@.006 lift=273/277 111 LSA 109 ICL

Make sure your values @ .006 are correct on the calculator.

My 223/227 .636/.639 110LSA +0 cam was designed for my combination of high flow, high compression heads. It is not ideal for stock heads nor somebody averse to running dual springs.

Even XE-R lobes need dual springs...they just don't require the shimmed Platiumum springs like LSK lobes. But don't be fooled...when setup properly, the LSK lobes will not wear out springs any faster than XE-R lobes...in fact, they may last longer (because of softer ramp off the seat).

For stock heads, you definitely want a 110LSA and you certainly want to keep your intake valve closing point around 40 degrees ABDC for higher DCR. Keeping all that in mind, a 228/232 .588/.592 110LSA +4 cam would work great with stock heads.

Yeah, I had my figures set at .050" cam timing and the TQ #'s are always higher than normal.

You have to take the .050 specs and then lookup the .006 specs for that type of lobe on the same cam and enter them into the DCR calculator. To get the right DCR on the calculator you NEED to have the correct .006 specs in there, if they are wrong the DCR will be wrong too.

You can also look at 230/224, .590/.581 111+4 (XE-R) will have excellent midrange trq and upper pull.
Or another 224/224, .581/.581 110+4 (XE-R), mundo trq and one of the flatest trq you ever seen (if done corectly will produce equal HP/TRQ values)
