First, i would like to say, this is NOT a oem vs acl bearing thread, i do not want to turn it into one, i dont want people to argue an make smart comments please. i just have a simple question for people who actually know what there talking about...

Okay, with that out of the way.. This is my first engine build, i am going to be taking my motor to the machine shop very soon for bore, hone and assembly.. i am going to be using brand new eagle rods and the crank will be micro polished. im soo confused on this whole bearing thing its not even funny.. i know there suppose to be measured an all that good stuff, but i see so many people running acl bearings without a problem.. i know acl's are not a one size fits all. i would like to have EVERYTHING i need for the machine shop ahead of time so i can get my motor back in a timely matter, and i dont get raped on prices buying through them.. my question is, do i have a good chance of the acl bearings fittings since i will be using brand new eagle rods, an having my crank micro polished.. if so or if not could you please explain?. any input on this i would greatly appreciate it.. i would like to use acl's for a few reasons, because of price, recommendations, and ive heard good things about them.. if anybody could help me clear this up i would appreciate it.. thank you

 

It's actually very simple.If the clearances with the ACL's installed fall within the clearance range they will work.I don't worry if the rod clearance is a few tenths big,but the mains need to be within spec.The main clearance grows because or the aluminum block.The only way you will know is to buy,install and check the ACL's.
