Here is the rundown of my combo:
-440 STOCK STROKE
-forged pistons
-10,5:1 compression
-440 source stealth heads, port matched bowl blended.
-Performer RPM intake port matched
-440 source adjustable rockers 1,6 ratio
-I have a 750 DP holley carb, although I think it might be too small, or is it OK?
-I plan on using 70.71 HP exhaust manifolds
-full 2,5" exhaust
4,10 gears
4 speed transmission
this is going in a 71 cuda in full street trim.
I was thinking it might be the ticket to use a solid flat tappet cam in here? No, I dont want to spend more on a roller.

Less is more. .528 if you want something off the shelf.

242@ .050 on a 110lca. Lift will be about .560 gross and only about .014 lash.

M.P. 528 solid.
With cast iron stock exhaust manifolds, it is said to work very well.
Iīve heard that so many times. So thatīs the cam I would pick.

I had already bought this cam for this engine: http://www.summitracing.com/parts/CCA-CL21-225-4/But I started this thread because I thought it was a bit small and I was leaving power on the table. This is a street car but that will see some strip action. It is a 71 cuda with a 4 speed and 4,10 gears like I said. How much power do you think Id be making with the above cam, and how much more do you think I could gain by going to a solid like the MP .528" or the Scott Brown?

remeber the 528 is going to be about 500 once you adjust for lash. I ran both in a 440-6 (528 and the 548) the 548 felt much stronger.
The one you have now seems like a good cam. Just run it
