Since the short deck is being used, the compression height needed to be so short that the wrist pin encroached on the oil ring, necessitating the use of a support rail. “This engine is so big, he doesn’t have to shift at 7,000 rpm to get solid power. This particular engine, built by Motorsports Unlimited in Terra Haute, Indiana, is more reminiscent of a bracket racing engine than an almost-unlimited Mud Drag Racing engine. In addition to the drag race baffling, a louvered windage tray is used to control excess oil motion at the full seven-quart capacity. We’ve mentioned a few times that this is a street engine. After thoroughly cleaning and inspecting the Dart Big M block, Petralia measures and records all critical dimensions for blueprinting. With that in mind, the Total Seal AP Steel piston rings were file-fit with a slightly-larger gap as well. The block is then outfitted with King Racing bearings, with the clearances set on the loose side, since the engine will utilize a Melling “Shark Tooth” extra-high-volume oil pump. The 1,000-horsepower mark has always been a definitive high-water mark for a street car. Best of all, the components used to create the FAST™ Complete Fuel System Kits are made of aluminum and stainless steel to ensure years of long, trouble-free service. With the automatic transmission, without his foot to the floor, the engine will probably be shifting mostly at 4,500 rpm,” Petralia says. The team complete the tuning session with the spacer attached and ended up with final power numbers better than the customer was hoping for. $17,950. That’s 96 ends that need deburring. THE FIRST V8 ENGINE OVER 1000 CU. Hanging off the crank are a set of PBM forged 4340 steel H-beam rods, also with Clevite H-series bearings. Into that Merlin IV block, Stillwell dropped a forged 4340 steel PBM crankshaft with a 4.375-inch stroke into the Clevite H-series main bearings. The power curve shows that the engine wasn’t done making power at 6,500. 1,053 horsepower at 7,300 rpm and 834 lb-ft of torque at 5,700 rpm. Starting with a 2-1/4-inch tube at the exhaust port, the runners expand to a 2-3/8-inch tube diameter, before merging into a 4.0-inch collector. “I was a little disappointed we didn’t make 1,000 horsepower with it,” Petralia says. The intake manifold comes CNC port-matched from the manufacturer and is shown here fitted up to the same Fel-Pro 1275 gasket, before Petralia does a full hand-port on the intake. So it was quite surprising all around when an additional 1-inch spacer made significant gains. It’s no secret that LSX engines make big horsepower. While the Moroso billet oil pump weighs less than stock, it does require an 8-inch-deep sump. When Petralia hooked the engine up to Hardcore Horsepower’s in-house engine dyno, he only got partway through his power run before an oil leak put an end to the day’s testing, with the final recorded numbers at 927 horsepower and 829 pound-feet of torque. In the back of the car sits a 6.5 L 65-degree V12 built by Cosworth that produces 1000 horsepower at 10,500 rpm and 740 Nm (545 lb-ft) at 7,000 rpm.

Make sure to stay tuned, as Petralia has promised us first crack at the results from the next Hardcore Horsepower test session. “The engine’s sole purpose is to be a very powerful pump-gas big-block Chevy for the street. It is believed the engine in question is a new V12 built by AMG and developed in collaboration with HWA, the same folks behind the bonkers Apollo Intensa Emozione (IE). The oil pan is a straightforward Moroso steel unit with built-in windage screen, crank scraper on the right side, and trap door baffling around the sump pick-up area. “The increase in popularity of 632s over the past couple of years is due in large part to affordable 4.75-inch stroke cranks coming to market,” Petralia says. Cosworth and Aston Martin have built one hell of a powerplant … Stillwell opted for a World Products Merlin IV block.

In the end, QMP made 535.3 hp and 446.2 lb/ft with a 11.6:1 air/fuel ratio and 35 degrees of timing on our low compression Ross pistons. To maintain timing under all loads, Petralia used a billet roller timing set from SA Gear and PBM. The factory-style gasket is a multi-layer steel (MLS) design that has proven very strong and reliable in naturally aspirated conditions and lower-boost engines of up to about 700 to 750 hp. We will safeguard your e-mail and only send content you request. As technology has improved, the refinement and control of power-adders has progressed to a point where a 1,000-horsepower street car is a relatively attainable goal. While capable of more displacement and horsepower than the goals of this project, being a little overbuilt never hurt anyone. The goal is a 1,000 horsepower pump-gas street motor, and this will be the test mule for a crate engine package.”. Comp Cams 7/16-inch steel pushrods sit atop Erson bushed solid-roller lifters. The revised inlet area reduces the chances of cavitation and the whole setup weighs a pound less than the stock pump and pickup. Controlling those valves are triple-nested Erson valve springs with a 2.100-inch installed height, secured by Erson titanium retainers. “I prefer stainless to aluminum in this application, since I’ve seen aluminum pieces fail when subjected to long-haul street duty when running triple valve springs.”. We promise not to use your email address for anything but exclusive updates from the Power Automedia Network. A 4.0-liter Whipple supercharger adds 17 pounds of boost to coax the engine to produce twice the power of NRE’s naturally aspirated 427.

Aimed heavily at the X275 drag racing class, the headwork with standard BBC pistons and come completely CNC ported right out of the box. The camshaft profile selected is aimed more at naturally-aspirated performance than nitrous use, since 99-percent of the engine’s life will be spent without the aid of nitrous oxide. While an impressive piston, with its large dome, vertical gas ports, and anti-friction skirt material, it’s an off-the-shelf piece from JE Pistons. Fortunately, Canton offers that exact sump depth with drag-race baffling. It does that, and idles at about 1,000 rpm” says Petralia. The trick is having the knowledge to utilize off-the-shelf parts to their fullest. On the right is a heavier tapered-wall pin from one of his bigger nitrous race engines.

An electric water pump frees up some horsepower while a Moroso billet three-vane vacuum pump helps the engine seal up. BRODIX Cylinder Heads Diamond Pistons Trend Performance Products Crower Cams & Equipment Co. EngineLabs Since we were looking for nothing less than 1,000 hp, we decided to take the necessary steps to improve the power of the naturally aspirated 5.3L before adding a pair of boost makers. A naturally aspirated V-8 making nearly 1000 hp without the help of turbos is always a good time. Topping off the stout combination is a Pro-Filer Sniper single-plane intake manifold. In order to do that we have to turn some RPM.”, However, Petralia points out, that it won’t need to be spun to 7,000 rpm on the street to make decent power, as it still has significant grunt under the curve. He purchases his blocks fully machined and clearanced for the big stroke direct from Dart. Topping the combination off is a visually-impressive intake manifold which is CNC port-matched to the intake ports from the manufacturer. The combo actuates Crower stainless steel shaft rockers with a 1.8:1 rocker arm ratio, which if you do some backwards math, gives you an idea of the camshaft specs. Stillwell has a strong relationship with PBM and decided to use the PBM catalog for as many parts as possible in the build. While the brand and runner sizes are kept close to the vest, he will, however, disclose that he has completely worked over the intake and exhaust ports to flow over 425 cfm on the intake and 355 cfm on the exhaust.
