you arent gonna squeeze a 350/TH350/NP203(or 205/208) combo into a CJ2a... You would have a rear driveshaft that is 3 inches long... if you want to run a 350 (which I think is wayyyy too much engine for a 2a) you will have to run a manual tranny, probably an SM420 or SM465 mated to Dana18/20/300. You COULD fit that combo under a 2a if you planto stretch the wheelbase about 10-20inches...
