I now have two stock 502's with Bravo drives. They are carbed engines.
My question is what hp configurations were offered in the 502 big blocks by Mercruiser?

Oh yeah and now I have to sell the 18 to pay for these. I would like to get 13k for it. Let me know if anyone is interested.

385 and 415 I believe. Not sure how to tell which is which. The only trouble fellas here ever had with them was the Valve seats. They changed them out to Stellite versions and that was the end of it...(This is my limited knowledge of it all) :D

415 hp for stock 502 is correct.

The 502 came in two H/P combos.
502/415 Stock
502/470 HP/500 Carb and EFI are the same hp.
The 454 family was the 310/330/365/385hps

I'm pretty sure the carb 502's were 390 hp. The efi's are 415.
