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.
