Matman,

Just putting this information out there and my opinion.

I have a 1970 T/A with a 433CID engine with RAIV heads. The cam is a in the attachment. Engine uses RAIV exhaust manifolds with 2.45 outlet into 2.5 inch pipes. Total 31 degrees of timing all in by 3,500 RPM.

I would use this cam in a 406 with e-Heads. That's just me. Here is what the cam sounds like in a 433. Makes you wonder what the lope would be in a 406.

Boss made the video, but that is my car I am backing out.

Now, I do have a '78 with a 406 with 6X#4 heads. It has the cam in the second attachment. Here is what it sounds like. Has Doug's headers with 2.5 inch pipes. Total timing is 32 degrees all in by 3,000 RPM

The '70 T/a Has a HR with @ 050 numbers of 230/236 in a 433. LSA is 112.

The '78 T/A has a flat-Tappet with @.50 of 230/236 in a 406. LSA is 110.

Pick your poison.

You sir have a beautiful pair of hot rods. I was originally going after the xr276hr but butler advised against it with the 110 love sep. I had my eye on the one in your blue car and I see it is butlers grind with the 112 lobe sep I think I might give that one a try I’m just afraid the next step down won’t suit me and your 433 is what I’m after I do understand it will be rowdier in the 400 with less cubes but think it would be right up my ally your don’t happen to know what intake center it’s installed at do you.

I used that cam thats in his 433 in a customers 400 with allum d-port
head's sugested from KRE I was a little hesitant but that little 400 run
like a wicked 455. I was impressed with it.
it's in a 67 firebird and runs like a bat out of h-ll if ya know what I mean.
That's a great selection for a cam in a 400.
