Long valves on W2's with .600 lift?
Jim and I are more than spectators and WE dont know what cam is being used!
I guess that’s why I got confuse and wondered about what cam your going with. Thinking you had one picked out and possibly on hand. I have not fully kept up with the thread, obviously... and thinking I missed the cam choice... Ha ha ha
To even think about a spring, I’d need to know everything about the cam for starters and the available spring height available just to name two factors.
But you got this. You don’t need my amateur *** blowing stinky wind in the B flat note. I’m sure you’ll get that right.
I'm trying to convince Mike Jones to grind one with more than .570 lift.
What PRH said I guess. There is only so much lift to get on a lobe per the amount of duration and have something last. I get cams, though I’m far from an authority of any sort.
In many applications I suggest to many on getting the most you can get to take advantage of the heads flow but it is not the end all. As we know some people go pretty freakin quick with modest lift cams. Going to a 1.6 rocker solves a lot of that lift issue of course.
If anything, get what you can get with the cam and rocker combo and if it falls short, I would not worry about it. The duration is the bigger consideration since it is the rpm band it will operate in and work in concert with the convert trans rear and tires to be sorted out when you cross the finish line on a drag car and in the roundy, the straights to the turns and how it comes off or out of the turns. Lift plays in second.
Yes, we know it has a direct impact on HP, which should be sought after but not at the detrimental expense of torque while racing around in circles.
FWIW, my W2’s (& W5’s) are bare (& fully done) in there boxes waiting for me to retire shortly. Until then, it’ll be the Edelbrock heads.
For now, I watch, read and learn.
