Didn't Oldsmobile, or someone modify and Oldsmobile, back in the early 70's create an over head cam arrangement?

Seems it can be the future of the BBC if someone would develop the OHC for the boat market.

Can see it now, a VTEC 588" engine.

I'd be amazed if it handles 6500rpm for long. can you say 6" stroke. must have some serious rods and pins along with a pretty good rod ratio. Does ithe web site specify anything about piston wieght? just curious I can't view the site from my pc.

From 7,755 cubic inches (bore of 6.375", stroke of 6.75") and 7,050 lbs it gave 5,000 horsepower under test in 1944; 7,000 horsepower was the development target. Nine liquid cooled inline four cylinder engines about a common crankshaft. Two contra-rotating prop shafts. The camshafts each consisted of two sets of lobes. One set of lobes for takeoff, the other for economy cruise. The camshafts were shifted axially to switch lobe sets. 580 gallons of fuel per hour at takeoff power, BSFC of 0.43 at cruise. Paul McBride of Lycoming says it was for the B-36 but political pressures caused the B-36 to be fitted with the Pratt & Whitney R-4360 instead. Awesome. A survivor still exists at the Smithsonian's Garber facility. See it if you can. Circa ..

Remeber, the Shott bros had that boat to 145 in the kilo about 6 yrs ago. Kinda wants to chine walk at those speeds.

Remove some (18") of the inside strakes to settle the thing back down if Doc is going to be pushing it.

I hope that the motor goes well for them. I believe that it is going to be a hard sell because of all the uncertainty of the territory. It is a sick design though.

Schubeck's been making bulletproof sht for many years, so I'm sure he's done his homework.

As for weight, not gona weigh more than a blown intercooled tall deck.

The block will be wider, but should fit in most cats and staggered aps.
