Your shop must be pretty crowded!

Re: Merry Christmas from NHRA HP adjuster
 

Some of his shops are, others aren?t LOL. John gave me a tour a few years back?I?m still amazed.

Re: Merry Christmas from NHRA HP adjuster
 

I see on the hp adjustments they changed the hp rating on a 68 Corvette 327/325 motor. That's a mistake. They never made that combination in the Corvette. Are they talking the 327/350 stick only combo?

Re: Merry Christmas from NHRA HP adjuster
 

They lowered the 325 hp motor in the Chevelle and Nova, so I would guess that you are correct. In the Corvette the 350hp/327 motor is the same as the other 2 bodys I believe. They just rated it at 350 because it is in the corvette.

Re: Merry Christmas from NHRA HP adjuster
 

Dave is correct. Looking at the blueprint specs on the 327/350 in the Corvette and comparing it to the Nova/Chevelle 327/325 motor it appears they are identical Just the Corvette was rated higher for what ever reason. And yes it is a stick only motor.

Re: Merry Christmas from NHRA HP adjuster
 

Bob,
Through all the 60 years I've been racing I have always heard the Corvette ratings were higher on like combinations because of the Stock Exhaust manifolds and the Stock Pan configuration. For the life of me I can't see how a Exhaust Manifold difference in all classes that allow aftermarket headers is even a consideration for HP variations. Now a Stocker with a Stocker pan.. I can see that there could be a difference...In Super Stock and Super Stock GT where aftermarket pans are allowed I don't see any reason to add HP to "like" engine combinations. Is NHRA Tech going back to some wheelbase considerations like in the old days with Ford and Mopar??
