roller cams are "fatter" at the approach to the tip of the cam lobe
fatter ot "rounder
the lobe of a slider cam is pointy -er if you will
hard to explain without pics side by side
as for the 314 cam
do you have lots of really steep long hills to blast up?
'cause that cam LOVES a workload
and I've used one in every motor but my first
cam wore out in the second motor and the 314 cam & parts was a fraction of the cost of the original parts at the same dodge dealer so I went with it
L body 2.2 - can't say I noted much difference on flat areas but holey BLEEP does it ever pick up on a nasty hill
I live on the very edge of suburbian toronto .. and the world's largest "park" right across the street
lets just call it a nurburgring simulator and be done with elaboration. i said to be VERY naughty...
anyways the hill in front of my house was "the hill"
like running up the side of a 15-20 story tall building - with am S bend halfway up
you cannot cone out of the S at more than 25 mph
top of the hill turns to the left yo you have to mind going straight over will land you in the ditch
so , stock cam , turbo 2.2 would go over the top at 55 flat out holding nothing back
same hill , same car with 314 cam
car goes over the top at 75 mph..and I'm back peddling going over the top so I don't run off the road
it would have done 80 for sure and might even be able to go over the top at 85 - IF the road allowed it
and the hill is steep enough you can't back down it safely as your mass will overpower your brakes reversing down and backwards U turns at the halfway point MIGHT roll your car over
it may not be an engine dyno is some shop somewhere but you really can't compare to the real world conditions till you get it out there
sorry not my vid .. not my music
and figure to start , a wide open blast down the first hill
wide wide open...
