Head bolt.jpg

Does anyone have (2) 7/16 x 14 thread x 4-1/8 inch head bolts like this to attach a/c compressor bracket on a 455? Top portion needs to be 7/16 by 1-1/4 inch long.

 

I have some; e-mail me: drolds1@bellsouth.net. Thnks, Bob.

 

If he doesn't,I do.You should have 2 on the passenger side,and 1 on the driver's side.

 

If all else fails, these guys are great:

I am rebuilding my 455 now, and I also need 3 of these head bolts.. (If I remember correct, they are all 3 the same...) I looked all thru the ARP catalog & the AMK Products with no luck. It can't be this hard to get some new ones... Can it ?!?

 

If you went with new or aftermarket,you would have to get a long ARP stud,with enough material to fasten with a nut,and have plenty sticking up beyond the nut.Your typical Olds 455 ARP head studs only have a few threads sticking up,if that much,when all is fastened down,so those won't work.
The 3 standoff studs are for the alternator bracket,compressor bracket,and the heat stove assembly.
