Anybody ever do this? How hard is it/what would a machine shop charge?
I want to go turbo with a '69 390 but the 7/16" bolts are a bit on the small side.
Thanx in advance!!!

Yes, their is enough meat left to do this. What the charge would be I do not know

I did it a long time ago it was a pain but it worked probably not worth paying a shop to do it but that is going to be your $$$
