Default Engine build advice please.

No such thing as a daft question they say, so here goes.... I'veJust removed the main bearings and looking for replacements, are these 0.25 over size or standard size mains?



Im going to build a classic center thrust EJ20 with new age rods, will these conrod bolts fit? For a 400bhp build would upgraded bolts be needed?

Another daft question.... How do I hold the crank in while tightening conrod bolts? I thought about running the bolts down while it was in the block half but I'm worried about damaging the bearing surfaces

Thanks

Steve.
