is this a good cam for my 406???
I have a 406 with 10/1 compression, a ****ty set of stock 76cc heads that have been shaved 20 thousandths, they have 1.94 intake and 1.5 exhaust valves, and the cam I am using is a crane cam with 224/234 duration at .050 and 465/488 lift. The lsa is 114*. I am running long tube headers with true duals. any way, what I want to kow is will this be a good power cam for this motor or is it to small?? I want a good lopey idle, will this cam give me that?? the trans I am using is a th350 with a shift kit and a 2600 rpm stall. thanks

The Intake peaks at 109*, the exhaust at 119*.

As for the cam choice, what intake/carb are you running, what headers, how much gear, what heads? The idle won't be that lumpy in a 406 but don't base cam selection on idle sound. Base it as being the best match for the rest of your parts.

intake is a weiand X-celerater and carb is a 750 holley. I know I should be thinkin of performance instead of sound but I want both, lol. I am not tryin to build a race car, I just want it to perform real well on the street and sound mean as hell at the red light.

Is the compression a known number? Like did you run it through a calculator? Because, with a motor like a 400, they can take a bit more cam than what you would toss into a 350 and retain the same manners as a 350.
All other points the same, I would consider even jumping up to the Xe282 or similar. However, the heads, you say flow very...crappily (is that a word?). That will hurt things a bit as 400's like to breath. And naturally, the higher you rev, the more they like to breathe. As far as the heads, they sound like some mid 70's smogger, the 882 or similar. Not a very good performance head, to say the best.
What are the heads? What is the peak lift they can take? Rear gears? Desired RPM range? Lope is good, yes, however, lope and idle quality are inversly proportional, keep that in mind.

heads are 3998997 and shaved 20 thousandths with 1.94 intake and 1.5 exhaust. I plan on upgrading later just trying to recover from the engine cost and trans cost, lol I will replace them in a few months 3 or 4. what is the duration and lift of the cam you mentioned?

You won't be that impressed with those sucky heads...I have the same cam in my 406 and when it was carbed, the heads limited top end...actually it felt like the TPI bottleneck above 4,500 rpm...
I thought that cam idled pretty well though...a bit of a lope to get people know it wasn't a stock 305

The 114* LSA means that you will have a decent idle and it is still EFI friendly.
A lope is a lope...too much and it won't run...Believe me, it doesn't sound stock...but it depends on your tastes.

Yes...I saw that you are currently running a carb...but I used that cam because I wanted to be able to upgrade to EFI...which I did...
Nothing like planning for the future...

oh ok I see what you are saying, lol. Well I will give it a try since I already have it, and if I don't like it I can always change it when I get get my new heads in a few months.

The cam works in a 406...a good balance of torque and some upper power...meaning it will have good street manners from my experience.
Good luck...

yea I don't care much for a single plain intake on such a mild engine either, but it was all I had. I plan on changing it as well as my heads in a few months when I get some more money saved up. I would like to get a cam that works well with my setup and gives me that mean azz lopey idle

Ohhhhh i missed the single plane thing........get rid of it or bye bye torque unless you go with a small cam which in reality will defeat the purpose of having the single plane in the first place. It will prolly mph good but wont wanna get its *** off the line too great.
