"Distance between backing plates may not
be changed. "

Is that the distance of the trailer axle that came from the manufacturer to the sub-contractor?

You are correct there, and there's more that they didn't have to change back from the COPOs

A 9" wouldn't be legal in a 1969 Camaro in Stock Eliminator. So, tell me why your question isn't dumb?

Still not a rule change.

For what it's worth, my 2010 Drag Pak came with instructions that included very clear measurements.

Oh okay. So was rear width the same as the showroom models? You know, lots of backspacing in the wheels?

Mr. Gump , there is a reason they call it stock eliminator. You know, minor details like a Chevy rear end in a Chevy, a Ford rear end in a Ford. NHRA could have done us all a big favor if they just put these CRATE MOTOR cars in Superstock eliminator …..

Ya know M.J. you're right. BUT that's not where the Manufacturers wanted them. And you've got to admit that they sure are popular as there sure are a ton of them out there and being built. I'm sorry to say it but if it weren't for them, we'd be calling ourselves Nostalgia Stock because there's no great rush of Racers building Stock Eliminator Cavaliers, Escorts and Neons.

750-1000 HP cars being factored at 400-550 is pretty accomodating. Look on Jegs website for example. 632 copo motor out of the crate makes 1004 out of the box. The super charged 350's had an NHRA factor of 550-580. Those were well over 1000 out of the box in a crate. I wont even mention how the hoods seem to be getting taller as the cars get newer as well. NHRA has bent over backwards to accomodate these factory cars to make them fit Stock Eliminator. Im just curious if there are any wires hanging off that 9" center section when it comes from the factory.

NHRA could fix that. For a long time Pro Stock had I believe it was a 5 year rule.All NHRA needs to do is add a 40 or 50 year rule for stock. :rolleyes:

Stan
NHRA tried a "20 Year" rule once and it didn't work out very well for them.
