hey fellas,
I was just wondering what size cams you 408 guys are going with? I am thinking about going bigger than my 242/248 .608/.612 112 lsa..., but didn't want to sacrifice too much driveability....
Any suggestions/recommendations....

I just made 425/445 on my new HPE 408, 11:1, 244/248 .635/.627 112 +4 cam, LT/ORY, and Stock 6.0 heads. The cam is a dog on the street at anything under 2200 rpm. I wouldn't really go any higher than what I have for a dd car, of course I still have the stock 3:42's so that doesn't help much with street driving.

Thanks for the input guys...
I put down 465/445 initially, but I had some issues w/ my motor and it was torn down and put together again. Spun a main bearing and found a broken valve spring. I added larger 1 7/8 headers, x-pipe and no cats..... I have a FAST Intake and LS2 throttle body on order. I really want to get to 530 to 540 rwhp on motor, just wondering if a larger cam would get me anywhere near that?

ihave 240/247 639/647 @114 dynoed yesterday 519/478.. drives good.. if you really wanted to get good power maybe you should get a similar cam to the one that vince has.. i think he got somewhere around 550/535 those are good #'s.. im also debating in changing it..

My 408 is being built right now at G-Force. I went with a 244 248 around 620ish 114. I have all the goodies in my sig going on it with a set of ET 245 heads. We plan on 530 rwhp and 750rwhp on a 200 shot. I wanted good DD attitude. My car is full weight, A/C, and all. Anything over 500 is good for a solid street car! Driveablity is very important to me. My wife drives it everyonce in-awhile!!
