318 driver - cam change or not?

Aaron
thanks for posting
The 204-214 is specced at .004 whearas the comp is at .006
so the 204-214 grind looks longer
there is some difference in the lca
they are both "universal" grinds"
both give up much area under the lift curve

On a thumper style cam
here the idea is to squeeze the lca to get the intake closed resonably early with a large intake lobe
however I do not know of one of these with an intake that closes at low 50 degrees at .006
most are larger- if you find one let us know
with a 256 @.006 lobe you really do not have to squeeze the lca that much to work
and as I posted above a modern 256 lobe can have the duration at .200 greater than a 220 Magnum lobe
.200 is what you want to watch for power - much better than .050

Garrett is that melling for a AMC-6?
anyway problem with advancing the 204-214 cam is that it opens the already early exhaust way early
AS UDHarlod posted 12 years ago the wide lca of the HP cam and the 204-214 was used to convert performance cams to smog cams - the wide lca - low overlap- reduces oxides of nitrogen
I think I posted the seat timing above or maybe in another tread
did you read the 318 cam stickie at the top of the forum
