1995 R 351 balance factor

[ron 1995 r]

Was the balance factor of the 1995 R 351 engine 28.2oz or 0oz?

I see ford offers a M-6009-Z58 engine which is zero balanced
and a M-6009-C392 which is 28.2 balanced.

Was anybody able to tell you yet? I know we have enough R owners here that somebody should know...

28.5 oz is stock. Early 302's were also 28 oz but the later one's were 50 oz.

Zero balance is better for high RPM's. Most race engines are balanced to "0".

You need a zero balance fly wheel and crankshaft dampaner with a zero crank.
