The only other motors that can be used are AMC specific motors: 258 I-6; 304, 360, or 401 V-8s. The auto tranny used was an AMC-cased Turbo Hydromatic 400. Finding a 258 or 360 is usually not a problem. 304-powered J trucks were pretty gutless and 401s are by far the best (and most difficult to find) motors.

just remimber that the 304, 360, and the 401 are all the same block so you could just start with somethin and go from there.

If you can't duct it, f#*% it!!!
