Default 502ci 525HP with Carb and Ign

502ci 525HP
Started life as a 502/502 but has been run marine since new. I acquired and rebuilt early this year. Rebuilt by Keith Scroggins in OKC (known marine builder)
New bearings, rings, oil pump, timing set.
Heads were rebuilt with all new valves (stainless/inconel), valve springs and comp 1.7 RA's.
Cam is very close to a 525EFI cam in an Isky grind on 114lsa.
GM Perf Heads and Intake
I have a Victor Jr. Single plane I will include in sale
Carb is QF Marine 850
Ignition is Thunderbolt with HP module

I have run it for no more than 15 hours this season while I worked on the setup on my build. It pushed my 27 Excalibur to 80mph, so it is making some decent power. I can send a video of the last trip out in the boat.

I'd prefer to sell with Carb and Ignition as I plan to reuse everything else.

Stainless Marine Manifolds and Straight Dry Tails could be included for additional money.

$7,500

Last time this engine was run. If you're in need, I'll negotiate various options for the accessories.

New motor is together, I am about to start robbing the accessories from this one.

I am offering it from the air cleaner to the pan to include Thunderbolt ignition. Ill throw in the crossover too!

What is the new motor. Did you build one of the ones you got from me?

I had another 502 block. Built a 540 with it.
