How hard is it to split the case. I might install a +3 stroker if case is'nt difficult to split. I had a clamp fail and the carb. loosened up just enough to run ok but it leaned out and has lost some compression. Engine never felt like it was seizing up but it did loose a little power so I stopped to check things out. I went to refire engine and noticed most of my compression was gone. Then I found the failed clamp.
