I am swapping a Chevy Inline 261 into my '50 Coupe. The 261 has a full pressure oiling system that has two 1/2" ID oil lines that exit the block on the driver's side just below the dual headers and exhaust pipes. These lines run to a remote oil filter on the firewall. The one line will exit and run within three inches of the nearest exhaust pipe. The other one exits the block and runs withing an inch and a half to two inches from the header flange. What type of hose do you recommend I run for these oil lines to withstand the elevated temps near the exhaust. Can I get away with one of those thermal sleeves that would wrap the line at the spot where it is close to the exhaust? Is a braided line my only answer? Thanks.
Take a look at Deve's Antique Chevy Truck site. He has a trick setup using copper lines I may change over to his set up. I'm running hoses and filter from Summit. The filter is mount on the bell housing. Im not able to add photos to this site. I know its me, not the site.
A source maybe marine applications. My Mercruiser 454 had remote oil & fuel filters/coolers rubber lines that are still holding up 44 yrs later. Kiekafer puts these Mercrusiers together as good as can be. You need something rated handle 300F
Be careful with the braided line. Most are not ment for thermal protection. The braid is usually for abrasion. They'll look good on the outside but melt on the inside. I'd use a thermal sleave if it were me.
Should be standard pipe threds,can you just use a few ******s& elbows to get away from th heat? Hope this helps Russ
Hard line or aircraft style (Aeroquip, etc) hose with braided exterior will work fine. You've got decent air gaps between hose/line and headers which helps keep the heat transfer down. Thermal wrap on the lines in the header area can't hurt. Make sure you have a flexible connection(s) between the cooler and the engine. Been doing race cars this way for decades without problems. vic
