I was thinking of putting this on top of a ZZ4 shortblock along with the TBI, is this cam 'ECM friendly'?

 

any cam is ecm friendly if you are plannign to do some custom tuning anyway. it looks liek this cam woudl be pretty mild in a 350 really, woudln't be too bad to tune in at all.

that would be one hell of a cam to put in a TBI car!... are you sure you read that right NJspeeder, 235* intake on a TBI motor....man my car lopes good with 10* less duration

are you sure thats a roller cam? sounds flat tappetish
you need a roller cam in that engine....it comes with one doesnt it?

 

its hydraulic

 

Yeah it sure looks like a flat tappet cam. I think the ZZ4 is flat tappet also.

 

oops looking at the ZZ4, its a hydraulic roller

 

oh yeah it is too...
