    Your only option is to drill and tap a 7/16"X20 hole about 1 1/2" deep. None of the early 265"/283" cranks had drilled snouts they were all press fit balancers.

    They used to be plentiful & cheap & I've made good 302s from them Never used them in 4.195" bore to make 331 cubes but that'd be a cracker combo for sure

    When you look at it, Nascar is doing esentually just that, they are running 3.2 stroke cranks with 1.880 rod bearings with 6.2 lg rods in the 358"motors and no one can question that they run 9,000 rpms for 500 miles with few failures. The other factor is that is not much torque but a ton of HP, so a light vehicle such as a dragster or 2,000lb roadster would be haul ass. In fact we're looking at trading the 66 3700lb Biscyne for a 1934 chev roadster with a 306" s/blk that runs 8.18 in the 1/4 mile, but my friend don't want the engine he wants to stick with his b/blk and let the guy keep the motor (high maintenence).
