67 390 hsp w/AC valve cover bolt size please....

[John R.]

Can someone tell me the size of the valve cover bolts on a 67 390 hsp engine. Anything special about the bolts for an AC car?

If you have a radio the bolts that hold the ground straps from the spark plug wires are longer and unpainted. Also the foward ground strap for the spark plug wire on the passinger side is moved back to the second one back. It's all shown in the AIM under RPO U69.

John -

They're 1/4"-20 (7/16" hex head); nothing special about the bolts on an A/C car.
