The rockers are 1979, and hand made. They're pretty crude with machine-tool marks. If completely disassembled, I'm sure there's lots of surprises. It's complete, from carbs to dry-sump tank.
Mr. Glidden is the GOAT of prostock.
So cool! Pretty wild you have that motor. He was the greatest, no doubt, just a brilliant and driven guy. Not many out there like him in any walk of life let alone drag racing.
Just to get this straight - he was re-engineering cast-iron cylinder head chambers and ports including altering the as-cast valve angles AND making his own rocker arms by himself. Jeez!
Any clue what the rocker ratio or offset could be? Are the valves real long? Wonder what he thought of the old Poly 319 holdover 59 degree lifter angle.
