New life for an old 340 (stock stroke)

Would need to know the whole combo to understand this one because I have seen in certain situations a really large spread and lower than expected peaks points to one piece of the puzzle being really out of wack effectively hamstringing peak torque/hp production.

No magic in that combo, but it did make a bit more top end power than I expected.
About 10:1, like I said already.....ported 346’s, RPM intake, ootb hp750, 1-7/8 Hookers, stock crank and rods, milodon pan and tray, Comp xs282s with the older blue 1.6 Hughes rockers.

I wonder if you took that same cam you had done for the 340, ground it on a 108 instead, installed it with the same amount of advance as you did the 113 cam..... changed nothing but the lsa...... what the difference in peak power(tq and hp) would be, how much the tq and hp spread difference would change....... and which one would show a better “score” under the EM scoring criteria.
Somewhat of a proof of concept test.

When that was done several years ago with a sbc, the tighter lsa was the winner on that build.

Not to totally highjack the thread.......
It depends on what you’re doing as to whether a 14-1600rpm spread is an issue or not.
In a drag car, thats plenty.

When I had the 448 in my car, the on track operating range was 1500rpm(5300 stall, 6800 at the finish line, and the 383 was 14-1600rpm(5400 stall, 6800-7000 at the finish depending on the weather).
My 383......stock 400 cast crank, stock rods, TRW L2315’s with flycuts, unported 906’s, rpm intake, hooker 1-7/8”, ported 850 carb...... peak tq at 4300, peak hp 6200(1900rpm spread)......106lsa cam in at 102.

The other day I posted a dyno sheet for a bracket race 416 with bowl ported rpms and a solid cam...... 106lsa, in at 102...... 1600rpm spread.

918hp 14:1 572 with cnc 572-13 heads and a .825 lift cam on a 112...... 1200rpm spread.
