I just purchased a 440 engine, I want to reach the 10-11 second mark but I only have $2000 to spend. Any advice would be apreciated.

I hope you're putting it into a very light car. IMHO, I think 10's are out of the question. If you buy almost none of the parts new, and you're good at haggling for good prices, do all the work yourself, you MIGHT be able to get into the 11's. Keep in mind, getting that kind of performance is more than just an engine. Even if you built a 440 for 2 grand and put it into say, a Dart, you still have to build or find a suitable rear axle and transmission. Nitrous oxide will definitely help, but with that kind of price limitation, all I can say is good luck to ya'.

Okay, here is what I would do if I had 2 grand to rebuild a 440:
Clean engine block, $50 Bore & hone, $150 Clean, check, chamfer & polish crank, $30 Summit Engine rebuild kit, $486 (includes forged Speed Pro pistons, rings, all gaskets, main, rod, and cam bearings, hi-volume oil pump, freeze plugs, Plastigauge and assembly lube) Summit timing chain set, $42 MP cam & lifters (.484 lift), $148 MP windage tray, $28 (cheap horsepower) Install cam bearings, $40 ARP rod bolts, $40 Balance rotating assembly, $150 Rebuilt water pump, $20 Check & Resize rod big ends, $60 Install pistons to rods, $48 Valve job, $150 New MP valvesprings, $105 Bronze valve guides & installation, $100 Surface heads, $60 New valve seals, $25 Used aluminum intake manifold, $100 New Holley 3310 750cfm carb, $220 Final total is $2,052. Figure about an extra hundred more to cover hidden costs like shipping charges and taxes. Actually, that would make a decent street engine for the money, and I wouldn't be surprised if you made 375 horsepower with these parts. Hope this helps. ------------------ My Pro Street Duster Web Sitewww.mindspring.com/~dusterdave |

Duster, are you basing your 375HP estimate on net or gross HP? I ask because your suggested build up sounds a lot stouter than a stock 68-70 440 Magnum, and that has a gross rating of 375HP.

Actually, I was originally going to estimate 400 hp, but I decided to give a more conservative estimate. Although this engine would appear to make more power than the old factory 440's, I've heard that those factory 375hp ratings were a little optimistic.

Moparman Do you have 2000 to build the engine or just 2000 to build the whole car. If you have 2grand to put into the motor you can get into the the 11,s but the tens are tough.But you need a light car, say about 2800lbs,.A bare bones 440 would be mill the heads throw a big cam in it put it in light car and go.But it wont last to long.My bare bones 440 lasted 100 passes before it spun a rod bearing.I had a$1000 dollars in that bare bones 440.
engine $300 cam $150 mp484 timing chain $ 50 intake/carb $200 swap meet distributer $150 valve job $120 and.030 springs $ 80 933,s windage tray $ 25 headers $ 50 1.75 homeportheads.$ 00.Lot of beer money/time You still have to add car ,posi and slicks. This combo gave me a best of 11.74et in the 1/4 mile.My new motor is a bare bones up grade from the bare bones 1. Bare bones 2. clean engine block/free regrind crank $120 cam $150,509mp molly rings $ 80 mill,heads $120 100 off bottem hone stock/blk. $ 40 hone and stones. ridge ream $ 00. free rent at auto. bearings $ 80 rod and mains arp rod bolts $ 40 gaskets etc. $ 50 Bare bones 2 has given an Et of 7.12 @ 98 in the 1/8 mile witch is close to the tens.I havent run it in the 1/4mile yet.The car is a73 Sport stripped for weight loss@2800lbs. I have $3500 into the whole combo but theres a problem,Iwant to go faster,6,s sound better than 7,s and I am so close.Now I want a new converter,$500 how about another cam $150.What about those new Eldebrock aluminum heads $1500.Does this ever stop!

Put most of your money into your bottom half. Make sure that you have a good rebuild as a base to build on. Get a piston that will give you the CR that you will need down the road. Get a basic valve job for now. After you have a good base to start with, you can work up the top half as you get the money. You might have a 14 sec. car, but it would be a ball to see it go to 11 or 10s as you work it.

All I did with my old 440 was punch it .030 over,used a set of cast pistons(Silvolite)moly rings,new bearings,296/557 Mopar cam and all the new obvius stuff like timing chain,retainers,locks,that type of thing,I found a used Edelbrock Torker intake and used my old 750 Holley dbl pumper carb.The heads I put the oversize valve in and used the Crane roller rockers.The crank and rods were miked and were ok ,so I just re used them with new rod bolts.The block wasn't decked or any other machine work was performed.I didn't even use a torque plate as at the time I didn't have one.I had to build this engine in a week as I damaged my 383 and was heading to the bracket nationals.That 440 lasted 7 years,and ran 11.29@117 and I just tore it down to refreshen it and install new forged pistons and a bigger cam.I think total we had about $2200.00 in that engine.I wouldn't do it that way again,but a 383 and 440 bottom end is pretty stout from the factory.

First, I would look under the heads and check the bore, If there isn't a REAL noticable ridge in the bore I would not worry about bottom end(unless you have cast crank and bad bearings) In this case(if you have hi CR pistons I would buy the whole Ebrock Total Power Package. This includes cam, lifters, manifold, carb and a really good set of heads. I called Edelbrock and there motor had 9.5 to 1 cr, but it was a motor built in the late 80s that has been flogged several times for dyno test, Maybe it is in comparable shape with your motor so it will put out 470 HP too. By the way, From Jegs you get a man., carb, cam w/ install kit(lifters, lube, ect) for like $550. The Heads are gonna be like $1300, Throw in headers(from Hedman for $95) that = like $1950(or something close to that). That leaves enough for a junk yard electronic ignition. By the way, doesn't Jegs have free shipping for orders over $100? Its all about what you want to do! Did I mention 470 HP? Also reduce wieght in the vehicle(cost money). I think you could have a cheap high elevens street vehicle(say if it is a 3600lb car). Have fun!

Ok, don't worry about the bottom half. Put all your bucks into the top. NOT. If he don't tighten up the bottom now, he will be doing it later. Get the CR you need now.

Moparman 1971, If the engine you acquired was in running condition, I can give you a recipe that I used.
Stock 1972 440 added hemi valve springs to go with mopar .509 cam and lifters a Holley 750 model 3310 on an Edelbrock Torker single plane intake 1 3/4 Hedman headers 2500 stall convertor, manual valve body 4.10 gears 275-60 hoosier QT in a 3250 pound including driver 70 cuda I went a 12.13 @ 110 best. THE QUICKER YOU GO THE MORE MONEY IT COSTS I WON MORE RACES RUNNING 13.50'S WITH A 400 WITH A SMALLER CAM. HAVE FUN ABOVE ALL ELSE! |
