Performance

This is something that everyone wants to improve on. I've read articles on here guy's asking how much compression can they run. It seems to me that building a engine going by pure stock drag racing rules a guy could build a strong running engine without a 10.0:1 compression ratio. Those guys have gotten some impressive results from a lower cr.

I'll take a stab at it:

You have to have a full understanding of ALL of the rules associated with classes like Pure Stock, Stock Appearing, NHRA Stock, Factory Appearing Stock Tire & others and not get them mixed up. I don't know all of the rules, but there are usually allowances that are not "pure" or actually "stock" anyway. Despite the best efforts of the rule makers, there are creative "grey areas" and rule "interpretations". Some people do achieve surprising performances. Detailed blueprinting helps a lot because "pure", OEM engines are usually pretty far off from printed specs. But the more rules/restrictions there are, the more expensive it is to achieve maximum performance out of a combo, which includes a lot of assorted fine tuning throughout the car. Not the best, simplest, cheapest or easiest way to reach an ET/MPH goal. But some people like and can afford the challenge.
