Tim Vibert installed a 302 into a F15 sunshine roof , and it had the auto tranny , maybe a C4 ? It was at Corowa in 1981 , the vehicle ended up in Tasmania where it had a sticky end, fishermen were using it on the beach and it was swamped by the tide .I have pics of it at Corowa .

As for your canister filter;
You may opt also for a spin oil filter adapter kit which can be placed
Anywhere and plumbed in.
On my 1-1/2t Chev bomb truck, the canister type is mounted on the firewall as these trucks had 235 in them originally.
There is an adapter avail for changing the water
Pump location as well on 216/235/261 engines

Hi All

The location of the oil filter on CMPs (Chevy) was something that was changed several times and was the subject of several service bulletins. The original location horizontal in the frame rail has got to get the prize for being one of the worst locations. There is a service bulletin concerning the change over to the larger military filter on the Pattern 13s and relocation to above the manifold at the rear of the engine.

I suspect that the location of the oil filter above the manifold on the CMPs and on commercial truck with 235 and 261 engines was to get and keep the oil hot so that any moisture would be gassed off as the oil passed through the air inside the crank case. This is and probably a cold weather issue. I believe there is also mention of draining water from the large military filters when vehicles are operated in severe conditions.

With conversion to 235 and 261 on my trucks went to spin on filters at Bob suggestion. On both trucks it is mounted down low and toward the rear of the engine where it can be changed easily but high enough up to avoid being hit by anything. As my trucks are primarily driven in warm weather getting the moisture out of the oil was not as high a priority. But it is an issue and the extra pipe and size of the pipe and the size of large spin on filters is increasing the oil in the system by 2 quarts. I also with the filter and pipes out of the confines of the engine box acts as a very effective oil cooler.

I have done temperature studies on the the temperature of the oil pan, block, and oil filter. What it shows is that with air temperature below about 70 F the oil temp returning to the engine doesn't get up to the engine water temp. In hot weather operation the oil cooler effect is probably a good thing. When I have the C60S with the 261 out on the road in cold weather I generally do run it with the radiator muff on.

One other point with the large remote oil coolers because of the size of the lines is that if one ever brakes off, comes off all the oil in the engine will be gone in seconds. Even with the 216 engine if one of the oil filter lines brakes it dumps the oil real quick. Only had this happen once and fortunately the engine was running on the test stand, when the brass Tee on the side of the engine broke off, suddenly there was a lot of oil hitting the wall of the shop, as I reached to hit the kill switch.

Phil:
Further to your comments re oil filter locations I remind all that many trucks had arctic/winter dilution kits in them. These involved a small gas reservoir at the top of the windshield which was filled up by an electyric pump controlled by a timer. I believe a similar kit was used on some armoured vehicles as well.
It would make sense that the filter waqs located close to a heat source (manifold) to help evaporate off the gasoline once the engine was started next morning. I wonder how long it would take to evaporate off the gas??

Hi Bob

Here is link to the Cold Weather Equipment Manual Suppliment including the oil dilution equipment.
