will cause driveline vibration.
2) If a Scout II came with the AMC 258 from the factory, the motor mounts are different from the motor mounts for the IH motors. In such a case you would need different mounts.
