Hey guys. I have some questions about oil coolers.

How do I plum to the engine? I'm using a sandwich adapter for oil pressure and temp. There are two unused ports in that adapter. Can I use those for the oil cooler? One of those ports would be for the supply, but where does the return go? It's an LT1 with a Moroso pan.

My other question is are there any problems with mounting the cooler above the engine in the hood scoop? I'm planning on securin the lines to the bottom of the hood and run them down the drivers side hinge then to the engine. I can't imagine there would be any problems with the location, but I thought I'd ask in case you guys know something I don't.

I'm not going to run a thermostat for the oil. I'm just going to tape the back side of the cooler for street use.

Actually I think this is the thread pitch I need.




For 13/16-16 inch thread and 2-5/8 inch gasket size spin-on oil filter.

The adapter and thread sizes you mentioned are for a 1st gen SBC. My '93 LT1 used a metric AC Delco PF52 oil filter that had a thread size of M18 x 1.5 and used a different gasket size (slightly larger?).

I think that you can install the old 1st gen SBC spin-on oil filter adapter in the LT1 block to accept the the sandwich adapter you selected from Summit Racing. Unfortunately, unless you find one used, the new ones cost $$.

If this seems like too much bother, I'm sure someone sells the correct hardware for an LT1 sandwich adapter.
