Volumetric Efficiency

Post by MaxKlinger »

Anybody know what a stock 360 FE is rated at in terms of volumetric efficiency?

Probably around 60%.

Really? That low? I was thinking it would be in the 77-83% range.

Would going to an aftermarket intake manifold improve VE?

Ve is typically advertized at peak HP. A 360 is likely more efficient below 2500 RPM than most carb engines whereas it sucks at 4000 RPM peak HP ratings.
