Distributor recurve

[Goin Broke]

I am looking to freshen up my stock 351 dizzy. If anyone has had this done recently please advise who would be a good recurve company to go with.

I did my own. My distributer came with 36* mechanical advance. I welded up the windows in the advance arms and reground them for 16* and 20*. I adjusted my advance rate by bending the tab that holds one end of the big spring. With less preload on the big spring I get total advance by about 2400rpm's with the stock springs. There is a window in the breaker plate that allows you to adjust the spring tabs w/o disassembling the distributer. There is a great write up here http://reincarnation-automotive.com/Duraspark_distributor_recurve_instructions_index.html on DIY. I think the owner of the site does rebuild and recurves as well.

I did it the same way. My Duraspark had too wide advance slots, so I welded them up and filed them back into shape, but with smaller slots. Then I adjusted the advance rate with different springs.

BR Motorsports Ignitioneering can rebuild it better than new and recurve it. You can google them if interested as I don't have their URL handy. 1-800-328-3333.

I know those guys, sort of. It's mostly sprint car stuff. They got in the ignition business because sprint cars used to use magnetos and they need attention.

Thanks for the assist guys. I will give them a call.
