Yeah like most of US all think or knew
the Hemi didn't do as well till higher RPM
after 5,000 (short intake runners)
the 6bbl is a torque monster down low, but only up to about 5,800
440-6 hands down way better Tq #s' down low
(the Org. 440 6bbl Edelbrock dual-plane setup w/2300 2bbls flowed like 940cfm
factory rated, not anywhere near the total 1,350cfm, of the carbs cfm value)
the Hemi in a WOT drag race situation can perform way better
at or above 6,000rpm when the 6bbl falls off
More cid doesn't hurt the 440-6bbl either
the 440-6 had a lil' more compression 9.4:1(ish) vs 9:1 Hemi
440-6 be great with a 3.91:1 street gears & 3,800-4,000 stall
same spec. Hyd. roller cam used in both engines
that cam they used did well on both
Hydr. Rollers like 0.550-ish lift, (not sure what rockers/push rods)
I don't remember what they said, in duration either (230-ish (?) @ 0.050)
I know it wasn't real-wild cam,
IIRC they said installed at 107*-108*
"allegedly both had stock 'unported' cast iron heads"
906 w/"alleged" stock valves on the 440-6 "allegedly"
both were less than org. stock advertised compression ratios
The 426 Hemi was an early version of the MP 426 Crate Hemi, 20 years ago
except for the
Stave V (IIRC) Holley square-bore 2x4bbl 4160 carbs/dual plane manifold
(I assume 600cfm carbs, I don't remember them saying the cfm or model #'s)
instead of the Org. style stock intake, with 2 small 525 Carters
it'd be great with like a 5,000 stall & 4.56:1 - 4.88:1 gears
(Frieberger said he has 5.13:1 IIRC in his 70 SB, it was a pooch with 3.73:1)
both had aftermarket distributors & ignition,
both had -6 AN fittings & lines feeding everything
not the lil' 5/16" restrictive org. steel fuel lines
both/all, a win win
both had dyno headers, not the restrictive 'cast iron hp manifolds'
(there's probably 25-30hp right there)
mid 550+ish HP not too shabby, for stock-ish BBM builds
