Oil cooler lines. Can you fit a 12 AN?

[ng8264723]

I asked this in the main section. I then thought I should ask it here after someone said routing through the metal is the problem. I don't want to cut any holes larger. To me the Kirkham filter mount and the block mount have 1/2 inch holes in them. Therefore I thought the 10 AN was sufficient. I figure the restriction is the munts anyway. I my theory correct?

All of our big block FE oil lines are dash 12.

ng8264723 You have to remember that the fittings are smaller that the lines. The line my be 1/2" but the fittins could be 3/8" ID where the oil comes through. #10 IMO is bare min. size for any 427-428 motor in a street car that gets a little abuse. Get into these 482 and up monsters, #12 with hiflow fittings. Remember every fitting cuts flow of the oil down a little. I am going to #12 with next motor. What may be saving the motor in the car now is the 3 quart accusump that helps keep oil pressure and flow up on road courses. I do also run high oil pressures too. Rick L. Ps if your car is drilled for #10 lines, see not problem with putting #12 lines in. You may have to install the fittings after the lines are run. Measure 3 times and cut once. Give a 1/4" extra after getting the correct length. The lines don't stretch. Rick L. Ps will the block to the motor take #12 fittings or #10's? My need to get new block. Hope the main port in the block was opened up for more flow.

Rick,
Thanks for the info. I just wanted to make sure that I could fit 12's. David cleared that question up for me. I wasn't going to start cutting the alum to make 12's fit

Everything on mine is M22 (ORB) not 1/2 pipe... (AN-12 hoses though)
