A while back Powerboat Magazine posted the parts and part numbers required to convert a 502 MPI to a 500 EFI. I think it was a Teague On Tech article. Does anyone know what year/month the article was in the magazine or know the parts and part numbers required for the conversion?

I burned a piston in my 502 EFI, went .030 over JE 9.6:1, 315 CNC AFRs, complete 500EFI setup ( had 20 hours on it), Bob Madara hydraulic roller cam, EMI exhaust. Dynoed 572 HP @ 5400, 606 tq @ 4500 fully dressed. Ran flawless 2 years. Sold the boat this spring.

Found it! Thank you!! You just saved me a few nights of flipping through PB magazines. I would love to hear how it goes and if you have any tips.
