well my "new" 440 is almost done. it is a 78 block with the thicker mains and bore supports. filled with 7LB each side. mancini 3/4 girdle iron mains. 440 source stock stroke crank (boy are they hard to drill into) K1 rods JE pistons 110LS 263 265 .635" lift with 1.6 rockers in at 110. (well 109.5 anyway) old indy heads 270cc intake runners. 2.19 intake 49cc chambers 335cfm flow, M1 intake single plane, dominator 1050 carb.
all the above parts split my 73 440 block. i want it to go a couple of seasons this time. no roller till it lasts a while.
going in my 76 duster (again) this one better last longer than a season. this is the last stock block 440 i will do. i have two 400 blocks now for later (i am collecting )
sofar best time slip is 10.20sec. cam at 108 last time
now for spring

got to watch those stock blocks. I have a 440 that has served me very well, Just .030 over and with 440-1 and a small roller cam, went 10.20's on motor and 9 teens with a plate, LOTS OF CAPWALK....LOL stock caps with ARP studs. Alum rod...
Keep your motor OUT of detonation and should be ok...Good luck and keep working on it, sure you hit the 9's soon

I am using 440Source crank also in my 63. Thats one very nice looking Duster. Got any more pics of it ? Ron

Nice Duster! Sounds like it runs good too.

in the spring when it is back together i will have to get a shot of it on here with out the ugly 95lb drinking bumper on front. shame the new bumper at 7LB has been offset by 14lb of filler and the heavy gurdle/cap addition> but i am welds matching front rims with front runners and will do the aluminum front pump.
maybe later tory can get rid of my k frame.

Nice car. Sounds a similar set up to mine, you have a bit more head than me but i suspect i'm a little lighter.
How many passes on the old block.
Mick

the block cracked someware above 60 passes. just one season. broke it october a year ago.
i was 3170 me in it.
i know people with ported 915 all out roller running in the 9s but i do not really need to put a roller to see how fast it will go. low 10s is fun, good respect and not a all new setup to do low 9s with chassis mods.
bang for the buck then is my stock engine 2000 zx12 ninja running 9.25s in cold mine shaft air at cecil md.
i think with my M1 tunnel ram two 770cfm holleys and roller it would do mid 9s but sofar i do not feel the need to push it. i have had trouble with issues. first was a broken spring caused a intake head to brake and mess up 3 chambers. the next fix was not a good one then a ring land broke and that busted a cylinder. 5 years later i get it out again with the 73 block same cam and heads 3rd pass 10.20 at cecil looking like we have teens maybe 0s later on. one year later from running at numidia at 1100ft all summer i go to cecil in october with 10.42 dial on the window and pull a 10.27@131.78mph with a 1.55 bog 60ft. i fix the issue by staging higher till i get to put the yellow cam back in the rear accelerator pump and pull a 1.48 60ft. thinking i got the teens. but not running as frisky as first pass and only got a 10.24@129mph and oiled the track from the 1/8th to where i shut it off. all the water went in the oil when the block split up the mains and pushed a oil pan gasket. it did not ruin anything but i am sick of something going wrong every year i finish a season. maybe after two years of not braking i will step the power up and see what happens (i would love to) i know the car is fun. more scary to me than the bike and the bike is faster.

"dmking" do you race at Cecil alot ? I only ask as I usually go there when I run my 63. But I mostly run Test & Tunes. Hope to get there a few times this year. Ron

i d get there. i imagin it will be the first place i test it when they open and the track gets good sun so i do not look like i am trying to wreck it.....
if i go on a friday it is with the bike.
