I appreciate all my customers. I also appreciate the confidence they have in me...

This LS build was out of the norm as it is a Buggy/Chuggie for dune riding in MI. The engine needed power in a lower rpm band as this thing needs to a broad flat powerband for the applications. ATK's performance division uses me for special projects. Who is ATK. They are the largest supplier of core engines and rebuilt engines in North America. They could by a cam company if they want too.
And yes is a VERY small camshaft!

First cam offered me ..
580/564 w/ 1.6 rockers
237/241 .050
108 Sep sir.
I was told that cam would make 580 to 620 hp ? ? ? ? ? Yet you will be 500/500 ? I wonder how that works ...
I had a GMPP cam in a 350 .. Of course GM performance would be clueless on cam design, Obviously using a cam 234/242 .576/.595 112 LSA in a Crate 350 for the street makes them the fools. (ZZ465).. Apparently a GM847 is a 427 sbc cam not a 350 sbc cam. Can someone ring GM and let em know they made a huge mistake...
(PS) I ran that crate zz465 ..
Here is how to big a cam drives LMFAO (ZZ465)

Here is how a silly to big GM cam pulls LMFAO (ZZ465)

Additionally , I also have a cam a hundred thousands less then my max spring lift .. If 50 to 70 is max to prevent damage I guess I am living on the edge ..
Max Lift of my heads , .710" , with 1.6 rockers I lift .611" / .592"
It is all the double talk that infuriates me ... It seams to me the best cam to buy comes from a dart board , a blindfold and an open bar surrounded by hookers and nuns...If that is not available you can pick a cam grinder there has to be one somewhere . . .

You do have a very extreme wide ratio 4 speed auto trans with large rpm drops. It does seem you have picked good amount of airflow in the heads. With a low rpm goal curious as to what you yourself think you should run for a camshaft.
