Art161 Posted July 23, 2003 Share Posted July 23, 2003 Olds did not put 455 cu. in. engines in the stock Cutlass/4-4-2 until the 1970 model year. The standard 4-4-2 engine was rated at 365 hp. This same engine was available in the Cutlass Supreme as the W-32 option. The 4-4-2 W-30 engine was rated at 370 hp. For the 1971 model year, the compression ratio was lowered to accommodate unleaded gas. 1970 was the only year for a Cutlass/4-4-2 high compression 455 cu. in. engine.

Grimm Posted July 27, 2003 Share Posted July 27, 2003 According to 442.com's tech page, the best 350 was the '68-70 W-31 engine which had 325 HP. The best 455 was the '68 Hurst with 390 HP. Link to comment Share on other sites More sharing options...
