cam shafts for a HP 500 EFI, need help fast
I broke a cam shaft on my '99 HP500EFI today. What cams should I replace them with. The motor is essentially stock, except it is bored 30 over with flat top SRP pistons.
I want to get it fixed fast so I do not miss much of the summer.

The stock one is probably the best one. It's already pretty wild for a 502. Call Crane for a replacement. I'm pretty sure they make it and they'll charge half as much as Merc.

Re: cam shafts for a HP 500 EFI, need help fast
Just to close this out, after much discussion with many sources about whether the Crane cam is the OEM replacement, I got a Crane model 164621 cam from Teague Marine for around $350, Mercury wanted $860 for a replacement. According to Crane and Teague the 164621 is the OEM replacement cam. It is a billet cam with a press on distributor gear. Although I have not removed it yet, it appears the distributor gear is what broke on mine.
