I just got my heads back from Lloyd and was wondering what you guys think about my cam selection for this set of heads. Right now I have a XE 224/230 with a .536”/.544” lift on a 112 lsa. My main question is how much power, if any, am I leaving on the table with this cam over a custom grind or larger cam? Here’s the flow numbers for the heads:

.200 134.5 100.4
.250 160.7 124.1
.300 188.9 134.6
.350 215.4 150.7
.400 233.9 160.8
.450 248.7 171.4
.500 256.5 177.6
.600 261.4 183.8
.650 262.4 185.6

I wanna keep the revs around 6100/6200 rpms which is one of the reasons I chose this cam. Stock valve sizes BTW.

 

Before you start looking for a bigger cam you should ask yourself a few question first.What is the car mainly used for,the bigger you go the more issues you will run into.

 

That cam is tiny because an XE grind of that duration is acctually a very small cam when compared to a slow ramp cam like a cc305, this XE would be considered much smaller then a cc305 but make the same power to 6k rpm where it will just plummet down, don't rev past 6k MAXXXXX!!! or YOU WILL slow down!
