Slant six builders...Lets talk Cams

Halfafish, i'm very interested about that camshaft you ordered from OCG. I'm building a mild 225, 198 rods, 2.2 turbo pistons, Offy intake, Holley 390, mild porting of the head, compression in the 9's. In other words very similar to what you built. Like you, I'm building a driver but I want a bit more "go" but it still has to be streetable. Can you tell me how that cam worked out? It sounds like a good grind, given that Slants are more restricted on the intake rather than exhaust side.
I'm worried the 108 LSA might make for too rough an idle?
Any info on idle, power band, anything would be much appreciated!

Idle quality is not based on LSA. LSA and duration are intimately coupled. With a tight LSA and a long duration is what gives you poor idle with a lot of overlap. You can’t have long duration and low LSA and have low overlap. The OCG 2106 and the one discussed here along with Dutras grinds all have reasonably short durations. If you want low end torque you want low LSA and low overlap which by definition means shorter durations. I have the 2106 8.8:1, oversized valves and it pulls like a bulldozer up to 4000 then you can feel it drop off, as I designed it. Cam companies don’t really makes cams that are actually good for most builds, they make cams that have numbers that the average customer thinks will give them power. The cam I was working on with Dutra before his fire would NEVER be a commercial success because it had durations of 192 degrees with a 108 LCA, but the grocery getter on the street torque under 3000 RPM was exceptional in the model. We also modeled his failure cam grinds and the model I had said they would be dismal failures so we had confidence the model was accurate. My build feels like what the model predicted as well.
