Does this question imply that NHRA won't approve a crankshaft for a Pontiac?

Called Callies and spoke to someone familiar with S/SS who told me the company had no interest in making cranks that could be approved it would mean a new line and inventory with very limited sales. Was warned that is how they would react by my buddy who bought many cranks from them over the years.

Years later the Callies crank on the list showed up can only assume an engine builder with good relations had the crank made and approved. Never personally checked to see if there actually was any inventory because was working with Scat who had a 1 piece seal crank approved on the list.

After 2 years of trying to get Scat to do the process, another case of "is the effort worth the potential business" called and purchased a crank to ship to NHRA, went through the process which was pretty simple it's on the list.

If someone wanted to go through the process of getting a Pontiac crank approved spending all the time and money you probably will be successful.

Frank,
I went thru this process to get the Callies crank approved. Dwayne Boes from Callies brought several cranks to Bruce Batchelder in 2015 and the 305/350 was approved.

Rod, does this Callies part number come with the legal extra .013 stroke or is that an option?

Thanks Alan,


I guess the next questions are, which is better new trick of the week crank or an old STOCK unmodified crank with the extra .013 stroke?
