question on cam vs springs
I just picked up a set of fresh 882 heads with a stock replacement valve springs from local shop. My question is... can I get away with a cam thats in the 440 lift range without coil bind. I believe the stock replacement cam is somthing in the .396/.400 lift. I don't think an extra .040 is going to hurt???
Ill check for coil bind but just looking for thoughts... The heads are going on a fresh flattop 355 and will end up in my 86. The 180,000 mile 305 is dead tired.

Re: question on cam vs springs
i had some 882's on my 355 1.94, 1.50 valves and 76 cc's well i ran a 268 cam from comp and had no problem i'm thinkin it was like .454 lift it worked fine however i wouldn't recommend going any bigger than that but it was a great camshaft

Re: question on cam vs springs
Chevy ran as much as .450/.460 lift on standard 3911068 valve springs, the same springs found on 2-bbl V-8's.

Re: question on cam vs springs
You could actually run alot bigger cam with the stock springs. I have those heads on my roller 350 with a hot LT-4 cam. That pushes .525 lift with no probs. I went ahead and put in screw in studs, though, just to make sure I didn't knock one loose and may use stud girdles later to even out the tension a little.
