62 had several different HP RATINGS using the 195. Base engine was the dished piston 1BBL carb, standard camshaft, 110HP. Next was the high compression 1BBL, flat top pistons,everything else is the same, 140 HP. Then the 4BBL 4 cylinder, it got a longer duration camshaft, the flat top pistons, 2 1/4 exhaust (up from 1 3/4), the 4BBL intake is a curved runner intake with no right angles in the casting, that was rated at 166HP. Now, what do you want to do? If you want to keep it looking stock, here are some things you can do. If you do not have the 4BBL intake get one. There are a couple of companies that will do custom grinds on the camshaft. Get the cam ground to the longer duration profile, if possible get it done as a roller instead of a flat tappet. Head work, replace the push in rocker studs with threaded. You will need to block the rocker oiler supply line in the head. The original has small oil weep holes in the rocker studs. With the new lifters, convert to the modern oiling through the lifters and pushrods. Port and polish the heads. If you have the 1 3/4 exhaust system upgrade to the 2 1/2. Recurve the distributor for the 4BBL. With those things you will be at 200 HP or better.
