Whats your thoughts on this swap?
Hey Summit- Any more hints on these forthcoming lower powerband cams? Like, will they give Cam Motion's truck cams a run for the money?
Speaking of which, one thing I think should happen to C.M. truck cams is to narrow their LSA a few degrees, after I saw what that does to the BTR Truck Torque cam with its 111LSA on a 202/202 profile. Torque added to below 2500, more than I've seen with any other truck cam.

Yeah, I get the valve events reference, but in conversation cam specs are easier to deal with.
Other factors for me are- being stealthy (stock or near stock idle- gotta keep the smog ***** at bay), low IVC to build low end torque, and hopefully able to retain stock tune because I hear the newest inspections watch bitsum numbers to see if the tune is messed with. That last might be just a monster-under-the-bed groundless fear (Calvin & Hobbs ref.).
Having spewed all that.... another few weeks?
LOL!! Awwww MAN! Is that ALL you got??

Fellow catalog junkies concur, but I think if summit busts out some new LS grinds they'll probably start a new thread?
I can vouch for the quality of their stuff though as I have an early version 8714 that I ran for over a year sportsman drag racing. That engine hydrolocked in my driveway after the season and a rod came in contact with one of the cam lobes. I cleaned the lobe up the best I could with steel wool, Cross my fingers and threw the cam in my cobbled together Auto X car. Put another 20,000 mi on the cam and more than 10 auto-X events bouncing the engine off the rev limiter. I took the cam out a month or two ago to replace it with something a little tamer with less duration and the lobe that I had to scrape rod metal off of previously and smooth with steel wool had "machined" itself smooth as glass along the lifter path and the lifter wheel was still perfect.

And yeah, I kinda hope the new cams warrant a new thread, too. Hoping it's soon!
As the great Happy Gilmore once said...Somebody's closer..
Kidding aside we're getting there but not quite there yet. We're waiting for these to come into stock and be available to the public before we announce specifics. We'll be sure to let the community know in a new thread when that time comes

We talking another week or two?
Soon G..soon
. When the time comes we'll be sure to put up a new thread to let the community know all about the new cams!

In the near future some factory electric fans are planned, which should kick things up some.
I wouldn't mind getting around 20-22 mpg highway. It's a goal, though not sure how realistic.
Thanks for asking!
