I'm currently running the Summit 6401 cam with (9.35.1)

282/292 adv duration
.465/.488 lift
114 LSA
(calls for min. 9.5:1 compression but seems to work very nice)



Comp recommended the 268H (21-223-4)

268/280 adv duration
.477/.480 lift
110 LSA


Why/is the Comp cam better for my setup for street driving. What are the differences in characteristics?

The reason why I'm asking is, I have to change the cam & lifters due to a bad lifter issue (long story ). Putting in a different cam may open up a can of worms with lifter preload and I don't want to go through ordering a new set of pushrods again. If I'm not going to notice a difference, it won't be worth the hassle. I might as well put another 6401 cam in...
