Default Mast Motorsports LS7 cam kit
I've had a Mast cam before and liked the power and idle it provided me. They seem to be a top notch company and I'm looking to get the LS7 cam kit.

Since they are sponsors on this board, I would like to ask a direct question here.

The LS7 cam states a lift of 0.639 lift with 1.7 rockers. The max lift on their springs is 0.650". When converting the 0.639 lift to the 1.8 rockers, I'm getting 0.676" of lift.

What goes here? Should I just buy the cam and a 0.675" spring from another company?

I am pretty sure MAST has a .700 lift spring.

Sorry for the confusion. The lift for our LS7 Cam is .639" .655.2" with a 1.8 Rocker not 1.7. However, that kit does come with our Dual Nitrided springs good to .700" lift.
