OK, I know alot of people do this, so I figure it's my turn. I just sold one of my cars & soon as I get the check I'll be ordering the final parts I need to install my new 440 into my 74 Duster. Engine specs are. .030 over 1968 440 block, KB h.u. pistons are .002 out of the bores, close to 10.4 to 1 compression. untouched edelbrock 84cc rpm heads. Lunati "Voodoo" hydraulic 226 & 234 @ .050 & .494 , .513 lift. Edelbrock # 5440 dual quad intake manifold with 2 Edelbrock 600 cfm carbs. Shumacher a body headers with 2.5" pipes all the way back, 727 tf with trans go stage II valve body. a 2500 rpm Hughes converter, and either 3.23 or 3.91 gears with 27.5" street tires. the car weighs 3230 lbs now with a 318 & 727, so I'm guessing it'll be a couple hundred lbs. heavier with the 440. I am a realist so please be as brutally honest as you can. The car is primarily a street car, with 1 or 2 trips to the strip a year. I think I have thought this package out pretty well, but if anyone sees any gross mismatch between parts, please let me know ! Thanks in advance !
 
Wild guess.. 13.5 with the 323's. 13.0 with the 391's. I think the dual carbs will be too much. I would run a 850 C.F.M. single carb and beef up your converter to 3500,then you would be more like 12.20's Just my 2 cents.
 
From my experience with 440ies in these cars, is to try and get them to hook-up! I remember taking out center cones on the track. That was not fun.
 
I pulled out my dream wheel and plugged in a race weight of 3600 LBS and I plugged in a conservative 1 HP per cubic inch of displacement (440) and came up with a perfect world 11.73 ET. I would say your gears would increase the ET by .3 seconds (12.03). I would say your converter is going to hurt you about .5 seconds (12.53). I would say if you run street tires you will gain another .5 seconds (13.03).

I see 3 things that are going to hold you back, the converter/gears & headers if your looking for the most out of your combo, It should go mid 12s though, but with better headers, a 4.10 gear & at least a 4000 9.5" converter, it'll get you in the 11s pretty easy. As for the 2 4s, it'll run good with them, but a single carb would do better with what you have "now", but if you step things up like i listed, the 2 4s i'd say will run better.
 
What's the suspension setup? shocks alone dropped .1 off my 60ft and .5 off my ET.

If it hooks I'd say 13.8 with 3.23's . . . maybe even a 14.0
with the 3.91s and a good leave I'd say 12.70's Point I'm trying to make here is 60ft is everything and even with traction that small converter and weak 3.23 gear is not gona be ideal.
 
i concure with not enough convertor and and too much carb, i had a similar setup in my 68 Barracuda 440 .060, zero deck, 84 cc heads (edelbrock aluminum), 577 lift, 260 @50 comp cam, victor intake and 850 demon, with tti 2.00 primarys, 456 gears with 28 inch slicks, 3200 stall, ss springs, etc etc, unfortunenatly, mine also would not hook, even with slicks at 9 psi, and the best time i could muster was 7.60 @92 mph ( about 11.40 in the 1/4), and the car has a full interior, so my suggestion , is lose the tunnel ram, i had one and i didnt like it!
just food for thought,
 
bcuda452, It's not a tunnel ram, it's a medium rise dual plane, dual quad intake. I put this same intake on a stock(rebuilt) 440 in a 70 Coronet & went from running 13.6s @ 103 mph to running 13.1s @ 107 with NO other changes. throttle response went from great, to unbelievable, all my Chevy driving buddies could not believe it was a stock long block (375 horse cam, & 1975 400 heads) with headers. & the only reason I used the 400 heads was to get the compression down & so I could run unleaded gas. The Duster runs 14.0s @ 97 right now with a mild 318 & 3.55 gear. I guess I was wrong in thinking the 440 could pull a 3.23 gearset, So it looks like it'll be the 3.91s thanks everyone for your input !

Unless he's in Denver, that car will see 12s as it sits easy, A buddy of mine yrs. ago (mid 80s) had a 68 charger fully dressed, .030" over 440, .509 cam, TRW 6 pack pistons, mildly ported 906 heads, Torquer intake, 850dp, 3500 stall, 3.23 gears, yes 3.23s, the engine was built for 4.10s, with slicks & "stock" suspention car ran 12.4s-12.5s. 60fts. were not good, like 2.0s
