500hp & 600hp Bench Racing thread

My 2 cents s in the small blocks.


I’d follow this as well. A lot depends on the cylinder head on hand which can change the camshaft selection. Currently the 340 I’m working with is on a 108 LSA, well ported aluminum heads and a 2.08/16.0 valve set up. It’s not a 500 hp build, though I expect a good street machine engine.

I’m doing this now (parts collection actually, I have most of it) the cam I have for this is a Ultradyne solid FT @ 272@050 intake. On a 102. It’s a NF lobe. I’m sure it’ll sore past 500 hp. We will see what the dyno says.


Can’t wait for the dyno results
