The "STOCKER" grinds are usually custom ground and not "Off The Shelf" items or in a catalog. You have to call a company like Comp Cams and talk to Chris Pagent (speling?) and see what he can come up with for your car and engine. The other problem is the Detroit Manufacturers have stopped supplying NHRA and IHRA with duration and overlap spec. for the last several years along with spring pressure specs since the cam and spring rule was changed in 1985. The class was originally intended for the older style stockers that IHRA still has specs for such as 1949 Olds, 55-57 Chevys, 389 Pontiacs, 348 and 409 Chevys, etc.In other words it seems you would be able to use a current "stocker" grind and get away with it although they really suck as a street cam (no vacum). You should call Mike Baker (tech director) at IHRA for conformation of what Im posting on this site to be sure. Its been about 8 years since I have worked with the assoc. He's a good guy and will work with you and your combination. Danny Waters Sr.or Hank Blankenship are also good guys who would help out. Hank is the guy you would probably end up dealing with IF you had to go to tear down (yes it happens on occasion) to be certified as legal. You can also get the engine specs from them to give you what you need to know for the head C.C.'s, deck height, valve size and etc. Good luck.

It sounds like your car may be close to being legal for Pure Stock. D/PS has an index of 13.10 and your car would have to weigh 3470 lbs according to the NHRA HP rating of 300.

Tweaker, don't get discouraged, find someone running the class you want to run and ask questions, my daughter got her 2007 Mustang to run 12:25 with minimum ( legal)work, headers from Roush, 4:10 posi, Drive shaft safety hoop, 15"x 9" Bogart wheels, 9" slicks, reprogram computer(You need someone who knows how to set it up) and removal of excess weight. You must follow IHRA guide but I know once you have the right information your car will run properly. Good luck

you know what that may be where i belong i'll call ihra folks perhaps they'll let me run in it even though i have the louvers and grille i mean that is pretty lame if i cant because of that and my control arms are non-adjustable streetable steeda control arms nothing crazy or fancy besides that it sounds like i would be pure stock i mean my cold air intake is nothing crazy either its just a C&L plastic elbow w/ a K&N air filter on it on it. thanks ill look into it.

Can you run ET Fronts and ET streets in Pure Stock though?

omfg, another bullet in my journey... i read in the rule book it talks about only factory tint on windows in pure stock, wtf I live in florida. I have 15% tint on my side windows and rear window.. these rules are RETARDED. They need to be updated from the 1960's and update to 2009.

I think you need to have 2 cars. One for the street and one for class racing. Rules are rules and the tinted window deal is so the starter can SEE YOU and make sure you have your helmet on and seat belts fastened. Other classes require a window net and a full face helmet so again the starter needs to be able to look inside the car before the tree is activated. Its not about 1960 vs 2009. Also if the car runs quicker than 11.50 or is required to have a LEGAL roll bar you will also be required to have current dated (within 2 years) SFI approved 5 point harness belts. The OEM seat belts wont cut it. I have noticed that most (not all) younger guys seem to think the rules are lame or retarded and the associations should change the rules to suit them. Welcome to the real world.

I understand the rules I mean if you get your car tech'd and inspected when u come into the track they see if you have the proper equipment so the tint is kinda void. You can run tint at tracks on regular bracket races but i guess national type races are even more tight on rules.. Yeah eventually I'm getting a truck to be my primary vehicle when funds permit. Owell. So i guess im screwed since i have tint and all the classes require no tint! lol

Well believe it or not.....I have seen some guys come to the starting line WITHOUT a helmet even in the car. Some have tried to run with their seat belts unfastened or the window net down on cars that require a full roll cage. It does happen from time to time mostly from being in a hurry to race and not miss a round which means a DQ.. Thats why the starter needs to see that you are using the required safety equpment before ativating the tree. Just having it during teching in dosent mean much. A lot goes on in bracket racing that shouldnt happen (not saying you would do it). I see a lot of bracket cars without a fire wall between the fuel tank/cell and the driver and 5+ gals of gas plus a battery just hanging by a thread right next to the fuel cell. Thats because the tracks just want your entry fee and a lot of local so called tech people just dont care. The NHRA and IHRA tech people DO care about your safety. After 22+ years at this silly game I have seen just about anything and everything. Be safe first and enjoy. Its a great hobby.
