440 Block Kits:
440 >> 500. (4.150" stroke/6.760" rod) Approximate Bobweight: 2200-2250
Our original kit, and still one of our best sellers. Includes our Platinum Series 4.15" stroke BRAND NEW FORGED 4340 steel nitrated crankshaft with profiled (rounded) counterweights, and original Chrysler sized standard/standard rod and main journal sizes (2.375" rods and 2.750" mains.) Rods are our super light Platinum Series H beam 6.760 rods with American made ARP 7/16" bolts, and your choice of flat top, dished or Domed premium forged 2618 T-6 US made racing pistons, and full floating .990" pins. With most of the piston choices for this kit weighing in at around the 600 gram range, the bobweight on this kit usually comes out to a very nice 2250 grams or so, depending on piston & rod choice.
This kit is one of the easiest kits to put together, especially if this is your first stroker motor. For a low maintenance, high horsepower setup at home on the street as well as the drags, nothing beats the 440>>500 kit. Slight clearancing of the very bottom of the cylinder walls may be necessary. If you have a die grinder you can do this in your garage with no problem. This kit will almost always clear factory internal 3/8" and 1/2" oil pickups. We supply Clevite's "H" series champhered or narrowed bearings to help clear the larger radius on our cranks. See our
Bearings page for details on bearing fit/function, etc.
Additional Options:
Upgrade to ARP2000 rod bolts: $99 This upgrades the standard ARP8740 bolts (which ARP rates up to 850 horsepower,) to ARP 2000 bolts, which they rate up to 1200 horsepower.
Upgrade to H series main bearings with larger thrust surface (FITS 1974 AND LATER engine blocks only!!) $59
Any flattop or dished Platinum series pistons (listed below) are included in the base price, there are no "extra charges" for dished pistons. We figure the ratios below with a standard .039" head gasket, which is the thickness of Felpro's popular #1009 Chrysler big block head gasket. All our pistons use the lighter and stronger .990" pins and 1/16, 1/16, 3/16 ring grooves. Low tension or standard tension rings can be used. Valve reliefs are generally good for about a .700" lift cam.
