Were all on the same team here. Its a real shame it has to come down to needing dyno slips for proof.

 

Thats very interesting. Please give us more details on these cars you are talking about! any websites or details?

 

My friend ran his stock class 85 Camaro in K/SA in 2001 and was regularly in the top 5 on the qualifying ladder at any event he attended. As a K car, he ran it with the TPI version of the 305.
This year he chose to reduce his racing calender a bunch due to his upcoming marriage in Oct.
This season also saw a switch back to the carb version in mid summer. I was hoping to post a link to some qual results in div 1 events from 2001 but NHRA has since deleted those links from there site as has the NHRAdiv1 site. Only stuff up there is from his carb combo, however an early shutdown qualifying run from E-towns nat'l event in May shows a 12.039. This combo is much faster than this but you would need to understand how NHRA's Automatic Horsepower Factor System works to fully appreciate why guys will lift early to scrub et off.
In stock class you are restricted heavily on what you can and can't do to the cars and motors. He runs an aftermarket injection software setup. No porting of either the heads or intake (base, plenum, etc) is allowed. Cams are allowed to use any duration but are restricted to stock lift. Pistons and rods must be approved part numbers and be no lighter than the original pieces. Cranks must be stock with no stroking. Blueprinting of all specs is allowed. Generally he ran within a tenth or so of the sister car which is a carb combo. You will find that car on most of the links on the div 1 site under the div 1 results link. Go to http://www.nhradiv1.com and click the results link on the left of that page to find it. Look for Bob Horgan, that is the team car to my friends car. As I said, I won't tell you things like shift points as this type of info is not for general knowledge but are within a hundred or so of the carb combo. I ran their test motor in my car at Epping this year even though I don't have my car as well suited to the 305 as it is to my 400 street motor. Even with a bad set up (wrong conv,stock low gear in trans, wrong rear gear, etc) it still went decent.

 

mod133 I can't seem to find what you are refering to.
the results link just showed me some top fuel dragster races.
This K/SA class sounds interesting though, can you point to where I can see all the rules? Basic info on the cars involved, etc?

 

For the E-town nat'ls link use : http://www.nhra.com/2002/events/race...riday_stk.html

I'm not sure if the rulebook info is listed online anywhere. The classification guides and engine blueprinting spread sheets are linked from the Lucas Oil series home page on NHRA's site. They are confusing though if you're not familiar with what you're looking for. The 3rd gen's fit several classes depending on year claimed and motor combo used. Currently the 85-87's fit H-K, the later Z28's & Iroc's fit M-O, the v6 cars go in V, etc. I believe that with the next hp increase to the 305/165 combo the 85-87's will go to G-J classes due to the refactorring. The adjustments in hp are what I was refering to with the AHFS deal. Also,with the recent splitting of fuel injector cars from carb cars from 86 and up the later tpi cars will now be in the new fi classes just created.
Would suggest you try to get to a national or divisional event to see these cars in action. The qual sheets won't list the actual motor combo being used, only the cubes. It's not as easy as it sounds nor as many think it is to build a fast class car. Get an IHRA or NHRA rulebook and read thru the rules for stock, NHRA's is a lot more thorough though as IHRA uses a lot of NHRA's rules.

 

Ah...maybe I missed something in the post, but aren't we talking about a production car? built by Gm to be sold to the public? I guess we just jumped into Super stock?

Come on GUy we all know that any motor can be made to Haul A** with the right racing equipment. I have see a NON-turbo Buick Regal without THE JUICE run 10.20 with a 3.8

And the guys were pissed, that it didn't go 9's....Of course you are talking about 14.1 compression huge came trans brake 5000rpm stall weight reduction. all that.

I cannot remeber the name of the class...but there has been several 305 TPI car the have gone 11's.... I just know that under these rules....factory lift on cam cannot be changed and short block must remain factory....

But compression thru Factory head porting or milling, valve train and inductioin can change. Of course gears and stall converters...race suspension that kind of stuff is allowed.

usually these cars have lower MPH trap speed but the come out STRONG!!

MONEY AND KNOWLEDGE CAN GET YOU ANYTHING!!!

BUt the General Never made any bad a** 305...

Gale Banks DID!!!

 

S. Holley,
No reference to juiced, hot compression or super stock cars was mentioned. The class referred to Stock eliminator. That means no porting, no trans brakes, use only the specs on the spread sheets that were submitted by Chevrolet to NHRA and 9" wide slicks. Of course you could port the intake and heads but that will get you a dismissal slip from the event once caught and in right circumstances get you a year off from racing in their sandbox. It's a lot harder to go fast with these restricted cars than you think. But it does show you what these motors are capable of with attention to details and a well sorted chassis.

 

Is this class comparable to the 'factory stock' class the ford guys race in?
