Decided to ditch my cc305 cam for a LE 216/224, .568/.565 112 LSA cam since im looking for maximum torq/hp below 5500rpm.

Will this amount of lift work with my gm 1.6 roller rockers? I read that these rockers are only good to .575 lift.

Im assuming my pac 1218 springs will be adequate?

Honestly best person to ask would be Lloyd himself, he knows all the specs on his cams and has probably seen the results of most every cam he's spec'd or Atleast one very similar to it.

Generally the cam lift specs are based on a 1:5 ratio rocker...with the 1:6 it would appear the LE cam exceeds the max lift of the GM RR

Certainly confirm with Lloyd the cam specs are for 1:5 lift and then do the math for 1:6...which would be above the .575 max lift of the GM RR

He spec'd it for 1.6 rockers. It will be cutting the lift max close?

Iirc Lloyd specs all his lift numbers with 1.6 rockers

well if true than the lift is "just" under what OP says max lift is for the GM 1:6 RR. but at .007 under max lift I think that is to tight

Again, ask Lloyd if those RR should be used
