If its a mostly street engine I would just use a good 10w30 oil and you should be fine But,make sure these measurements are correct and measured w/mic.Anything less I would go w/1X bearing.

Re: main bearing gap
would you say .0035 is to loose street/strip I do have a HV oil pump 8qt pan I know HV has nothing to do with pressure but how much would pressure drop going that big of gap by experience I also heard .0032 is the max I think but not to much literature on .0035 I just have to ask thanks for the reply's guys

Re: main bearing gap
Smaller clearance = thinner oil.
