Wondering how much hp difference in hp/et if the valve spring rule
was not changed? With the improvements in ring packs,head work,carbs,headers,converters,transmissions,suspen sion.tires, do you really think it would be that much of a hp/ et difference with current technology? I can see the roller rocker change for cost savings/accuracy but do you think that with todays cam lobe technology stocker engines today couldnt be close in hp without the roller spring pressures needed to control the valves.In other words was it in the cam/valve springs or in every thing else as a complete package. I'm thinking out loud, looking for some insight. Joe |

In a few years of doing this,having built 4 or 5 stockers from the tires up,I've come to the conclusion that no particular one thing does it all. The engine is only half the battle of building a competitive stocker. The rear end gearing, tire size and compound, trans low gear ratio, converter flash points and higher lock up,header size and length, carb modifications and jetting, cylinder heads, pistons, ring selection, the possibilities would fill a large book on even a simple car. In short, all the ducks need to be in a row for it to work. As time goes on, some ducks get substituted for even better ducks. Some ducks get changed, then to find out that the original duck was better. One cam might really make it scream on the dyno,only to slow the car down on the track. The drag strip is the ultimate dyno.It is the one constant we all need to use that matters.
