Sounds like "Cross Breeding" to me! Specifically stated in the rule book for Super Stock and Stock.

Illegal for Stock, but in SS you can run any intake as long the carb is located in the OEM position. You also adapt any intakes with spacers. The Smith brothers (Pro Trans), ran a Chevy intake, with adapters, in the SS 383/Cuda for many years.

We arent talking about the intake, we are talking about the reason why you need the 383 intake. Arent they using a 400 block instead of a 440 block taking about 0.800 inches off the piston height? Isnt that the definition of cross breeding?

Pontiac made a 9.200 deck block that with a 400 we could do a very small crank and a very small piston skirt. We were told that is illegal. Several SBC guys I know say they are going to build a short deck 400 since their rods are like 5.35 inches. Wouldnt that be a killer combo too? Did NHRA allow that?

I dont blame the BBM guys for doing it, it is just that if one group gets it then everyone should. I could only do about 0.200, but a 428 could do about .400, and a 400 could do about 0.750.

Hell, a blind man can tell a 440 block from a 400 block.

Rocket, I assume your talking about stock. If the stock rod length is used and main diameter is same, a 400 block as a 440 is proper reading of the rule book to me for SS.

Did you read the specifications provided to you? Did you read the part about engine families? Did you read the rules violations? Go back over those items and then get back with your interpretation. Thank you.

Chris we know each other from 20 years ago. Dont give to much info as soon as Rocket tells his real name Ill chime back in. He is in left field. And yes a Ray Charles could tell the difference between the two blocks. Can you Rocket without tools just your eyes.

Herb, Dad says to tell you and your Dad hello.

My mention of the 383 intake did what I wanted it to.Ray Charles will build my next engine.

Ray would feel around for the 1" x 2" machined pad cast into the block on the driver side between the deck and intake manifold. It is flat and faces straight up. Since I have eyes that see, I would just look in that direction. The factory marked this block pad with designations such as "HP" if it was a magnum engine. Sometimes you'll see a maltese cross that indicates non standard bearings or bore size from the factory. Sometimes the pad is blank. But this pad is only seen on the RB family and not the B family engine. Since your dad is in most of the old Direct Connection books he should be able to confirm to you that the B engine and RB engine are two distinct families as defined by Chrysler. These two families do not allow the interchanging of crankshafts, connecting rods, pistons, pushrods, or intake manifolds. . Hope I didn't leave anything out.
Herb, why would my name ad credibility to this subject? The material facts are right so there's no need for a debate. The rule book is clear on these material matters so there's no need for debate. The only room for debate is if NHRA should enforce this rule and if not, allow others to have the same advantages.

So I'm in left field? Which field are you in?

Not to change the subject,but I was wondering if it is legal to put a Dana rear end in an AMC Stocker?

The problem with you is you do not race in stock or superstock. By your posts here and everywhere it's obvious you do not have an understanding on the issues racers in this class must deal with. The rules will not "dumb down" to your level one day so you can jump in and race stock. So get over it. Since you have a grudge against me, start your own thread. Just quit mudding up everybody's discussions on things you obviously know nothing about. Tell you what, for $100 I will send you the letter from NHRA stating a Dana 60 is legal for use on AMC's in Stock. I'll even frame it for you.
