Warming a 440... Bench engine building.

[steveo]

carrying on from my post yesterday , been searching for said engine build up I mentioned in one of the mopar mags from years back with a 268 compcam, ( not found at this time ( did give loads of them away though ) , will post here when & if I locate it , )


heres a few other street type , none radical 440 builds , from engine guys in the US .
as we all know there are a lot of variables , from one guy building a motor to the next & one dyno to the next & this is crank power , not rear wheel , & we all know proof is in the pudding , as to what MPH you run in the 1/4 vs weight of your car . have a read through the specs & info , lot of interesting reading ,

this might give some ideas , what can be achieved with out going to expencive aftermarket parts . torque is what you want on the street

this is close to the 268 build I was mentioning below

By Biblical I mean 3mpg gentle cruising with a 512 and 4.56 gears.....much worse when you get on it.......

maybe you should consider LPG

100+ RON and 2/3rd the cost of standard unleaded...

2 or 3 impco 450s bolted to holley base plates

one of those take the lid off inlets with a huge open plenum

3 regulators and a bloody big gas pipe

the americans would laugh and point but the aussies and canadians would be nodding in agreement

if you are only racing i don't see why you could not use propane direct from BOC and not pay road use fuel duty

that would make it 1/4 to 1/3rd of the cost of race fuel

Some interesting stuff there.......closest to mine in the real world was this one......

440 bored .030=446
KB 237 pistons .003 deck height
Forged crank .010 under
Eagle 4340 H-beam rods
Comp is 10.25:1
Eddy heads 84cc with stage 1 and bowl blend
Straightline Cam 234/242@.050 540/525 solid with 112 lsa (4* built in) installed straight up
6-pack aluminum manifold with stock carbs. (Using ProMax stuff)
Comp pro-magnum 1.5 rockers with 3/8 Smith Bros. pushrods
TTI 1 7/8 headers with 3" X cross-over exhaust to the tips
MSD 8546 dist.
MP MSD 6AL
Dana 60 with 3:54

491hp/535 torque
________________

My motor was almost identical cept for an 850DP so loss of some top end hp over 3x2's....Eddy stage 1 heads were a bit better than my 2.14 906's, but the cam was .100" less lift.....mine made about 485hp to weight and speed. The biggest downside to my set up was not enough CR for that .650" cam, although it all worked well and the numbers on the track were good, my cylinder pressure was non existent me thinks, which is why I could run 38 total N/A or with N20 on 4 star....remember that stuff!!!

Bottom line is, although shown in one of the builds, I can't see your gonna make 450hp with stock 2.08 heads....The heads are crap! and only flow around 210cfm.....I was only at 430hp with the stock 906 heads = 11.23 Hauser heads made 50hp bolt on = 10.7

Ah ! I always forget how far further you are up the mad-car chain than me... yeah. 3mpg is biblical.

those were a good set of heads from hauser .
38 degrees , with 4 star & iron heads crikey , with out pinking / detonating , yes the cam must of had a lot of duration , 650 lift that's a radical cam .
, yes I remember 4star , going off track a bit , I remember when I first got the charger , it was £1.70 a gallon I think , don't even remember them selling it by the litre then any of the younger members reading this , that was about , 38 pence a litre , YES PENCE , back then .
I remember , just about / sure I do ) the pumps selling 5 star too , just ! I wernt driving then I was a kid in the early 70s .
back on track , I did inquire some years back , to muscle motors in lancing , they supposedly had a cnc program , for the 906 head , they said it would flow enough for 600 horse I think , in a 505ci motor , thought this would be the ideal head , i'm not a fan of ally , for various reasons , , till I saw the price of them , did not want to risk that kind of dough on 45-46 year old castings , I believe they are prone to cracking , , who knows what they will be like , after a few months / years of heat cycles , with that amount of work being done. apparently the CNC program was for , FAST ( factory appearing stock tyre ) class . where those guys are money no object .

Hi Les

Our 426MW was rebuilt to std specs a few years ago and made 450hp on Kenny Coleman's dyno. We only managed 13.5 @ 106 due to lack of traction (and lack of driver ability!), but that's almost exactly the same time as we got in the Sport Satellite with the 440 that Clive Bond (Ultimate Race Cars) built back in '87. That had (& still has) stock iron heads with very little done except the usual 3-angle valve job, but I would imagine we weren't far off the same power, as the mph was the same. Perhaps a bit of a naïve assumption but I'm sure with a bit more cam 450 is achievable

Gonna get it rebuilt again over the winter with a newer cam (to replace the old .484 'purple' jobbie) but we'll be keeping the heads, and getting it dynoed, so we'll see what's achievable with stock heads and a fairly mild build (750 vac sec, dual plane, 10.2:1, cast manifolds)
