Cams for 318's

340 cam can work and 9:1 is about the minimum
where it is a dog is on low compression motors
however you can do a lot better for mid range and the low lift limits top end
those 340 cams are also usually cheap
some like the 360 cam better
both have the problem of really long closing ramps and wide lca which cuts the dynamic compression
run some simulations
however- great jobs and thanks for the report
