Slant six to small block 340-360 engine won't fit.

That is a truck pan and mounts. You need to pull the engine and go shopping. Also the 360 pans are on their own . You need a 360 car pan.

the mount looks to be a correct conversion mount. oil pan is deinatley a truck pan though.

depending on the manifolds or headers you use you may or many not need the 90* oil filter adapter.

these are transdapt s6 tp 360 mounts. the pnes you have look correct.
