Submitting Parts for NHRA Stock/SS

James L Miller · 09-09-2014, 11:32 AM

Has anyone submitted a part to NHRA for inclusion in the approved parts list? I asked Silvolite to submit their 1266C piston for a 318 for a legal replacement for the early 318 Chrysler engines (1967-1972 or there about). I got a reply that they would send me a piston to submit. I asked if they had a drawing since it looks like NHRA wants a drawing first, but they won't give me a drawing, but gave me a list of specs.

Anyone have any idea of how much it costs? I don't want to spend a lot of money getting someone else's piston approved. The only reason I want the piston approved is the early 318s had four valve notches in the top and the approved ones seem to be all flat tops. It looks like the old TRW/Speed-Pro L2329Fs are long gone.

It should cost you nothing but your time.

Here is the process!

I don't think the 4 valve relief piston will fly with nhra because it will make all the 800-1300$ Approved piston sets obsolete...

There official posted NHRA process always seemed like it was intended for manufacturers to me as opposed to track level racers seeking to get a part on the list. A stock racer I know got a piston approved by sending them one to look over. They sent it back in a torn manila envelope... I'm sure there was a more to the process but CAD drawings and pre production prototypes weren't among them. Call the main office and ask. Then be prepared to call again.

I've reviewed the PDF already and came across this line in Paragraph 2.

"All fees and costs, if any, incurred by NHRA in determining whether to approve or disapprove the proposed changes to vehicle design or vehicle components shall be borne by the party submitting the items for review."

From the old 318s I tore apart years ago, the early ones had the four valve relief pistons. I think as they lowered the piston down the hole, the valve notches weren't needed anymore with the .390" lift cam and tiny duration. I don't think there are many people running the early 2bbl engines. I'm sure the smart guys are running the TQ in the late 1970s 318s. I have a 1969 Barracuda, don't have room for another car. It's an original 340 car, so I don't want to put a roll bar in it, so the 318 should put it in R/SA.

I also sent an e-mail to Tim White per the last line of the PDF.

"To submit a component for approval or for additional information please contact Tim White at twhite@nhra.com"

Thanks for all the info. If I hear from Tim, I'll post the reply.
