I am finally assembling the AMC 401 to replace the 304 in my 1978 CJ5, and I have two questions related to holes.

One additional thought. I read elsewhere that AMC 401 OEM crankshaft snout diameter can range from 1.3618" to 1.3628" (with most being 1.3628"), and the OEM balancer bore can range from 1.3603" to...

Thanks for the reply. I know this jeep has the Iron duke, but it does have the T176. I have a T176/T18 bell housing (with the special d-stud for the t18 if I ever want to rebuild and install the...
I have an AMC 401 that I am building for my CJ project. I have my eye on a 1982 CJ7 with factory drivetrain (Iron Duke I4, T-176, Dana300) for swapping the AMC 401 into.
Does anyone know the...
