I would imagine at a swap meet or maybe someone has one for loan? Its obsolete and over 40 years old. 1971 was the last of the 7 inch wide tire days. Maybe a 1985 version would be eaiser to find? That was the last year that cams had to check on factory spec. and spring pressures had to be factory.

Tear downs were fun. Red Anderson made some very slick tools for checking cams, etc.
Great guy. I still miss him. R.I.P.

I still have some of the slick tools Red made. The really trick piece is the 2 ring degree wheel to check overlap and duration. Sadly they just collect dust in my tools box. Red was a great guy and very smart.

Pure Stock is what Stock was before the Unlimited Springs, unlimited cam duration and Mandatory high test fuel and roll bars. From1974 to around 1990.

The IHRA Rules book is very well written. Read carefully.
Most of the rules are simple bolt-ons.
Tires, shocks, traction bars, headers with mufflers.
The three key areas are good set of gears, good converter w/ beefed tranny, blueprinted cam with stock springs.

I like John at Bullet Cams.
He will build you a cam that will pass and send the right springs.
Suggest if you have the engine rebuilt go to a master engine builder who knows the stocker rules. Cost will be near identical to a normal rebuild from a normal engine builder. The advantage is knowing that the block and heads are spot on.

The suggestion to call Mike Baker is also a good start to confirm what is a proper fit for your car.
