Default Need some 502's

Hey guys,

I need a new set of 502's and was wondering if anyone knows where I can get some from.

The 502's I have are gen v and i am looking for an engine that will slip in and connect to the fuel pump, fuel injector, wiring etc..

Any help would be much appreciated.

Thx!

Great people to work with. Most all new GEN VI come with a fuel pump boss. There is no fuel pump lobe on the cam to run them.
I purchased 2 brand new and took them apart. I had RMBUILDER Bob Mandra grind cams for me. They all come with fuel pump lobes so I did not have to run electric.

Everything you have on a Gen V will bolt up.

Good luck

Exact same engine as CPPERFORMANCE sells.

Thanks guys! Where i live its just so hard to find someone that can actually work on these motors.

I know this sounds a bit newbie, but if i get a long block 502, what will i need to pull of my old motor and connect to the new one?

Flywheel, pully's belts?
Fuel injector?
Water pump?

I hope the list isnt too long otherwise im going to need to fly one of you out here to help me on it!
