I didn't know this before today, but apparently the m50 block is the same as the s52/s50.
Instead of doing a complete motor swap (I thought I would have to cause I thought m50 was a smaller block), I could just use a s52 crankshaft in my m50, bore it out a little and get some new pistons, etc. Would I need the whole s52 crankcase? It would be loads easier than an engine swap, and more importantly, cheaper.
Anyone have any thoughts on this?
