MP DISTRIBUTOR TIMING CURVE 340
I have never had any success with plumbing the PCV to the Secondary side. and
that PCV hose has to be rated for vacuum, else it will get sucked flat when the vacuum rises. Fuel-line will NOT cut it. Transmission line maybe. But your jobber should have a thick-walled hose just for that.
Plumbing to the back, under the fully closed secondaries, that incoming PCV air is dry, as in, there is no fuel in it. Thus whatever cylinders get that air, will run a hair lean. You can sorta fix the front with the mixture screws, at idle, but as soon as you tip in the throttles, the Messed up AFR makes trouble.
I tried this once, and that's how I found out.
Many years later, having forgotten all about it, I tried it again, Bam!, then I remembered.
2500 stall, 3.23 gears, auto transmission. This is going in a '71 Demon cruiser. I am hoping the engine will be punchy, and have the balls when I pull out to pass.
With 3.23s and 27" tires 60 mph = about 3850 at WOT. At a cylinder pressure of 185psi, your demon would positively scream past any slowpoke in your sights.
However, if your pressure is closer to 150, well, let's just say, the balls are not gonna have reached puberty yet, lol.
