318 oil pan
Long ago and far away, in the mid 70's, I put a !!!!!!!! 360 !!!!!! into what used to be my 440-6 RoadRunner, and put the 340 that I HAD swapped into it into my old Toyota FJ40 RR. Obviously, this is long before Al Gore invented the internet, and in the back woods of N Idaho.
I actually took a scrap block, made a sort of trapezoid shaped cutting jig, and cut part of the rear of the 360 (truck) pan out, cut the same piece out of the (car) 340 pan, swapped the pieces, and gas welded them back in. PRESTO. A truck 340 pan and a car 360 pan!!
