Not to hijack this post, but one of the posts above insinuates that Budd frames were heavy duty - From all of my research, I was under the impression that the three frame suppliers: A.O. Smith, Flint Frames and Budd, supplied the same type of frame. They were all the same. Can anybody comment on this? If Budd did make a heavier duty frame, what was different about it?

Thanks

Hi Rob:
I will let the experts comment but I have never seen any major differences.It seemed the manufacturer of your frame was determined based on the location of where your car was built. I have taken Budd frames out of 6 cylinder cars and we have two in our 427 cars.Have to love the SO cal ones.

That's how I understood it too. Jon Krogh also told me the same thing... And he has taken apart scores of cars. You never know though...

That's my personal "i.e." reference after Heavy Duty that I believe Chevrolet really used in that situation back then.
Of the few heavy duty suspensions I have seen in person on any GM B-body,Buick-Olds-Pontiac-Chevrolet,all have had Budd frames.
I can't find it right now,but somewhere I have a internal product bulletin stating Chevrolet preferred to use that manufacturers frames when special heavy duty suspensions were requested before assembly.
It when on to say because Budd used a heavier gauge steel on it's one piece tunnel bottom & welded on channel rails then other similar frame manufacturers at that time,GM preferred to use them more in case of warranty issues.
I think Parish Pressed Steel later on adapted to this design as well..

Hi Rick:
Be careful now you are crossing into that B body dark side. If you say there was a letter there was just that it does not seem GM followed it on B body.They increased frame guage in 1966 for sure after having warranty issues in 65 this was enforced by all frame manufacturers.I have 6 frames right now as samples all BB cars, 5 of 6 were 4 piston disc brake cars and all had heavy duty suspension two with F41.
In this mix 4 Budd and 2 AO. I have blasted one of each and and seen no difference in welds nothing.The boys talked about this some also on the impala site. Would be interesting to prove.

If I remember correctly, in '67 they went to a full boxed frame vs. the open 'C' channel that they used in '66 or '65. Full boxed under the rocker panel that is...
