Quote: I have seen wide pans the fit regular blocks. the bolts were installed thru tubes welded into the pan
That sounds like a custom pan to me. Welding tubes, etc. The wide pan might be a good idea, I am just asking if we are comparing common parts to special parts. If a racers is upgrading to a new block and has all the other parts (oil pan), is he in for a surprise that it won't fit? And vice versa from a racer with a broke Indy Maxx block changing to a MP block. Full disclosure.
And IMO, if somebody is making a special block that is wider at the bottom, they should have real 4 bolt main caps, not just side bolted. Then the full advantage of the wider skirt would be used with all the special parts that are needed for it.
