Chassis Dyno - Last Run 427 High Riser
Self built 427 SO, stock stroke, 429 ci., Dove aluminum High Riser heads, mildly ported, 10.5 : 1 CR, original holley 780 cfm LeMans carb, vacuum secondary, on an original single four BBL , dual plane, Hi-Riser intake. Chassis Dyno is at Performance Engineering, Hamilton, OH.
Carb jets changed, and timing adjusted by Performance Engineering. Picked up 80 ft-lbs torque and 60 hp by chassis dyno tuning.
With a 20% loss, estimated max flywheel torque is about 600, with about 570 flywheel HP at 5900 rpm's and still climbing.
The torque curve is pretty flat.

460 Ford Tunnel Ram in Jet Boat
Engine as when I bought the boat. 460 , likely standard 460 heads, Weiand tunnel ram. Dual Holley 4 BBls, vacuum secondary. Runs sweet. Headers are water injected which muffles the noise, and keeps the pipes (collectors only) hot to touch, but they won;t burn, unlike the primary pipes which will.

1978 Cobra Jet Jet Boat
Boat manufactured by company called Cobra Jet. 18 ft long, shallow V-Hull. 460 Ford, tunnel ram, berkley jet pump drive.
The boat accelerates like a high performance car, unbelieveable. Great boat for water skiing. The only boat I've ever only needed to give it part throttle to pull up a skiier. Full throttle will rip you arms off. With full throttle, the boat will accelerate so hard, it leaps out of the water before the skier gets even half out of the water, and you have to let go at that point.
The boat is easy to trailer, to launch, to load on trailer, etc. The best boat I have ever owned. Easiest boat to use, most fun with lowest maintenance.
Kind of like a cobra, but on the water.

1970? Howard 17 ft V-Drive
I think it has a HallCraft V-Drive unit if I can remember correctly. Haven't messed with it since about 1995. Maybe it'll be a winter project.
Engine is a 1962 409 Chevy, 380 HP model. 2 Blade prop.
Unlike my jet boat which kind of fish-tails its way around, this thing rides like it is on rails. Completely different feeling than the jet-boat.
