Camshaft suggestions

all good points crackedback
Me I look at seat timing and duration at 200 where air is really flowing and power is made
which is why I would pick a 262 Lunati over a 268 comp
and the 256 jones will run better than either one of them problem is price and delivery
you are right about springs which is why the howard is a tough call
I use oil through the pushrods lifters and pushrods which really helps on the cups in the rockers
.050 duration is sorta useless except for degreeing the cam, there is so much variance in ramps
cheers
edit Jones is 120@200 but about the same as a 318 cam seat to seat.....
Jones is still relatively bigger at .275
to compare with Crane Jones is 264@004 and crane has a 268 special with 127@200 that looks about right if someone wants a little more duration than jones
but as you say you trade off on the bottom end
no free lunch
