I want to build 600+hp as cheap as I can form my 440. As far as prepping the block for some serious street use, there's really not much to it! Our goal was power cresting the 500hp mark, a level that is more than enough to move our lightweight Duster in a hurry. Link is: As for cheap: the performance curve being what it is, that may be a relative term. Some carefull de-burring and polishing are about all that's needed to ready a 440 crank to do battle on the boulevards!! I have not ran down the track yet, but seemed to breakin well. Dave Dudek used our 4.
Choose any bore size, any compression ratio, any stroke crank, any length rods listed on this page and we'll include 'em in the kit for the standard price. Is the car a race car or street car? But after another light bore to sleeve was touched all around and the sleeve was taken to. We've been selling our kits for over a decade, we have many thousands of them running in all 50 states, and over 15 countries around the world, rocketing doorslammers as fast as low 8 second quarter mile times, and dragsters deep into the mid 6's! The machined ring has a relief cut on the outer bottom side to accept the sealing ring. All include matching chrome moly heat treated, centerless ground pins. It's a heavier webbing on the mains and the motor mounts ears are much beefier. Like the intake manifold, the carb favors top end power in keeping with the intended application. It made726hp and almost 800 torque! If you bore the block and install new pistons, it doesn't matter much.
Dave, I just noticed the Lynch Road block I just rebuilt has a 2-24 casting date and 3-19 assembly date. Fortunately, these days affordable high-compression forged pistons are readily available from a number of manufacturers. As with the cylinder heads, the induction system is a prime area for an effective upgrade. Because the pistons in this kit are so short, the wrist pin is in the same area as the oil ring, requiring the use of oil ring support rails. I would have a chamber cc'd anyway, just to see where they are.
A further upshot is that these heads can handle considerably more valve lift without retainer-to-guide clearance issues, and come equipped with positive-style valve stem seals for improved oil control. Later 440s suffered a significant drop in the compression height of the pistons, resulting in abysmally low compression ratios. With a bigger carb it went down hill and that's why I suspect the intake wasn't up to par. Like stated earlier, it all comes down to personal preference and how you want to enjoy your car. The only downside to using our Speed Pro pistons was that the compression of this engine with the stock heads and the pistons.
There are still quite a few more pennies to pinch here: Stock 440 block, bored. .

Bought a '75 440 from the junkyard, tore it done, proved ot be in pretty good condition, honed it at home and installed new rings, bearings and rod bolts. Even the highest performing factory 440, the 390 horsepower Six-Pack or Six-Barrel version, had a relatively mild hydraulic flat-tappet camshaft and non-adjustable rocker arms, ensuring years of smooth, maintenance free operation. Here is two examples we built with prices. Rods are our superlight H beam 6.
The rockers must be assembled on the shaft as shown so the rocker tips line up properly over the valve tips. I have read about these things making insane power with minimal effort. As the engine with the biggest factory displacement, the cubes are already there for ample power production, and the rugged bottom end components endowed by the factory are built to go the distance. Can you get the right rocker arm ratios? This is the largest kit which is still able to safely use a factory style internal oil pickup. Using a piston as a guide, the clamp is tightened until the rings were compressed just under the bore of the cylinder.
I know people like a date correct block for their car but it still doesn't make the car worth what an original motor would. Your actual bobweight, depending on the weight of specific components used, may be higher or lower. A stock windage tray and 5-quarter stock oil pan are used, although Sephton readily admits that a larger pan might be nice for this level of engine. If you're running a zero deck combo, you also get the quench. Why would there be, the material weighs the same wether it's vast ro forged. To determine if you have a 440 block on your hands, and to figure out what year it is, look at the machined pad to the front of the intake manifold on the right side. Whichever engine I build will go into a '70 Barracuda that I'm turning into a big block 'Cuda.
Stroker Kits from 440 Source!! Obviously there are better pistons available but again, assuming you wish to keep cost down maybe to put into heads 1. To complete your Registration you will have to click an activation link in an email Immediately sent to the email address you gave. Dave, I just noticed the Lynch Road block I just rebuilt has a 2-24 casting date and 3-19 assembly date. I'm not trying to be obsessive-compulsive about my restore. The big Chrysler 440 doesn't pop into one's head straight away as the most traditional hot rod powerplant, but it has been around since 1966, and was on the scene in 413 and 426 wedge form before that. While the 440 ceased to be in 1974, the mold was cast and the wrecking yards were chock full of these race-ready engines. I also have a 650cfm 4 barrel holley carb, other than that im not sure what parts to go with.
If thinking about retaining the stock pistons, I would advice not to. Check it out at: Check out the new January 2012 issue of Mopar Muscle Magazine. You can get the power output you're talking about with more cam and stock heads with work , but it gets to be a pain to deal with everyday, if you want it to live on pump gas. Anyone can pick parts out of a catalog and assemble a motor, but proper engine design requires thought and research. Depending on the block used, many of customers find this kit drops right in with no modifications whatsoever! With a very conservative 32 degrees of timing advance we started the first of our 20-something dyno pulls.
Just how much difference do the aluminum heads with the better compression chambers make? Now, this is a lower compression around 11. That's assumming hood suspension, fuel system, etc. All clearances hovered right around. My friends B-body, I built the shortblock. What sets Diamond Pistons apart from the other custom pistons shops is their Mopar knowledge. As with any engine, good quality aftermarket rod bolts and bearings are recommended for anything more than just a stock rebuild. Where things get interesting is that you get to choose different specs like gas porting, oil rail supports, custom coatings, even ring height and width.
