I am no cam guru, but, why NOT go with a cam that has been proven???
I just couldnt get myself to pay $400 for a new cam just to try it out cause I THINK it would perform better.... I myself would rather go with a proven cam than trying to guess what is better....

thats my .02

 

Could be in the larger port volume or in the shape of the port?

 

Correct!

 

Were you asking about the cam going in the 408???

 

IMO its because the heads are for a large bore and there may be a bit of valve shrouding. If he would have gotten 15rwhp out of his swap(he kept basically stock compression with the swap) dont you think his times would have shown it. Im not knocking doing the swap it just that at this point I havent seen anyone benefit from it in a truck app with a 3.78 bore, a tenth of an inch is a big difference. This is all my personal opinion and I could very well be wrong but I havent seen any info to contradict what I am saying, I would gladly eat crow if there is such info to be had out there.

 

Im personally thinking about getting Pat G to spec me out a cam just for ***** and grins to throw in later on down the road once I get bored, from the research I have done on tech the man knows his ****. My current cam is kind of a blah run of the mill cam at 224/224 .565 .565 112(or 114 dont remember off the top of my head).

 

The cam he speced for the Hauler's 408 is an interesting one for the goals that we set for his truck. This cam is built to rev, like really rev. He said power should peak around 6800 or so and should hold the power to about 7300, so ideally the shifts will be 7300 or so. These are the specs at .050":

XFI LOBES

242/242 .621/.612 110+4 installed on a 106 intake centerline.

I can't wait to hear the idle and feel it spin up to about 7000+!!! It should be nasty.

 

It is going to sound nasty about like this

237/242 .595 .595 112

Im guessing you have a degree wheel to install it on a 106...

 

big cams need lots of mods to extract the true power potential of said cam, like better intake, better heads, higher compression etc...

Some small to mid size cams, benefit better from more undercurve power with the LS motor as is, meaning stock compression and heads.

 

Well, 110 lsa and it has 4* advance in it, I think it should be 106 just installing it straight up. Wouldn't be a bad idea to check it though.
