Why the narrow LSA?

A 3000rpm stall is awfully low for that cam. I was tired of my 3000rpm Vig after a week, with less cam profile than you're running. 3400 or 3600 :imo

What type of fueling are you going with?

 

[sewlow]

WOW! That's a beast of a cam! 570 lift, in a small block. Piston/valve clearance is gonna be an issue. I've never gone over 1/2" lift on any of my sbc's, just for this reason. With that kinda lift, duration, & lobe overlap, it's a good thing you have that 3000 high stall. You're not gonna have much vacuum. I'd consider running a vacuum accumulater, for your brakes. With this, you can get at least a couple of good stops, even after it's turned off. I'm not sure if they were installed on diesel GMT400's, but I'd try there first.

Accumulators = Hydroboost systems came in everything from late 80s Astro vans to 1-ton trucks. They're a direct swap and are superior to vacuum systems in every way. Problem solved.

With that 110 LSA that thing is gonna be nasty. Can't wait for an idle clip. Is the truck TBI or Carb? Who's doing the tune if it's TBI?

 

[kevhill85]

Well funny thing is this cam smaller then what I have been running. The old cam wanted to run to high in the rpm range for me. I am try to bring the rpm range down to the 6 to 6.5k area..


The old Solid roller. 600lift

Eeeyikes! How things have changed since I built my last Hi-per. sbc, 20 yrs. ago! To my way of thinking, (old skool!) that is an absolutely monster cam. Wow!

This is the factory spec when I bought them. Now they are close to 205cc heads with all the work done to them. I am looking for the update flow chart
