O-320 cylinder spacing

sblack · #1 01-30-2017, 10:35 AM

Does anyone have a dimensioned drawing that shows the distance between the centers of the cylinders on an O-320? I am making a split plenum and that dimension would make it easier to fabri-cobble the inner baffle wall which will go against the lower cylinder barrel fins. I could just rough measure it, but knowing the real value will make it easier.

Measured mine with dial calipers. Looks like 7.125" centerline of the cylinders.

I got a scaled 7.07 as a quick check in my TurboCAD

thanks guys. Probably good enough for my needs. I will make my parts out of a cornflakes box and adjust as required before killing good metal.

cheers
