Making everything work together to the Nth degree..plus a ton of R&D on different combos and components..I know of a record setting 360-4bbl F-Body combo that they thrashed for 15+ years to get it where it is today,its fully capable of 1.30+ under the current index of 12.30 in qualifying trim and 100% legal. Depending on the class and combo its not as much money as it is time,time and more time.

Most of those guys have been running Stock for 20 years, a lot of them with the same car. I see them in Ennis and a lot of them are the same car or combo. Mike Cotten has been running green Dusters (I think he's gone between the 340 LC and the 360) for the last 25 years. Vern Buchanan has been running that same Mustang for just as long. I'm sure they have crates of parts at the shop that they tried.

Searching through piles of heads to find the best, searching through piles of intakes to find the best, I have heard of guys running 20 different identicle intakes on a dyno to find as much as 25 hp differance from the best to the worst, that takes a lot of time and money, then they acid port them to open them right up to the max CC and if they go too big then they can mill them the maximum allowable amount to get the CC back down. Some of them will dyno test cams changeing only one timing event per cam to find the best intake closeing point, the best intake opening point, the best exhaust opening point and the best exhaust closeing point since lift is limited. They will change things mabey two degrees at a time to find the 4 absolute best possible points. The guys running hydraulic cams will fool with the lifters to make them basically a solid so they can turn a few more RPM. Also you better beleive they are looking to move the cylinder walls away from the intake valves, they will play around with valve jobs to get the absolute highest flow, some of them beleive in indexing the plugs while some guys swear there is no differance. Then they move on to the trans and find the lightest parts they can find, and make sure everything is lined up perfectly to reduce friction and in an auto they make the trans shift very fast with the absolute minimum line preasure they can get away with because high preasure takes away hp, then they make sure the u-joints are in prefect alighnment to reduce power robbing miss-alighnment, in the rear they make everything line up perfect to re-duce friction. Drum brakes are gonna be adjusted to not cause any drag at all. Suspension components are gonna be blue printed to allow just right amounts of front end lift yet keep the front down low to reduce drag. Alighnments are set to perfection to let the car roll easiest under power... nothing is left to chance everything is checked and re-checked like you wouldn't beleive. The guys who say it is just time and not so much money just have a different perspective on what money really is.

hi, I'd like to clarify couple misquotes, first, the cam can be any duration, stock lift required. second,a pan evac system is not allowed or vac pumps either. it does take money, however, lots of work and effort. you have to think outside the box, so to speak. hot rod mag and internet do not build stockers. its true, not all castings are equal!!

A good Stock racer from the area told me once, "Rules are written in black and white, a good racer finds the grey area."  Jason Lines family lives eats and breaths Stock Eliminator racing. Mom, Dad, Brothers, and cousins, all run Stock. It's ALL they do period. Now another thing to consider, alot has changed over the years of running stock. aftermarket disc brakes are legal, and SOME aftermarket heads are legal also. The heads on Lance Lines CJ 69 Mustang NEVER came on a production car...

As already said if your not experimenting on your combination your getting left behind 
Bottom line is how hard are you willing to work and how much money do you want (can or willing)to spend
