If you read National Dragster, this is interesting S/SS!

I'll leave the name out, but Drag Pak Tops Houston Field! Did anyone who read this article find anything striking, or should I say, just wrong??? OK, if not, here's what I read:

A 2008 Drag Pak Challenger with a 12 year old motor running SS/KA! Hmmmmmm! With tech at the races concentrating on making sure you're claiming the correct year car, fresh air/no fresh air engine and hood, etc. how did this slip by????

Super Stock is supposed to be same year engine combo as the car claimed! So how can you run Top Stock 12 years ago with the motor you're running in an 08 car in SS/KA?

Obviously you are talking about my car. The motor is indeed about 12 years old and it was my Top Stock motor which was the model for the 360 Drag Pak motor. It has been upgraded to 2009 DP Specs and has been down and I can assure you it is quite legal and belongs in the car. I also have one that came with the DP new, and the block is a 2007 Block, as are all the (3) 360 DP motors. What am I missing here? I am actually quite proud of my old piece. The heads have been replaced, the manifold (which Wilson made for me in 2005) has EFI bungs added (it is SS after all), and all the other stuff. But we have run the motor for 12 years, and in Top Stock configuration it ran a best of 9.52 @ 138 mph in my Duster. The Duster also ran the motor for a few years in GT/FA. I think it ran a best of 9.80's in that configuration. Last year we noticed that it was leaking oil out of both headers, so we gave it a set of pistons for the first time in 8 years. Anything else?

I was just quite curious how a 12 year old motor could be claimed as an 08 to run SS/KA? There seems to be an aweful lot of interest by NHRA to make sure everyone is claiming the correct years for the class they are running. Found it kind of amusing that a National Dragster article stated this. I just thought that they would check numbers on blocks/heads, etc. to make sure we were "legal."

This is Bryan, by the way. Tim left himself logged on!! LOL.

When I was researching my build the D6 tech told me the year of the block wasn't all that important as long as the specs were year correct. Heads were a different animal.

Blocks - no, Heads - yes

If you ran a 9.52 in ANYTHING stock , I'd love to see those incredibly "liberal" IHRA rules.

You run a 12 year old engine BLOCK in a 08 car the same way you run a bowtie block or ford or mopar perf block, does'nt matter what year block it is,it's what inside of it that matters,does'nt matter what year heads as long as right casting #

Top Stock quickly evolved away from its original intent, and eventually went away. With everything that's allowed in Stock today, calling IHRA rules (particularly those for a specialty shootout class that doesn't even exist anymore) "liberal" is a little disingenuous.

If you haven't noticed, there are NHRA Stockers running 8.50's.

If memory serves me at all, the final rules in Top Stock for the 360 Mopar, which was a crate motor, was about 13 to 1 compression, .600 cam (still the cam we use) hydraulic rollers (which we still use), Edlebrock heads and we were allowed the runner volume for a Bow Tie, any cast manifold, an 850 race carb, any springs, 9 inch tires and we were about 2900 lbs with the driver. The DP motor uses the 847 Mopar heads (knock off of the Edlebrock), we lost the domes on the pistons (about 11 to one) , we have .490 lift in Stock, we now have roller rockers in stock, (still using the same ones), and of course much smaller runners than the Bow Tie heads, and the pistons are 100 grams heavier than Top Stock for Stock Eliminator, in Stock uses a stock M1 manifold which has been around for years). It's not as good as an Edlebrock. And of course EFI. There will be a test tomorrow on this, so study for it. One interesting thing on this whole mess, when the 360 specs were listed, we took the old motor, machined the domes off, sent the manifold back to Wilson for EFI bungs, changed the heads and made it a GT motor. Put the thing on the dyno, fair, so at the end we threw the 850 Quick Fuel back on the thing. Made about 15 more hp. Called Wilson, and found out the carb will peak higher because of the atomizing fuel in the venturi as opposed to the injector at the base of the manifold. When Nascar went to EFI, the injectors are just under the throttle body. Interesting.

NHRA does require block casting numbers from the OEM for Stock / SS replacement approval.
