Hi
Did anyone used CCA-CL21-223-4 or similar camshaft on a 400cid about 9,5-10CR ratio motor before? Cilinder heads are stock, dual plane intake and headers. Your comments?
Thanks

In my early 1972 400 I used a 292-509 purpleshaft, and it was a real good runner. It had the std. bottom and std. 906 heads with a Holley street dominator and a early Thermoquad.
It was one of my best street engines ever.

AMC, For me it's more about knowing the head flow, the displacement and (primarily) where I want the intake valve to close. It's often better overall to put a slightly larger intake lobe in the motor and close it earlier, if you know how to 'get it right'it's a win-win, better overall power and no appreciable loss in low end torque. When correctly chosen, Crower's mopar hydraulics flat out work, better torque and power on both sides of the powerband than the lobe @ .050 might lead one to believe. As Dogdays said, I've suggested that cam on here for years, and other places both on 108 or 112 (depending on the app) and never heard nothing but great feedback on the choice. Nobody's run me off of here yet

Either one but the 108 would be torkier,...your car would benefit from a less restrictive intake up in Fort Collins the air is pretty thin.
how would a 108 be torqier than 112 108 has more overlap than the 112 thus not torkier.
Thanks for the suggestion, a new intake is part of the plan, figuring out which ones I can make work with the air grabber setup. I need to get another base and see how far I can drop it, possibly go with a performer, althought I would like an RPM, not sure if I can fit that. Maybe a dp4b edbelbrock if I can find one. Oh and Headers possibly too.

FWIW a holley street dominator is low profile. It does give up low end tq but it does as well up top as anything else per the great intake comparo tests.

Trust me here...I knows a little
Crower 271hdp 222/234@.050 .496/.486 cut it on 108 LDA and put it in +3 at 105 ICL This is an awesome 383-400 cam.....talk the talk and walk the walk
i'm running a performer rpm cam for now because it came with my top end kit. the engine is ready, waiting in line for dyno. i will let you know how good or how poor it performs.
the specs to compare to the Crower above:
Edelbrock 7194 238/246@.050 .480/.495 In/Ex LSA 110 C/L 105
my static comp ratio is 10.5:1
