I installed the middle one in my truck last night 208 212. Low end seems better than 218 218 that I had in. Took me 4.5 hrs to install it up and running this time. Getting better all the time on cam swaps. Going back to the dyno and test it out soon. will let you guys know.

How much power did it put down with the old cam? How low in the rpms did you start the dyno pull at, 2500? I just wanted to know because I've been torn for some time between something like the one you just put in or something like the trucker cam 216/224. I'd like to know how much is gained/lost on the low end and the high end. Thanks for your help, please keep us posted.
