80 degrees of overlap, 30 degrees at .050" lift. That thing will thump pretty good and make good power from 4000rpm up. The lift is rather low but I don't know your valvetrain setup or your PtV clearance. What is the stall on your converter? 3500+ if you are primarily racing I hope.






I don't really like any cam company's off the shelf cams. They can all grind the same stuff. Comp has far more exclusive lobes available to them. The only place that can rival comp on the newer stuff I work with is Cammotion.




The LSA is 108 which is pretty tight. It will bring the power down to a usable range. 300/300 duration is pretty high for a mild small block. The lift is weaksauce if he is primarily racing it which I'm assuming he is because he isn't running roller lifters.

It's not the lift I was talking about. The duration is gonna be what makes this thing idle like shit, not "fair"

Just watched the guys pit acrossed from us change a motor and piling system, that's a $85k whoops and they are acting like it's not a big deal..... The got 2 more motors not including the one they just dropped in.


I guess what they say is true....


If you're not ready to watch cash burn on the ground, you're not ready to race.

The duration and lsa determine overlap which directly sets idle quality. 108 is just the lsa which by itself means nothing.

Fmx yea 3500 stall and going to a 1.6 rocker so i should gain a little lift the cheating way and yes its gana be racing mostly will still strret drive just to fuck around
