TA Performance used to carry the hi perf for the 455. Not sure about the 300.

Assuming you have 4.0/4.6 block and you need bearings for that application check out King Bearings.

www.king-catalog.com/Catalog/Engine/10079073 (4.6 litre)

If you have a 300 block and want to use 4.6 bearings the link includes dimensions for mains bore size. Width of the bearings may be an issue, especially the flanged shell.

Thanks Jukka, Even more, out-there. I'm machining an SBF, 4340 raw forging crank, to fit RV8.
