    Hi
    I'll be buying new cams soon but i can't decide between newman ph3 and ph4.
    First the car is my dayli driver so at first it should be raliable(i mean no chance of valves/pistons kissing). Untill now i use colombo and bariani cams 270/260 9.4/9.0 lift and the result was 140hp with head work and decat. Do you think the ph3 newmans will be improvement over my old ones ? And can i run the ph4 with standart pistons(i don't want to make pockets in them) ? And what you think about the combination of ph4 intake cam and ph 3 exaust cam ?
    Thanks!
