Cam help.
Cam help. looking to swap out the factory cam and dont know what to look for or what. currently stock for the most part but looking to run 1.8 YT RR with new era performance's low lift cam can some one tell me if i should be ok..really confused about all this lift and ramp rate stuff?i got a LS4 and dont know what the specs are for the cam since they seem to be very mysterious.lol but either way believe its still a peanut cam .nothing major just with some advantages.also believe the lifters are good for .590 lift can some one tell me where i would be at if i ran the 1.8? thanks for all the help and please excuse my noob question..lol
1.7 vs 1.8 All of the listed cam lift values are based on the stock 1.7 rocker ratio.
Just take .590 and divide it by 1.7 = .347 is the acutal lift of the cam lobe.
Now take that times 1.8 = .624 That's your total lift with 1.8 rockers.
Are there provisions on the side so you can slide the cam out, or will you have to drop the cradle and lower the engine?

I'm a little confused if I were to divide .590 by 1.8 I get 3.27 and can u explain the numbers cause if u do it for the 1.7 shouldn't u do it for 1.8 seperatly instead of adding them up? And yea I gotta drop the cradle and lower the engine . Drive belt is on the passenger side
