Stock Eliminator racing set up
Thought I'd post a quote from Darin Morgan with a little insight to what all is involved in making a car go fast with a little quadrajet carb, "stock" heads, stock engine, and everything else that goes on in the mix. There is a great running thread discussing this over at bracket talk.
Per Darin Morgan:
"How do they run that fast? It’s not easy even once you know how! Some of these guys spend a DECADE or more running the same car and figuring it out. I have seen the same cars running with the same drivers for 30years! Every little wiggle, shimmy, bump or movement that car makes these guys can tell you from the seat of there pants. They spend all there time finessing every little detail on or in that car. At least the fastest ones do. Every single bearing, gear, ring, wrist pin and component is obsessively finessed to reduce friction, increase seal or both. Static ring tension? What static ring tension! They seal the rings dynamically in milliseconds with gas pressure just like Comp or Pro Stock guys do. If you turn one of those engines over quickly with no valve train on it will actually coast a full revolution before it stops. The guys who really know how to reduce friction and still make the engine seal up are scientists of cylinder wall and pistons ring metallurgy. Now to the cylinder heads. Oh boy, where do I start? Let’s put it this way. I stopped doing those years ago because they are so labor intensive and time consuming. I have spent over three months of porting and dyno work on one set of SS/ heads. How do you possibly come out on that? You simply can’t charge enough to do them. I have less time in a set of comp eliminator heads than I eve did in a set of SS/ heads! If you do SS/ heads you do it because you love it not because you want to make money at it. There is one set of Pontiac 455 SD heads I did in 1991 that are still in use today. They have come back over the years for updates but they are the same exact heads. It took months of labor over years of working on them to find out how to design the port in those heads so they made the most power. To say it’s not an easy task is an understatement. You must keep the same volume the port came from the factory with and manipulate the areas and air speeds to get the most dynamic cylinder fill with a given combination. That’s the best way I can describe it.
S/ and SS/ racers have my respect. A minuscule amount of people love to work that damn hard to go that fast with so little!"
