Hi all, i'd like some feedback on how far one could deviate from the stock 112* LSA with the Rochester CCC system, provided everything's in proper function, which mine still is. I found some random posts from awhile back, but they didn't directly address my question.
Background: My L69 still lives, and lately i'm primarily interested in just keeping it running. Having developed an intake gasket leak, finding a Weiand 8000 intake to swap on, then realizing that I really need to replace the timing chain has prompted me to think about replacing the cam, lifters and springs while i'm in there, more as a maintenance measure than performance.
Having read about how the flat tappet cams are prone to wearing lobes down, I wouldn't be surprised if my stocker has done the same, or begun to. Not looking to do anything wild, I wouldn't mind going a small step or two up from the stock cam, but not far enough to necessitate doing head work.
Was considering this Lunati cam, mainly due to the closeout price of $31: http://www.lunatipower.com/Product.aspx?id=2935

I'd like other suggestions as well. Obviously an L31 engine would be best, but i'm in no hurry to replace the L69 unless it suddenly destructs.

 

I think that cam will work well for the application. Might take a little tweaking on the carb and the mixture solenoid as well as some base timing adjustment. Might like 2-4* more timing. I have a crane 272h10 cam in the 305 in my vette and it is a strong runner. Idle vacuum is pretty stable.
