318willrun....Just curious, do you put shorty-block hugger headers in the 0.4 penalty box? Also, why is the car weight 'No Driver'? Not criticizing, just asking. I think this 'Race' is awesome. Thanks!
First question is yes, all headers are minus .4, I didn't want to get into 1 5/8 vs 2" and all. However, no penalty for factory magnum or 340 exhaust manifolds because no way I was going to break it down by factory part numbers... LOL.
2nd question is just wanted to stick with a base factory number.
Keep in mind, it's just a generic penalty box. For example, I'm getting dinged for worked 318 heads because I home ported them. But, I could mill them .040 and install larger valves and my penalty wouldn't change. So yes, there will be advantages for some over others.
The first Pass by a racer made me feel good.... His index was 12.2 and he ran exactly that!!!!! So through the process of it all, the box nailed him to the tenth! I seriously doubt it will continue to work like that, but it should be fun. Are you joining????
