If you compare our 410 against louis' engine, his had more power after 4000rpm everywhere. It's not apples to apples because he had an M1 on but most everything else was close.
I did a 440 sb mopar for a guy (actually I re-did it after someone else ruined it), flat tappet cam, indy cnc 360-2 heads, indy intake, 10.2:1, 950 annular carb. I spec'd him a cam, had 106lca, and some edm'd lifters and broke it in. Started to dyno it, after 3rd pull we had 602HP and a nice WIDE power band. Then cam went flat. Only exhaust lobes!! Found out the lifters had not been heat treated properly!! So customer wanted more drivability and less idle lope, so all I did was clean it up and reassemble with same cam but on 112 lca and boy it lost alot of avg tq and hp but peaks were up by 10! So I'd say that was a surprise. I could have used different lobes, smaller lobes and made better avg's but he NEEDED to see at least 600HP and we ended up making 615 after tuning. That was at 6400rpm and 91 piss gas. True driver, not a mix pump and race gas deal.
I've also seen the same thing in BB's...same thing. Cam went flat after break in (this time it was improper spring package supplied by customer as it was assembled by him as well) but before it went flat we got 595 HP but was peaky.
So customer let me pick the cam, and went with certain lobes I like to use from Comp, and lca was 110 and went to 107 and duration went from 252-258 to 256-258 and it made about 20 more avg tq and 25 more avg hp in the same rpm range and actually peaked at 612 after tuning which the other cam may have as well...
The BB had ported eddy heads, 490cid and indy intake. Compression was 10:1.
