Mopar Cam- how many more degrees @.006 to equal at .200?

Aj post 2

great job as usual

we'll get to the 340 cam a little later

one step at a t ime



I'll cover ramps ,008, 006, 004 later if anyone's interested



UDHarold said his chevy voodoo lunati 268 picked up 25 hp over the comp version

how much the Mopar version IDK but more mid torque for sure-

agree 100% does Hughes have a lobe catalo??g- I have to crossrefference to Howards or to Engles for earlier cams but some don;t match- maybe Bullet at one time?



Actually yr post 14 I think it's both

UDHarold said his opening and closing at the very ends of his ramps was changed between Comp and Lunati by adding another polydine (and more in the mid and going over the top)

so that makes sense in needing less spring pressure

we want neither bounce or float but want to do it with the least spring possible

yt post 15 agree hard to find the 200 data but IC is super easy- just hit “specifications”

I just wish they had more mopar lobes and they would update their profiles on their catalog grinds.



Rumble #16 Don't you love the Lunati on line catalog where all you get is a pictur and what engine but no clue as to the cam spec!!!



Hysteric post 19 tyring to keep it simple here

but going to a Mopar gives you much more than going to a 1.6 rocker

Now on our circle track build we are maxed out on the cam so 1.6 makes sene

also if you already have your cam installed and you think you can pick up some with a rocker change

you can but by the time you buy the rockers and a B3 kit and pushrods you could have got a better cam

valve speed does increase, but where?

but if you have your fulcurm too low it increases near the nose increasing chance of float

some run this way because you get more lift- some stock class guys delibertly if they can run a cheater spring. For most adjusting your rocker height (easy with chevy) for most lift is a fools game

roller rockers without adjusting th geometry gives this effect

and if too high like the Crane “quick lift” rockers you may need a bigger spring to control bounce

Most cams are ground assuming a linear rocker effect

sorry to get off your comments most applies to all rockers it's just that roller tips really throw off what the camgrinder unually intended



post 22 what rumble says



krazy post 23 That's why a quick look at intensity is important

but if you look at two Howard grind .842 series they get less intensity by being “agressive”

The Howard mopar lobe gets “intensity” from just being a larger lifter using standard profile
