Dyno and pics of a SLIGHTLY modified 502 Mag MPI
Here are some pics of a slightly modified 502 Mag MPI that we just finished. It is now 547 ci with Dart Pro 1 heads, Holley EFI intake, 2000 cfm throttle body, MEFI 4 ecm, etc, etc, etc.
I have received a ton of calls lately asking what can be done with a 502 Mag MPI to make more power. I thought those guys would like to see this. This may give you an idea of what that engine can look like and what kind of power it is capable of making. It ended up making 688 hp and 665 ft lbs of torque. It is going in a 28 Advantage of a fellow OSO member.
I received it as a stock 502 Mag with damaged Pro1 heads and a burned piston. Here is what it looks like now. Enjoy, and thanks for looking.

Nice work Eddie and some good numbers.

Sounds like something I'd like to do. How about reliability and hours before refresh is needed?

In the video the accessories were not turning. That tells me the horsepower number is not real world. Just curious why you dyno with the belt off ???

The engine was making 415 hp before I got my hands on it. It now makes almost 700 hp. Regardless of whether the accessories are turning or not, I think it is a pretty good jump in power. The customer seems to be pleased with it and that's what matters to me. I really wish I could run the accessories, but I can't at the moment. I will get it set up at some point.
