Crank for SBF SS/GT?

FireSale · 02-19-2014, 02:13 PM

There seems to be a distortion field between the NHRA rulebook and the Accepted Products guide that either encourages cheating or discourages racing, I'm not sure which.

I was going to go with an Eagle or Scat rotating assembly to build the 302 for my SSGT 68 Mustang but I wasn't sure all the parts they included fit the NHRA specs so I'm going to put it together myself. Pistons I can figure out, Flat top with two notches that don't increase stock compression. OK. Rods. 5.090, no fancy stuff to make them light. OK.

Here's the problem: The rules state OEM or NHRA approved crank only for SS, which carries over to SSGT. When I go to the Approved Products guide, there is a grand total of ONE crank to pick from on a document titled Stock Eliminator Approved Cranks. Is every SBF in SS out there running this crank or am I missing something?

Me thinks I'm missing something...

My instinct tells me I can run any crank with the following dimensions as long as it isn't under stock weight or had voodoo specifically lined out in the rules done to it.

3.00 Stroke
Rod bearing journal: 2.123
Main bearing journal: 2.249

Thanks,

Dale
