I've got a 429 from 66 Cadillac that I want to build for a project and have some questions. I've had other 429 Cad's but they were good enough that I really didn't want to rebuild them. This one burns oil like crazy and I'm going to tear it down. It was a common motor as it was used in pretty much every Cadillac from 64-67 but there doesn't seem to be much around for increasing power. It has potential as it was rated at 340 hp and I think a torque rating around 390 from the factory with around 10:1 compression. Having owned a few 429's that were factory stock and in better condition than this one I know they can be quite potent. Cant seem to locate any aftermarket cams, intakes, etc for this motor. Heres what I had in mind: Punching the block to .30 or .60 over, getting new pistons, rods etc. Moving to electronic ignition Custom cam Having the heads ported and polished Also heard of modifying a stock 429 intake to fit a larger Edlebrock carb but I've had pretty good luck with the Quadrajets in the past if they are properly tuned. Anyone else have any suggestions for this motor. Thanks in advance.
