Performance timing

I have a push on chrome breather on the passenger side valve cover and a pcv valve on the drivers side. Do i need to get rid of the pcv and put on another push on breather? Also my 727 has a stock torque converter . My truck has power brakes. Do you think ill have to drill those holes on thebutter flies on the 600 eddie i have on the engine? If i remember after i put 500 miles on the new 318 i did a compression test with it warmed up and plugs out coil wire disconnected and 4 barrel wide open and i think it was 130 psi per cylinder . I let it crank 4-6 times each cylinder

Leave the PCV system on it.

I'm not sure why you'd need to drill the butterflies if you can get the engine to idle at the correct RPM without the idle screw being all the way in.

You need to read some more about the difference between intitial and total timing so you understand it. Like mentioned above, some of the MP distributors have a pretty quick curve in them, meaning you'll get the total timing in too soon. I'm all for a relatively quick curve, but you have to manage advance so you don't get rattle on tip in. And if you can, you need to run the vacuum advance. That distributor SHOULD have an adjustable vacuum can on it so you can at least control how much vacuum advance you have.

You may want to find a local guy to put your distributor machine so you can get an accurate look at what the curve really looks like.
