Pcv
I was wondering if it would be ok if I put my pcv line to the bottom of my aircleaner. Will this work just as good as going directly to the carb or intake manifold. The reason being is I don't have any vacuum ports available on the carb and I dont want to tap into the intake.

The PCV system was designed to work off of manifold vacuum..In other words below the throttle plates...Theres not enough vacuum above the plates (air cleaner) to operate the valve....What works best is a breather in one valve cover and a PCV in the other...At idle the PCV is closed and the breather which is piped directly to the air cleaner is pulling any blowby back into the engine..As speed increases the PCV opens and gets full circulation through the crankcase via the breather/air cleaner......If you don't want to tap into the intake..then a straight breather would be best...Depends I suppose on where you live (emission tests etc)...how new your engine is etc...
The cylinders have to be inline.!!!

Re: Pcv
From my understanding of how it works it won't get enough vacuum there to work properly.....Originally posted by BILLINABOX

But then maybe I don't understand it at all
I'm sure someone will let us both know

wondering if anyones ever built a 377 destroker? with a 400cu block and a 350 crank. wouldnt the lesser stroke distance create less torque or would the excessive rpm's make up for it. and would it be better off than just building a 383? kinda curious, so any info would be helpful.

Re: Pcv
you need to have vac. to your pcv valve for it to work, but if you dont have a vac. outlet then you can just put a breather in each valve cover.Originally posted by BILLINABOX

Everything got swapped over, had to build a bracket for the fuel pressure regulator, modify the throttle cable bracket, rebuild some fuel lines, pull the screen wiring and mount the new one. So far...
