I would say you hit your goals perfectly..... Any more power might work against you if you are using a Bravo 1! Decent dock manners, 600HP/TQ, I would say this is pretty much the default 502 upgrade!

Yep. I'm happy with the results. I was hoping to keep it "Bravo 1 friendly"!!

I by no means am an expert at reading dyno paperwork. But isn't the low (lean) 0.39-0.42 BSFC in the heart of the torque curve making anyone else a little nervous? Not an expert, but that is where I was told to be concerned.

I think alot of guys today are still going off the carb sizing thought process from 1985. The modern high performance marine engine is a far cry from a 400hp mercury 454 cyclone or a hopped up 330. We are now seeing N/A engines making 600, 700, 800hp. A 465hp HP500 ran just fine with a 800 holley. That's 465hp at 5200rpm. A far cry from 600hp at 6000rpm.

Or there are guys running N/A 540's hoping to make 700hp but want to keep a stock 800 holley on it. I think it goes back to the days when everyone threw a dominator on a 400hp engine and wondered why is was a turd.

I wonder if the the factory EFI from a '96 502 mag would support that HP?

I don't believe so. Maybe after some extrude honing and what not you might get close .

No. Even the 500EFI has a hard time with this HP.

MPI has a good intake for a tow truck.
