Looks can be deceiving when it comes to "stock" engines....Back in the old days at Dover Drag Strip we called them "mountain motors"...there was always a little more to them than met the eye [img]<<GRAEMLIN_URL>>/naughty.gif[/img]

Mountain Motors was/is a term used for IHRA Pro Stock racing. 850 cubic inches of whatever.
Usually the Fords got the most cubes out of their stuff. The Mountain Motor Nationals at MIR. Fun to watch. Most could not qualify at an NHRA Pro Stock event. Stock eliminator as of I guess last year can run roller rockers. Acid porting the heads have been around a long time to. Next Stocker you look at, see how much flange there is on the head where the headers are bolted to. Camshafts, same stock factory lift but the duration could go on for minutes. I remember John Guilus did a 327/340 motor for Abbazia Bros. in their 62 E/S vette a few years back. Saw the car run 10.40's in good weateher allday long. NHRA factored him to death after that. AFB carb too. |

There are so many more aspects to make a Stock Eliminator go fast than just the engine.
Right now, I am learning how to tune a Q-jet. First you buy a carb built by one of the handful of gurus. Then, you spend countless passes swapping primary jets and metering rods, secondary metering rods, secondary rod hangers, adjusting secondary air valve opening, etc... Besides the engine, there is the transmission with the right gears and the correct converter for "your" engine. You have to figure out the right gear ratio for the differential. Do you run short or tall slicks? Did you pick the perfect shocks for your combination? The list goes on and on... Most of the guys who run fast have spent countless hours tuning and testing their car. How many of you guys know how to read a spark plug for the correct fuel mixture and heat range? I'm willing to bet not many. This is my first season Class racing and I am totally overwhelmed. My house and my friends have all taken a backseat due to the number of hours I have invested setting up the car. I am one of the lucky ones, as the Super Stock racer, who own the performance shop that I deal with, has taken me under his wing. If I were doing this on my own, I either would not be as far along as I am now or I would have already packed it in and gone back to bracket racing my 2000 SS.

All you need to do is go buy a new:
COPO Mustang Drag Pack and you are an instant Stock/SuperStock racer. NO flogging, no real test and tune. Complete and ready to go. |

The difference between these newer computer controlled cars and the older carbureted (sp?) versions is that the new cars are tuned with a laptop. However, you will still need a laptop for the older cars as, if you are not running some form of data logger, you will never figure out where the cars' shortcomings are.

Pretty fast right off the Assembly line. If you are a good computer guy you can dial them in pretty good.
Those guys do share info with each other. |

The slow guys in MMPS would just dominate the 500's if they ran together. Our buddy had some issues and didn't qualify, EFI issues MAYBE. BUT have WON a number of MMPS events. If you look at the winners at say last NHRA and MMPS events, 500 win with a 6.62 but MMPS won with a 6.31. But without a doubt, the NHRA 500 motors are the ELITE of N/A motors. We do have a friend who did just get a "GOOD" motor from the guys at ELITE infact. And even though the S or S/S stuff can run, like AA/HA Hemi's, the 500's are still the undisputed kings of N/A, searching for every hundredth, racing.
