If they are tied to the same prop that is a real slick setup and one does go the wrong way. You leave 'em tired together and run twin 427s in your hot rod. How cool is that.
Depends on how well they were kept. I have been into a salted motor or two that were just fine, other not so much.
IIRC, the marine 427s were center oilers and used cast iron cranks and lower performance (standard passenger car) heads. As stated above, one of the pair will be a reverse rotation so the cam is different and the grooves on the crank that direct oil away from the rear main seal will be backwards. They should have adjustable rockers which is good. If they include the pumps and exhaust manifolds and all of the other special marine parts, those can be sold to recoup a portion of the investment.
Fresh water ones are very prone to freezing and cracking if not properly drained. Even well kept ones have very rusty water passages too. Trust me, I've been down that road with buying Chris Craft 427's. Repairing freeze cracked blocks (and in this case water exhaust too) is not worth it. And, those 427's have cast cranks, center oiler blocks, small port and valve heads, and iron intakes. Really NOT worth the cost. Steve
Two 427 Fords for $5500? Try to find any 427 Ford block for $2750.... If the guy will warranty that the blocks aren't cracked or bored too far, that's not a bad deal. While the sideoiler is the holy grail, unless you're going NASCAR racing plenty of center oilers have made some serious HP (think 390 and 428)...
If you look at the pics, there isnt a lot of pride in the setup, which "usually" means not well maintained.
The guys with money are still running reverse rotation sportsman class sprints here in Missouri. Actually hadn't seen the pics, I hadn't noticed the link.
To keep the props rotating on the opposite direction, it has to do with the wake I think. There is no doubt a boat mechanic on here that can give you a better explanation.
Unless you want to keep correcting the steering they use reverse rotation on one engine. Both props spinning in the same direction will cause wake steer. (beaner, you were sooooo close)
This seller has some old marine 427s as well as SOHC. Marines still had the cross bolted bottom end. Seller also has a NOS 427 warranty block along with a shit load of old gasser wheels, cars, diffs etc.
Hmmm so when you see a boat with 2 outboards on it they spin in opposite directions? What about when they have 3? That's interesting. I never knew that. Makes sense.
The one in the middle spins opposite of the outer two. Yes, on some heat exchangers, and some don't, the salt water does wonders on the cooling passages. I have seen intake manifolds rotted away from the saltwater.
