3sp to 4sp manual
 

I would like to run a stick in an older stocker combination that was offered with an auto or 3sp manual only. We attended a S/SS event in september and several racers told me NHRA now allows an upgrade to a 4sp for the older cars. Is this true? Can you use a hydraulic throw out bearing also?

I have been out of racing for 20 yrs...things sure have changed!!

Re: 3sp to 4sp manual
 

Unless it came with hydraulic, it is not allowed. With a performance clutch a mechanical linkage is best for consistant air gap settings.

For the trans, straight out of the rulebook, "OEM or NHRA accepted aftermarket transmissions having same number of forward speeds (O.D. gear not required) as original, and reverse, may be used."

This is where it is a grey area, as cars originally with power glides can now have 3 speed automatics, per the rulebook

For clarification on the trans contact your local tech director, as it is not black and white for a manual trans like it is with the auto in the rulebook.

I see that you are new here. Please allow me to offer a polite, gentle suggestion.

There is a historical vehicle that has been raced in NHRA and IHRA stock eliminator for decades called the “Gray Ghost” . It was, of all things, a Corvair built by Tom Gould.

Tom resides in this forum and is deeply respected for his bravery and intellect for racing a vehicle that most people didn’t have the courage or brains to race.

In deference and respect to Tom, you may want to change your username.

Hey bunkster go back under the rock you came out from under.It's none of your business what name anyone here uses. Mr Gould doesn't have a copyright on the name of his car. The OP said he's been away from racing 20 years ago. He's no nubie.
Go over to Yellow Bullet if you want to rub it in peoples butts. You started it in the deep staging thread now you're doing it here.
Kenny if I'm wrong tell me so.

Mickey, it's hard not being nice when trolls come here and try to tell people what they should think and express themselves.
Y'all have a Merry Christmas Mickey.

Dwight,
Isn't a guy from "Noo Joysee" saying "Ya'll" an abomination to all us "Folk" in Arkansas?
This is the proper salutation:
Ya'll "DO" have a Merry Christmas

Yes you can replace the 3sp manual with a 4sp manual in stock along with SS. So if you have a 265, 6Cyl comet or 6Cyl Nova you can run a 4 speed. Also for PG optioned stockers and SS can run three speed autos. The above mentioned combo's were just examples. Hope this helps.
