running bigger cams?

  1. #1
    this year im planning on spending a bit more money on my engine. i am running ph3s at the moment but not too clued up on the bigger cams yet. im wanting to have hi comp pistons and rods/bolts so i can run much bigger cams. one thing i wanted to know, when you are running bigger cams say ph4 or ph5 what else do you need head wise to run these type of cams? thankyou

    PH4s will cope with a hydraulic valve clearance but the PH5s will need solid lifters and need shimming out to set the valve clearance. Rebated pistons (high compression) will be needed for both.

    yer Ph4 I think is what toad running, i think he still has hydraulic followers,

    but need abit of head work to get the best flow, maybe get a c2 head

    thanks for the replys i think ph4 is what i would go for. i have had quite a lot of headwork done already which is good. i will have a look at toads progress thread

    thanks

    Prizes for not actually reading the OP sig go to



    On topic. ph5s need solid lifters etc.... ph4s can be run with hydros as said, id chuck some rods in aswell if going mega high. Either that or id run catcam 734s is staying hydro.
