Those helmets weighted a ton , almost positive you will ever fusion surgery after years of use . Not sure America has the strength and drive it had a the era of this photo .
I had one just like the one over the cab. My 2nd car, 289 w/sidedraft stromberg. 3 on the tree (converted to floor shift), W/ overdrive and hill holder clutch. Could beat most any stock 55-56-57 Ford or Chevy. Paid $75.00 for it.
