A while since my last post, built an RB34 stroker motor and went for the JUN 11mm lift 288 degree cams spec. Now the cam is not big in my old Alfa 3.0 engine builds, in the 3.4 liter RB engine its massive ! Really battling to get good, consistent idle and some meaningful vacuum . I'm currently playing with cam LSA and LCA`s and with big timing figures(45deg) I can achieve a reasonable idle but its not consistent. Main input is MAP based. Any ideas from the big cam blokes here ?? Thanks...
