Head & cam selection...346 iron w/solid roller or Indy EZ w/XE285HL

The thread on a head and cam selection for a 440 got me to thinkin' about some old 2014 dyno tests we did on a 8.9:1 compression 440 with 2355 pistons. I thought I had burned the old dyno sheets but there in the corner was a dusty yellow folder with a stack of 80 dyno runs.

So then we have two dyno runs both with the same short block.....
.....#1 top end) 850 Mighty Demon, 2" 4 into 1 Super Sucker, on a single plane Mopar Performance M1 & solid roller 277 @ .050, 105 LSA, .608" gross lift w/1.6 rockers, 346 iron heads flowing 295 cfm @ .600" lift. (Edit: 8.9:1 compression)

.....#2 top end) 850 Mighty Demon, Edelbrock Victor, Comp XE285HL 241/247 @ .050", .581" gross lift w/1.6 rockers and solid lifters @ .005-.006 hot lash, ported Indy EZ heads flowing 350 cfm @ .600" lift. (Edit: 10.4:1 compression)

Which will make the most top end power? By how much? What is the maximum power level?

@ 3,500 rpm
.....#1 made 537 lb-ft.......roller cam/small heads
.....#2 made 508 lb-ft.......hyd flat tappet with solids/big heads

@ 4,000 rpm
.....#1 made 530 lb-ft
.....#2 made 527 lb-ft.......somebody is catching up

@ 5,000 rpm
.....#1 made 502 HP
.....#2 made 518 HP hmmmm

What happens now........will the trend continue?

@ 5,500 rpm
.....#1 made 552 HP
.....#2 made 544 HP.......guess not, but how close will they stay?

............................#1 HP.........#2 HP
@5,800 rpm...........571............544
...5,900 rpm...........582............564
...6,000 rpm...........594............581
...6,100 rpm...........587............576
...6,200 rpm...........600............574
...6,300 rpm...........596............583
...6,400 rpm...........602............588
...6,500 rpm.............................595

Funny how the different cam and head combinations work themselves out. Gotta have a lot of respect for the XE285HL with the right combination. Here it went to 6,500 rpm when it is rated 2,500-6,200 rpm. Not that that really means anything I guess.
