Each flat-top slug features deep valve reliefs, coated skirts, and Total Seal rings. Each journal, rod and main were inspected, measured and if needed adjusted to meet the kind of tolerances needed for a high-performance motor. Maven This supports the Maven widget and search functionality. Some builders will recommend a high lift and low duration cams. I'm putting the top end together now , Engine Quest heads with bronze valve guides, 2.
Aluminum heads reduce the weight of the engine by about 50 lbs. The 3mm oil ring easily fit without protruding into the piston pin bore. That, combined with overly large main journals caused the 360 to gain a reputation for spinning bearings. It will be very frustrating, however, if we can't get them. By the time you do all that it's almost as cheap to go with a set of aftermarket connecting rods. Parts and information are easy to find, and since it's a fairly popular engine, they are not too expensive.
Final machine work for our 440 was done in the Dart facility. If anyone out there has made this swap email me with your recipe, any help to save time and money will be appreciated. Non-consent will result in ComScore only processing obfuscated personal data. And most importantly, keep you from buying the wrong parts! But then, it should be for a 454ci engine!

Interestingly, the actual peak torque value only changed a little bit, but the horsepower jumped by 56 points. The dyno would tell the story here, and this big-inch small-block proved its worth. Even with the very long stroke, the crankcase clearance was a minor issue due to the small 2. With a dual plane intake, this engine would lose some peak horsepower but gain torque that would help accelerate a medium weight street machine somewhat quicker because of the torque increase, even with the reduced horsepower.
In fact, anything deeper than a 3. Paypal This is used for a registered author who enrolls in the HubPages Earnings program and requests to be paid via PayPal. Beneath the intake manifold, we can see the external coolant lines which route coolant from the front, center, and rear of each head. Messages may also be sent to bluecutvalley2002 at yahoo.

A modest notch at the bottom of the bores was all that was required to make it fit.
The Mopar 360 never came from the factory in a high compression version. The 318 is a great engine, but it gives up too many cubic inches in a purely performance application. The engine seems to have been designed to gain more cubic inches, and in How To Build Big-Inch Mopar Small-Blocks, author and Dodge Motorsports and Mopar Performance Parts specialist Jim Szilagyi, explains how! Google DoubleClick Google provides ad serving technology and runs an ad network. If you have significant experience in building engines, then you may decide to deviate from these combinations and perhaps even improve the power. Thanks again to everyone that has replied thus far. I have a 73 power wagon W100. When an engine is in balance, these heavy forces are countered by the counter weights of the crank shaft.
If you want to make big power from your Mopar small-block, this is the book for you. Of course there's a crap load of mods but when it's done it will be a one of a kind. Up to around 450 horsepower the I beam rods are better cheaper and lighter. Generating 500 horsepower from a 350cui engine requires 1. Will the 727 in it be able to hadle the power? Predictably, the small cam makes more horsepower and torque below 3,750, and the bigger cam makes more power after that point. Filling the bores is a really trick set of Diamond custom pistons, featuring a full spherical dish for a compression ratio of 11.
It makes as astounding 610 hp at 6,400 rpm with a massive 584 ft-lb of torque at a reasonable 4,500 rpm. It was all nice stuff. It's a lot taller than the stock intake, though, so be sure to check hood clearance. This pumps the velocity way up with these heads and must be the reason for its incredible power. John at Southeast Performance is just the best for any build. The 360-1 Head for now! The 360 is also easier and a lot cheaper to find. I went to an old Herb Mc Candless article realy old 1999 he used Milodon trays which are some what adjustable.
