lifter noise

[daddyoth]

my '00 limited intake manifold is leaking coolant and i think lifter is making noise i might go ahead and change the cam while i'm at it. my question is does the 5.7 have hydraulic flat tappet cam & lifter or does it have roller cam & lifter? would like to make sure before i placed an order.

thank you very much,

i believe all the vortec 350's are roller, they should have guides for the lifter in the valley to varify this.
