LA versus Gen 3 race

Personally being a engine machinist Im not a fan of the gen 3, it has such a small bore, the block is extremely heavy compared an la, it's a ***** to torque the main caps lol. It sucks to load up under the boring bar .
But I will say is stock hemi vs stock LA
Block, hemi is much stronger
Heads, well they're hemi enough said.
Rotating assembly, new hemi much better.
But again personally I like the simplicity of the LA. I don't know anything about the W heads or R blocks to comment about it, however I know they're fast. If I was going to build a hemi though I'd make it simple, big tall tunnel ram, carbureted and high compression. The block is start with would be the truck specific 6.4 hemi.
I prefer low deck big blocks over both though.
