    Hey Pman. I think the very first thing I would do, would be to lower the engine down in there, and put it on wooden blocks. Then put the gi-humungoid anoconda pipe-from-hell off the gpr in there.

    IF it fits, (especially wide) you are then needing to figure out some type of coupling. They are pretty different.

    You might be homefree after that.
