Can someone explain to me how a rear wheel drive Chevy cobalt with a small block or LS combo has a home in NHRA superstock, but a 451-powered Dodge or Plymouth B-Body does not?
Nostalgia Super Stock you can run any cubic inch you want. The car just needs to look period correct.
Not that is what we are talking about. Just a FYI.
Not really big buck.Unless you have it to spend. I ran my 65 Belvedere 451 automatic in N/SS-E in St.Louis. It was a 12.00 second class.
The fun part was you run heads up with others in the same class.
Classes/Rules have changed over the years. I think they go from 8.50 up to 13 or 14 second in 1/2 second increments.
I have been away from it for awhile.
I believe in SS Stock one is allowed to be .050 bored over. But stock stroke. So even a 440 would be just a bit short of 451. (I think .060 makes 451?) I looked into it once upon a time. The rulebook got a lot thicker for that class. Here is where shaving mgrams of weight here and there. And building to blue printed quality pays off. It's a car nerd's paradise. Finding ways to legally cheat for lack of a better definition?Yep, super stock GT classes, developed to get late model front driver participation. They allow rear drive conversions, but they have to use nhra legal superstock engine combos, stock bore/stroke dimensions, overbores allowed.
A 451 is a stoker 400, therefore not legal in any super stocker.

My Duster with its SS hood and 451 is in the spirit of the Super Stock of yesteryear. But I already knew it's a non qualified. Even though it has a 74 400 block. Same year as car. Which I believe is one of the requirements. (Or NHRA approved replacement.) Our point is that engine size is just one of many restrictions.You guys are making and missing my point to some extent. The GT classes make just about anything possible with the right car, but a car like mine (or most of ours) that is for all intents and purposes a “stock” type of effort, but simply because of the crankshaft in use (a factory stock piece none the less) isn’t legal. Yet I look at cars like the GT class Cobalts, and there is absolutely NOTHING stock about that combo, yet it is legal and owns its class. Just doesn’t seem right to me.
I wish we had a Nostalgia Superstock group up here in the NW. I’d tailor my car to that class if we had one.
I asked specifically about the 451 Doug, because that’s what I run, and while I’m having a blast running ET brackets, I’d love to have an index class available to try my hand at.
I known this is probably near impossible any where to get pictures of a SS/AH Hemi engine insides?If you've ever looked inside a SS/AH Hemi engine you'd be speechless. Decked .200", lifter bores moved, ports raised, intake face of the head paper thin. Or Eddelbrock heads legal in stock for all makes. You can run a fwd Daytona,Lebaron, in S/S as well. We have lots of Stock Super/Stock associations around the Midwest and East coast that allow N/SS cars. None by you?
