Cliff Ruggles's 1973 Ventura
(In His own Words)
Daily driven 1973 Ventura, with 1974 GTO hood and Shaker assembly.
TH400 transmission with Continental "tight" 10" converter, 3.42 gears. 275/60/15 MT Drag radials on stock 7" rims.
Best run to date 11.39 @ 120mph, in full street trim, thru quiet mufflers, on 89 octane fuel. 60' times 1.61, 7.20 1/8th mile at 96 mph.
We were not able to dyno the engine, but would estimate that it makes around 560-580hp and around 600-620 torque. It would be happier with a bit more gear and/or converter.
Street manners are excellent, near smooth idle, with just a hint of "attitude", smooth right off idle and excellent throttle response.
