Stroker Vacuum?

[spoolinawd91]

I think some odd is going on with my 2.4, I have FP2 cams and I see about 14-15 vac at idle (1000rpm) and only about 19 when I let off in the upper rpms. My question is does this seem normal? And what kind vacuum readings are people seeing with your strokers with cams at idle and when you let off in the upper rpm's? Reason I ask is my car runs rather rich and also from what I've been reading (did a search) the vac I'm pulling is what most 2.0L's do with these cams.

I have an 8.8:1 2.3 stroker with Comp 200's (equivalent to the FP2's) and I see 15-16 in./hg. at 700 RPM and 25 in./hg. on deceleration. I agree that your vacuum may be a little low for your setup. I would spray all of the vacuum lines with carb and choke cleaner and listen for changes while at idle. If idle jumps, drops or fluctuates, you likely have a vacuum leak.

Good luck and enjoy that monster,
