Picture of 340/360 head porting....Mistakes?
lost about 5 cfm through the entire curve
And that's a damn hard 5 CFM to get back.
Again, there's more to horsepower than CFM. Even though skrews only lost 5 CFM, that chamber will be down on power on the dyno, and on the track, the car will be lazy in th gear change. The more gears, the worse it will show up.
That is pretty much what a W-5 chamber looks like. I have run as steeps 55* seats on that chamber and found power.
Cudafever, I run 50* seats on the street. In fact, my next W-2's are going to have them, with a relatively small valve and hopefully a bowl of about 92%.They don't beat in any quicker than anything else.
