cam lobes

I am hoping someone can explain a little about lobe separation.
If I have a cam with lets say 252@.050, 106-108 sep as apposed to a cam with 110-112 lobes what will be the difference in performance /driving?
What lobes would suit my engine/drive train set up?

Re: cam lobes

the lower the l/c the generally the more peaky the engine will be..
for example I had an E303 220 / 220 @50 cam in my 5 Ltr it idled qiute lumpy peaked at 2500 then run out around 5500 rpm, it had l/s of 110*..
My new cam for turbo.. Is 236 / 224 with 114* lob sep although it idles chopy it has longer power curve BUT doesn't peak the same or it wouldn't if it had same timing...This cam is a custom turbo with less timing on exhaust to help turbo spool and reversion at high boost..

Tell these guys your specs and they'll email back what cam specs are rquired....
