Hello All -
My 1969 Firebird went in the shop (initially low priority) over 7 months ago. The shop decided to get it back together installing new cam, rocker arms, and lifters. The shop noticed that some of the rocker arm studs were messed up and were going to replace them, but discovered the studs are screw-on instead of press-on studs. The Firebird was originally presented as a 400, but I discovered right before buying the car that the motor was a 1965 389ci out of a Bonneville class car. The shop says the casting numbers on the heads seem to be consistent with the motor, but they just cannot find the right screw-on studs to put the motor back together. For lack of any other ideas, they are going to just order in some big block Chevy screw-on studs and see if they work. Does anyone have any idea why the shop may be having a rough time? Are there Pontiac options that may have been used in the day that they just don't know about? Thanks in advance for any tips.
