318 Poly Flow Test

Thanks Earlie A for these tests. Very interesting to say the least. It's true that the Poly was never built as a "performance" engine. However, that doesn't make it an engine with zero potential as some say! In fact, the opposite is the reason I run with one. Also, there are obvious reasons why there are distinct similarities between the Gen3 Hemi head layout and the Poly which have been well-documented.

As to the weight issue, a complete Poly engine is 55 lbs. heavier than an LA engine (depending on the source). Heavier yes but a major issue, No. Yes, I'm Poly-biased. I have a .030" stock bore Poly (.323 CI) with forged pistons, balanced rotating assembly, larger (stainless) valves, ported heads, Full-length headers, Magnuson twin-screw supercharger and a Tremec 5-Speed in my early 65' Dodge D100. I intentionally didn't take the stroker route as it's more fun to tell people it's a 318 Poly that just dusted them!
