Help me choose a killer cam for my 440

Help me choose a killer cam for my 440 - 11/17/11 10:23 PM

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.

you'll need more carb. Call Scott Brown. He has a nice solid grind that will work good it's 540-548 lift.

I'd run something in the 550 lift range & 250s @50 if your wanting somewhat killer. The .557 MP cam would be on the wilder side for a solid. I ran the last one in my 451 & really liked it, you really need headers if you want a killer type cam.

XE295HL is a good cam for an engine like yours

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

I agree.With the manifolds the MP .528 solid would be hard to beat.The .509 hyd would work well also.

none of the above. i don't like a lot of overlap on cast manifolds.

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.

use the lunati 30307 grind (240/250 @50 520/547lift) killer mid-range power....

Re: Help me choose a killer cam for my 440 - 11/18/11 05:51 PM

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

The cam you choose has a LSA of 110. I would have got something wider if you are planning on running exhaust manifolds.
