@low72 It's for crankcase ventilation, to allow pressure to be emitted out of the engine. Typically one valve cover would have a oil filler in the grommet and on the other valve cover a PCV valve hooked to a hose redirecting the gases back to the air intake (re-breather). That's typically the stock smog setup. High power motors have higher crankcase ventilation requirements and many who build moderate motors don't design them worrying about smog so they just put filters in the grommets.
I just built a 396 .708 lift 272 278 duration @ .050 , 049 oval port heads ported and am putting tunnel ram on it ,dynoed with single carb team g intake ,made almost 540 horse pulled to 7500 rpm no problem, yours sound awesome !
its not the high lift dumasses its the duration and how long it holds what lift it has that makes it sound gud. i had a cam that made .520 .520 and 246 246 @.050 and it sounded like a beast but didnt even max my heads out so yea
I also have a 396, mine is in a flat bottom v-drive boat. i am unaware of the internals on the motor because i recently got the boat and havnt had time to tear it down. i believe the compression to be at 12 to1 or higher because it is a cam2 motor. what should i be expecting horsepower wise?
could you give me some pointers on this engine i have a chevy 396 bored 60 over flat top pistons i think a 590 comp cam all the bottom end is stock and so are the heads. what could i do
this engine was not dynoed the engine builder could only estimate he told us it was definitely capable of running a 7 flat in the 1/8 mile in a 69 camaro

Hate to see the valve train after the low rpm after start up. Should be around 2000 rpm for at least 20 minutes. Thats my opinion.
