9 to 1 Piston for EQ 62cc Head
ok, so the 405 has a different pin height, lowering the piston..... i didn't check all the numbers, thanks....but that's what i want is tight quench top and bottom with fuel mixture compressed only into the chamber. that's what is making these modern LS , Hemi,ect..... make power. "The keys are heads with quick-burn combustion chambers, optimal quench achieved with near-zero deck heights, an aggressive cam ground to Brandes’ specs, and careful carburetor and ignition tuning.Brandes explains, “I try to achieve around 0.040-inch quench. That’s about what a modern LS-series motor has. Spark-plug positioning in the chamber, slightly biased toward the exhaust valve, is also critical."Article i found in Hot Rod Magazine. ( my old Street Stock Barracuda W-2 360,was fast... my 2nd year wasn't that good, i just do Hobby Stocks with my Kids now)
