I will finally have a dependable super strong 355 engine.....

Re: My new 355 4 bolt main build
well alot of people said that its not needed because it puts a lot of excess pressure on the distributor/cam gear and will wear that prematurely and something about it foaming and causing the oil pan to become dry or something like that........ so i just went with a regular oil pump.....
