After Eddie put the engine in, finishing up the rigging, and did some test running I picked up the boat and my first use was a 300+ mile round trip and had no issues with the engine.
Started out at Kuttawa, KY (Lake Barkley) and ran up the Cumberland River to the Nashville riverfront docks. Stayed a few nights along with a run to Old Hickory Lake then made the trip back to Kuttawa.
I had 6 people, luggage, two coolers, and many cases of beer.
I made this same trip 4 years ago and this time I was able to run at a higher RPM which allowed for a faster run and used about the same amount of fuel as the old 509 motor.
Extremely happy with Eddie's service.
Eddie can you put together a kit w everything but the shortblock? Heads, cam, intake, TB, ecm tune, and ecm bracket? It can be the YP680
What would you recommend if I wanted to get another 125hp or so out of a stock 502mpi? The motor shouldn't be having a rebuild for quite some time yet so I don't want to tear into the bottom end.
Just trying to get an idea of what's involved to get to the 540-560hp level without affecting longevity drastically?
Sure, but it will be a ballpark tune. They all differ a little bit and the best way to do it is to put it on the dyno. Give me a call when you get a chance and we can discuss it further.
Shane, glad you guys had fun. The pics were great. I would love to make that run one day. Glad the boat ran great for you. Thank you again for your business. Talk to you soon.
If you chose to change the stock cast iron heads to aluminum (plus the above items), then 600+ hp would be possible from your 502ci.
That all sounds terrific. Height under the hatch is at a premium (I think there might be 3"-4" of clearance with the stock 502 manifold so while I'd love to change it out, we may need to go with a front feeding version.
Just starting to think about the project now - no definitive timeline.
The Holley setup is not much taller than the stock 502 Mag intake. I will check on the exact height of it and get back to you.
