Just ask any high performance engine rebuilder. A Demon Tech once told me a 750 Mighty Demon (DP carb, which I run) would flow 900+ cfm on Holleys flow bench. It’s quality that stands the test of time. 22551660 - 4.00'-4.190' bore, 4-bolt splayed steel main caps, Chevy / Olds 'Rocket' block, 400 main journal, wet sump, raised cam, 2-piece rear seal, 9. a 650 VS would be fine for a 350.but just a warning, Demon Carbs are wet flow rated Vs. Over 2,000 hours of lab testing and a season of late model NASCAR testing proved the High Performance Bearing was up to the test. This characteristic is especially important during start-up because oil does not reach all critical components immediately. Generally, for a stock 350 Chevy engine, a camshaft with lift in the range of 0.420 to 0.450 and duration in the range of 200 to 220 degrees at 0. The primary advantage is that bearings with FLUOROPOLYMER Composite Coating retain engine oil on the surface, even under extreme heat and pressure conditions.īeing a lubricant itself, the coating provides secondary (back-up) lubrication in the event that momentary oil starvation occurs. This dry lubricant actually penetrates the surface where it has been applied.
This hard and high strength condition provides the “toughness” needed for racing applications. By leaving the structure as cast, tensile strength is almost doubled over the standard bearing. Grain-Controlled Babbit: By cooling the Babbitt quickly in the casting process, very fine grain structure is achieved.
