Selling pair of marine big block Chevy 454’s, approx 500-520 hp or so based off having cams and past builds I have done. Bought boat for parts I didn’t build them, so I can only explain what I know or have been told, guy said had approx 30 hours or so on them, built with voodoo cams I do not know specs but would good, track warrior intakes, roller rockers, soulds like they have gear drive timing sets, arp bolts, I posted pics of the engines, compression test numbers and also cut oil filters (you can see them for inspection) to make sure they are healthy and all checks out, I also have videos of them running. Like I said, I don’t know the build specs but somebody spent some time in these engines. Look to be in great shape!! I am listing as a pair and will not seperate at this time. These engines will be complete with accessories. The wiring harness was cut at the boat, but I probably have other wiring harness if you need them or use yours, engines will come from the flywheel forward no transmission or bell housing because of boat variations. They will be on a roll around engine cradle for easy loading and strapping.



11,000.00 for pair picked up Olmsted falls Ohio 44138 I will not ship them. You have to come inspect them yourself and pay cash only in person. These are as is with no #Warranty I took the extra steps during compression testing and videos and also cutting oil filter filters to make people comfortable with what they’re getting.

plug wires are on backwards

That’s fine, I didn’t build them or care, run fine you can swap them around when you buy them, thx for the useless reply.

Pretty valuable information to the potential buyer if you ask me.

lol if someone putting wires on backwards who might have had a reason makes or breaks a deal, then don’t buy them. Smh go to work or something, if you’re not buying? Move on I didn’t need selling lessons I only been at it for 20+ years lol

I mean, is it that big a deal? Maybe the user before didn’t wanna see the other style tops with nubs sticking up, it’s not like wires are directional….

My bad, when I read plug wires backwards my head went to incorrect firing order.

That’s the deal breaker, just think how much more HP you’ll get when the plug wires are straightened out.

I was thinking firing order also, when I first read that.
Don't think I would have ever noticed on my own.
Surely not as important as the borescope shots or sectioned filters to an interested buyer (nice pics. not usually included).
Not chiming in to muddy up the sale, but does get ad back to the top of new posts list
