I am looking for a tapered plate that goes under the carb for a 302 ford any suggestions on what it is called and were to find one? Also can you block off the vacum advance on the distubutor and still use it or do you have to get a marine distributor. I am the guy who is converting a 302 from a ford truck to use in my 1978 Shamrock boat. Got the marine carb and starter and just trying to finish things up so I can put it in the boat. Any suggestions out there?
