Had Rhodes lifters and 273 adjustable rocker arms. With some pencil neck pushrods compared to todays. Those good old days when tuning was an art and records were set.

Paul you have me laughing, you would never see 7000 rpm with one of GK's cam's ... those we came up with were low RPM with lots of torque - 6200... maybe 6400 rpm... living with stocks springs was a treat. The Chrysler specs that were turned in for the 340's and 360's were a treat to work with after working with the limited spec's on the chevrolets.

I shifted my ‘56 Chevy “Jr Stocker @7500. About the same at the finish line. The factory springs, on the seat at Stock specs (79 lbs) were weak open. I discovered PAC (?) springs, still needed new springs each race. The cam looked like a roller cam, with those nearly square lobes. Red Anderson shook his head at cam check time during tear downs. Not difficult to change the springs with the heads on the engine. TRW springs, out of the box, checked much better than GM springs. The better springs may have been Comp or Lunati. I can’t remember names well since I got so old. I apologize for that.
