Rebuild 502 or repower with 525
Have a Formula 27PC with a single 502 EFI (replaced a 7.4 carb) and it runs ok but could use a few more ponies. Do I rebuild the 502 and punch it out, build it up or go for the 525 EFI complete? Top speed is 48 MPH using a GPS, but if I fill the tanks and have 6 folks on board getting out of the water is an bit of an issue, top speed will be 40 MPH.
