Oil cooler - line size??

[jms]

I'm thinking about installing a small engine oil cooler using -6AN line (I actually have some Aeroquip hose and some ends left over from other projects). Here's my question: is the -6 size enough? My motor is a carbed 350 w/ Vortec heads, stock cam, and rarely sees anything over 4000 rpm. I just don't want to starve the motor for oil. As always, any info is greatly appreciated, thanks, michael

No.

You need -8 at a minimum and -10 would be prefered.

factory engine oil cooler lines are 1/2"ID hose with aluminum tubing that is only 1/2"OD
sounds kinda -6ish to me

-6 = 3/8

-6 AN = 6/16" = 3/8"

If 1/2" is stock I'd go no smaller than that, which would be -8.

Thanks everyone for the information /forums/images/graemlins/thumb.gif ; I had initially scoped out a compact aftermarket cooler that has -6 fittings, but got suspicious when I saw that the Moroso oil filter adapter I planned on using has 1/2"NPT ports. Would have been too easy to just use the plumbing parts I already have, back to the drawing board....
Thanks, michael

Michael....when i finally added the factory cooler to the 79 i made mine out of number 8 an....and bought some adapters from a hydraulic shop to mate it to the gm cooler...cheaper than buying gm lines if you should choose to go that route...
