Camshaft suggestions

Welcome Michael
max hp and drive ability tough goal at what rpm do you want max HP
have the heads/ guides been cut for viton stem seals and what lift
do you have springs
you are looking at 340 springs or better stock 360 springs will not do much
stock 360 you have very low compression so we have to close the intake early to get any torque
yes you can close it later but then you have no low end
perhaps AJ will point you to some of his analysis which is the first place to start
you need to post weight or body, gears and converter and reg or premium fuel and how do you want to drive daily drive back and forth to work or saturday night special

I just posted this in a 318 thread but
if we are thinking of a cam in the 256-260 range (would not ever use old comp 260h in 2018 no lift)

650 AVS carb is about right

I posted a whole list of short cams in the 340 cam thread which we can look at with different LCA's check it out
340 cam specs? see post 27 and 37 & 38
post 27 reads from shortest on the bottom the 256 comp is there and several others listed by duration but nothing from Bullet or Engle or Crower but you can get the idea
you are looking at short duration and high lift
Aj what DCR would he have with a Intake Close of 54-56 @.006? about right on the DCL?
could he use more DCL (earlier intake closed)depending on a fuel the fuel gotcha?
of course if this is a Saturday night special hot rod with low gears, loose converter
268 comp cam has all the problems of the 340 cam then it depends on how nasty and un-driveable you want it

we can get to the proper DCR either way
