i am trying to see what cam the guys that have a 408 are running. i am bulding mine to be n/a and i want get the biggest i can and it to be streetable with a decent idle because there are times i am in alot of stop and go traffic and i also take long road trips when needed. i have been looking at the comp cams XER273HR but i am not real good about cams picking cams out.

Mine is drivable but if I had to drive it everyday in stop and go traffic I would probably go with something smaller. With the torque of the 408 watch out for cams with too much bottom end.

The 4l65e with the 5 pinion plantes doesnt like to be spun real high.What RPM do you plan to shift at?Forum member C5C6 ran 12s NA in his xcab AWD 408 with a pretty tame cam.Im going to guess something like 226/570 .A 300 shot put him in the 10s

a 226 is pretty dang mild considering a lot of people run stuff similar in size to that in a 5.3 but depends on how sreetable you want it you will lose potential going with something that small IMO i would go like the 232/232 not as streetable but still good enough

Matt, my cam is very streetable in the 408. It idles well at 800 and makes very nice power.

Lingenfelter GT1 all the way. If i can drive mine every day with that cam in a 5.3, you can drive it in a 408 easily.
