Dale and his crew have put a few thousand of these things together, so they'll get you the right gaskets while saving you money. The gasket sets-sourced from Pro Power-are from Fel-Pro. |  The Pro Power Prime One pistons...  The Pro Power Prime One pistons come with valve reliefs for any head you could be using. Our pistons feature a thick deck and a 1,000-plus horsepower rating. |  Our timing-chain set, balancer,...  Our timing-chain set, balancer, and flywheel were again sourced from Pro Power. When you get into the complexities of engine assembly and balancing, it's good if you and your parts supplier are speaking the same language. |
"Franky's kit has a 4.100-inch stroke and 4.030-inch bore-this comes out to 419 cubic inches. On Frank's request, we did a forged kit, which is what we call our 'Racing Kit.' The 419 Racing Stroker Kit is for engines requiring strong components for a racing application. A strong Prime One 4340-forged crankshaft, heavy-duty rods, and power-adder-style pistons make this kit the best choice for high-horsepower or high-revving racing engines. These kits are designed to fit any 351W-based block application. They will support up to 1,200 hp using nitrous, turbochargers, or superchargers. Custom kits can be made to handle more power, so your readers can contact us about their specific needs," Dale said. "Users of these kits would benefit greatly from aftermarket blocks from World Products or Dart, as the components would outlive any stock block. Typically, these kits require a little grinding to fit, due to the larger counterweights and size of the H-beam-style connecting rods. Minor clearancing at the bottom of the cylinders is required to clear the rod journal big ends as they swing around. Each block is different in thicknesses and casting, so make sure you grind in the proper area and the proper amount, giving approximately 0.040-0.080-inch clearance."
Each component of Pro Power's Prime One line of engine components has been expressly designed to offer customers high-end performance and bargain prices. Its Prime One crankshaft offers a 4.100-inch stroke and is precision, non-twist forged from aircraft-quality 4340 steel in high-pressure molds. They are heat-treated, stress relieved, and shot-peened, and they also feature nitride hardening on the journal surfaces for wear resistance. The Prime One H-beam rods (6.200-inch in the application) are shot-peened and stress relieved, X-rayed, sonic-tested, and Magnafluxed to ensure durability. They feature 71/416-inch ARP 8740 capscrew bolts, precision cap-alignment sleeves, bronze bushings for full floating pistons, and are 100 percent CNC-machined to exacting tolerances.
Fortunately, since Franky wants to try his luck with a bottle again, the Prime One pistons are designed for power-adder applications. They are precision CNC-machined on low-silicon forgings, and feature heavy-duty pins, thick skirts, extra-thick decks, as well as dual deep valve reliefs to fit a wide variety of cylinder heads. They feature double Spirolox, pressure-fed pin oiling, are lightweight without sacrificing strength, and they are match balanced plus or minus 1 gram. Additional features include a pressure-relief reservoir between the top and second rings, CNC-diamond-turned skirts for tight clearance, better oil control, and high strength for street and racing engines. The plasma-moly rings are also included with all Pro Power stroker kits and can be sourced from a number of high-quality manufacturers. The rod and main bearings are also critical components to each stroker kit. Pro Power includes these with each of its kits.
 Machine work starts at McQuillen's...  Machine work starts at McQuillen's Racing Engines with machinist Scottie Hamilton surfacing the deck of our production 351 block. This is done to ensure that the deck surface is parallel and square to the crank centerline. |  Next, Scottie begins the process...  Next, Scottie begins the process of honing each cylinder. He installs the block, uses a torque plate to emulate the load of the cylinder heads being bolted down, and uses head bolts for the final step. The honing process continues for each one of the eight cylinders. |  The final procedure for block...  The final procedure for block preparation is to hone the crank journal. This step keeps an exact dimension for the crank's position in the block. This is especially important with an older block to ensure a straight home for the crank. |
