On most case sets, U & UL, that I've seen the rear cylinder webbing has been removed, either machine cut or snapped out, granted this allows more oiling to the hotter rear, but isn't this a trade off for case strength?
in building a stroker wouldn't one want the rear web in place? I notice that a '38 UH case set has both front and rear webs intact.
is this true with all UH & ULH cases?
also, just what is this talk about these cases being weak, Is this a thickness or poreosity of the alloy problem?
a few builders will coat the inside of these cases with a glyptal or rustoleum primer.
now this accomplishes three things; keeps embedded debris on the casting, keeps oil from oozing thru any pores, and the oil slides off easier a little free horsepower.
