I’d find an AMC somewhere just to slam dunk that in and whip ***!
There was one fella years back that had a 401 in a Javelin. Man! He took so much money! If you know what your doing with an AMC engine, boy can they make some power!
I say do it! The 401 is much like the 340. BIG bore and short stroke.They have excellent heads, too. If you have the fab skills,knock it out brother. That will be a fun ride. They have GOBS of bottom end torque.
