this is a 440 build Im undertaking with a load of spare's I have. this is a bucks down budget and Im wondering what power it might make

std bore 72 block, the only mods are a 1/2 pick up and .015 off the deck.
std crank with std bearings
std LY rods and std cast flat tops with 1.990 pin height
915 heads with 2.14s and 1.81s 75cc chambers
.020 shim head gaskets
heads are tickled but not what Id call ported, but gasket matched in and ex ports.
.509 cam and dutile rockers with ball/cup push rods.
torker II with a 750 hp carb.
1 7/8 hooker fender exits
windage tray and 7 quart sump

what do you think of that for a budget combo?

also Iv got a t/a 3000 verter and t/a rev patt manual 727 for it
 
Unless the car's a stripped race car I don't see it running much better than mid-high 12s unless you've got major gear and no weight. You could do much better on the cam choice to work with the low compression pistons IMO.

Don't see any mention of what its going in, or what gear, if its going in a 3800 lb. car with 3.23s you'll be lucky if it bust out of the 13s, now if its going in an A body with race weight around 3200 lbs. & gears then low 12s shouldn't be a problem, It'll go in the 11s at that weight, i see a couple things that will hold it back, the stall & intake, with that cam i'd run at least a 9.5" 36-3800 stall at minimum, 42-4400 would work better, at least a 4.10 gear, even 4.30s with a 28" tire. A street Dom. intake or an RPM. The cam IMO is fine, you can run in the 10s with that cam, its been done many times.
 
Here is the car, seen here in a cheap black primer. All steel body & it weighs just on 2850, its got 4.56s 31" tires, I do have a t/a J converter 3800 in another trans and an M1 with 950hp carb but I was saving that for the 448withSRs build & I really thought that the J and 950 would be too much for this engine combo, this budget build engine is more a test mule to tune the 4 link and brakes etc etc

if the mule ran 12s thats ok but if it turned 11s all the better

I would definitly use the J 3800 stall, the M1 might be a better choice over the torker, I would say the 750 will be about the best, but it wouldn't hurt trying out the 950 just too see how it compares, the car is "light" no doubt, if your not hefty lol, that set-up should see high 11s all day long if your closer to sea level, 1500 ft. or lower.

What is the accual compression?

Just to give you an idea on this, I've built a few BB A bodys, my last was a 75 duster (in my sig), before any upgrades, It had a FT 451 low-deck no thrills combo, Ross pistons (9.73 compression) & "un-ported 906 heads with the stock size valves, My race weight was 3100 & change, bolt-ons, M1 with a swap meet 750dp, XE284H cam, ductile rockers, 4.10s on a 28" tire, The converter was a low budget PTC 11" 3000 stall, once i got a few things worked out, better 60fts., I ran a best of 11.12 @ 120 at Ennis raceway, had a 1.57 60ft., i shifted at 5600, the car worked well, there is no reason that car should not see 11s period.

Had a 73 Swinger all steel & the big *** bumpers, car was abit heavier but never weighed it, basic 440 with KB FTs, .509 cam, SD intake, 850dp, 3.91 gears, 28" slicks, 4200 stall (boss hog), so low quality converter, Now the clincher, The Alt. was 3700ft., in most cases the DA was 4800-5200ft., Car ran 12.4s @ 108 back too back, At ennis it would have run 11.8s easy.

My last car was a 71 Swinger all steel, dropped in a junkyard 360 magnum, RHS heads (stock valvetrain), very mild re-ground cam, Crosswind knock off RPM, 650dp, 3.73 gears, 27" DR, PTC 11" 27-2800 stall, 904 trans, I'm guessing the cars race weight was 3200, The tracks Alt. is 1400ft., With DA around 24-2600, the car ran 12.5s @ 105, I shifted it at 5100, it was out of steam at that point. So if all your 440 will run is low 12s over this piss-*** SB i had, I'd go back to the drawing board, MANY on these boards said i would never see a 12.99 with my last car, I let off at the 1000ft. mark & ran a 12.70 lol.

These are just a few examples, it really doesn't take much to run in the 11s with a BB A body.
 
the 915s are shaved to 75cc, this calculates on the eagle cranks website to just on 10 to 1 comp. thats as high as Id take it on these pistons.

our track is not close to sea level but offen on some evenings paticularly this time of year we see perfect air
 
Im willing to bet the 11.50s or better If the car works thats basicly what I run in points it would run 11.52 loading the cunverter hard on a cool night. or 11.70s in hot wether leving at 2000rpm..good luck It may suprize you.....Artie:hello1::hello1::thumrigh:
 
Yeah, I'll revise that to 12.20s as it sits. Maybe more with the suspension more than baselined.
Cool car.
 
talking of suspention the car has calvert 90/10s up front & competition engineering 12 way ajustable coil overs out back

front fenders removed, alloy trunk, dash removed, fully tubbed with a 10 point cage.

the brakes are early 80s aussie Valiant slotted rotors & alloy calipars up front and the 9" has custom rotors with aerospace component calipers, saved alot of unsprung weight there
 
My 74 Duster.
440 8-1 comp
Performer RPM intake
780 holley
509 cam
Very well built trans.
3000 rpm stall converter.
3.91 gears on a 8 1/4 rear.
Runs 12.20's all day long off the juice
You have a lighter car so you should go faster.

Changed to stage 6 heads and ran 11.70's

Man you guys have some slow running BB A bodys :D JK

Not bad with low compression.
 
my old car was a 74 cuda - similar build / 440 9.0:1 / old school heavy TRW flat tops / 509 cam / 902 iron heads / 3000 cheapo converter/ 410 gear / went 12.20 .
