    6.4 Cam In 5.7??

    Can it be done?? Been looking on the forums with no definite answer.... seems there might be a piston to valve clearance issue since the 6.4 392 pistond have valve reliefs in them?
    Anyone know?

    Why not go with an aftermarket cam?

    Yeah but I'm sure they designed that cam with VCT in mind. My guess is it would be a ton of low end but no top end, or vice versa, dog taking off then screaming up top
    Mod List in order of intstallation:
    window tint, magnaflow catback, airaid cai, srt shocks and springs, srt wheels, AAC interior LED Kit, 180 Tstat, predator 93 oct cai tune, srt sways, jba shorties, and sidewinder cam.

    You're factoring in a cam cost but by the time you throw in the required SRT springs, gaskets etc it's not worth throwing in a $60 cam with questionable gains IMO. Grab an aftermarket one used for like $250-300, the extra $ is well spent.

    I was told the same thing about running a 6.1 cam in my 5.7. I ran with or faster than the sidewinder cars I lined up against.

    I would check PTV clearance and also pick up an adjustable timing set just in case you need to dial the cam a few degrees.

    Does anyone have the specs for the 392 cam?

    I agree with concussion. You seem to be the pathway for the 2011 5.7 crowd anyhow. I say give it a shot. If it wont clear ptv the you already have the motor striped, just get an aftermarket vct cam.

    Ill still need to do springs if I do an aftermarket cam...
    plus the 392 cam is just as healthy if not more than most aftermarkets
