Hi to all; newly registered to site, following for awhile;
I am thinking about rebuilding two 454 bare blocks, one to be counter rotating. (Then, when necessary swapping for the original iron in my boat.)
My research has shown that the two engines are identical except for timing drive, seals, camshaft and of course firing order. What puzzles me is that one site lists a different crusader BLOCK part number. Since the cranks are the same, is their some oiling issue from rotating the crankshaft in the opposite direction. Does the crankshaft have to be drilled differently in the counter rotating engine? Since I am not tearing down the original beasts, I can't know this in advance of the rebuilds.
Thanks to all for all the great information on this site, and any help appreciated.
Cheers,
Larry
P.S. anyone with bare blocks suitable for rebuild, I am interested...
