Replacing 283 with a 327... issues?
Please Help! Im running into a brick wall here and need some help. For Starters I have a 1964 Chevy C-10 pickup with a 4 speed manual and a 283. I am in the process of replacing my 283 with a newly rebuilt 327 long block (from what I've researched everything swaps right over. In the process I have replaced every external component (fuel pump, starter, water pump ect...) the one thing that has me stumped though is what I should do about the engine oil breather canister located under the manifold. With this new engine (327) I will be replacing the intake manifold with a Edelbrock performer intake manifold (which no longer has the oil fill tube in it like the stock manifold) I have also purchased new valve covers with filler holes in them so this is my delima. Some forums I've read people say to remove the oil breather canister located under the manifold and tap a freeze plug into the hole that normally would lead to the draft tube. Apparently since I am replacing my solid valve covers with ones that have filler holes in them I can put a PCV valve on one side and a breather on the other and this will allow adequate ventilation for the motor. Can someone confirm this for me because it seems like people are talking in circles. Some say yes, others say no. Are their any advantages/ disadvantages to doing this? I basically want to make sure the engine is able to breathe enough, while at the same time not spit oil all over or blow seals. Any help is greatly appreciated.
