4-30-20 day for the 430 CanAm aluminum big block Chevy

[JoeC]

from what I read Bill Jenkins ran a few different engines in 1970 and 1971
the articles are not always accurate so its hard to say what the engine and HP was but I have read that the 1970 and 1971 Pro Stock cars (Ford Chevy Chrysler) were over 700hp

In Super Stock and MP Bill ran the ZL1 and L88 and L72

In Pro Stock he ran the CanAm 430 engine
in match racing he ran the CanAm 494

here is a screen shot from Drag List 1971 PS Mountain (match race) Can Am 494
where Bill ran 9.265 at 141 mph

says the 1971 record was 9.265 at 149.76 mph


John Greenwood ran the ZL1 in his Corvettes for SCCA and FIA road racing
here is a quote about the #49 Corvette where they claim the Traco ZL1 was 750HP


"When it was originally converted, the #49 BFG Corvette received all the popular Greenwood innovations: adjustable suspension, above, notched rear arms, rapid replacement radiator, and quick camber adjustments. A blueprinted Chevrolet ZL1 all-aluminum 427-cubic-inch engine, producing over 750 horsepower at 6,500 rpm, was chosen to replace the factory L88. During the restoration process, the #49 car was fitted with a potent Traco 427 ZL1

Driven by John Greenwood, above, right, 1973, Bridgehampton, Dick Smothers, Bob Johnson and Don Yenko, the #49 Corvette ran in 12 & 24-hour enduro races at Daytona, Le Mans and Sebring. At Le Mans, the Traco-engined “show” Stingray was clocked at 215 mph!"
