Some of the issue that have us where we are is allowing unlimited spring pressure. The trick lifters with ceramic pucks require more spring pressure. Otherwise if they are not controlled the puck shatters and tears up the engine requiring a rebuild. With unlimited spring pressure a more aggressive cam lobe can be used and the lifter will stay in contact. Tool steel trick lifters for my combo 8 years ago cost around $700. Now we are allowed roller rockers too, so every rule change that allows something, opens a can of worms. Being able to run under the index costs money. How far under dictates if it's a soft combo or not. Most of us test a lot in order to refine what we have. I test more than I race, as my combo is not underrated like some of the other combos available.

Sorry Brent if I hyjacked your thread! Keep plugging away at it. If it was easy there would not be any challenge to making your car run well. Challenge in Stock usually means $$$
