Vacuum?

[TF360]

Without me checking my vacuum at idle, what would you guys guess mine is with 9.1 360 with a comp cam 480 lift, 280 duration 230 @50 cam? I'm wondering about the PCV thing. Should I use a factory breather and PCV or would I need something different? Thanks

Get it to idle with initial timing of 17 - 18* and you can probably get away with the typical Chrysler PCV valve.

Yea, I was thinking a 70-71 340 used the same PCV and that engine was a little more radical. You would think the factory PCV would work?

I haven't tried one of these yet, but it sounds interesting.

You'll be fine.
I run a 230/110 with 14* idle-timing. It idles down to 550 dragging the clutch. Get your Transfer-Slots synced up and it will be fine. Autos can run more initial timing, until the T-Portsync goes away; but with a hi-stall you can get away with a lot.

14-15 and use the PVC
