LOL...Too much cam for what?
If you have 8:1 compression, they are both too big.
If you have an automatic with a stock converter, they are both going to pull through idle.
If you have a 600 cfm carb they are both too big.
Do you get the point?
You need to list full engine specs. You can't guess at compression ratio.
Also list trans type, converter if it's an automatic, gear ratio.
I see you have listed a 1967 camaro with a 355. The cam is going in a 350, maybe it's a different engine and car, I don't know.

i'd personally go a little smaller on the cam, unless you are gonna up the comp., go lower on the gears, or get a shorter tire. that cam is gonna be sluggish at 9:1 and 3.6 gears on a 28" tire. you'll need to keep the rpms up around 3000 to drive it, and with a stick you'll be moving pretty fast in town to cruise.

I had a 292/501 back in the late 80's in a 70 chevelle with a 350. It worked great for what it was, pulled to 6500 with a single plan intake with no problem, and was about as high as you would want to go if you have power brakes. Anything bigger you would possibly need a vacumn canister to supply enough of it.

I had a 406 with a ST10, 3.73 gears.
Also a weiand x-cellerator intake, 750 vac sec.
It was in a '75 nova, it would pull hard at 3000 and up, seemed like 3rd never quit pulling. It went from 14 in the 1/4 to 13 flat in the 1/4 just by adding the 292 magnum.

You really need to cc the heads and pistons, and measure gasket thickness, piston to deck height, etc.
