![]() ![]() The 351W is part of the Windsor V8 engine family, an informal name given to the engines produced out of the Windsor, Ontario manufacturing plant. It is one of Ford’s longest running and most successful engines to date. New bearings twice (Speed pro 3/4 130m1x. The 351 Windsor is a 5.8L small-block V8 engine produced by Ford from 1968 until 1997. Pretty much looking for stock hp, torque, and the rest of that mumbo jumbo so I can decide what sorta stroker to build out of it. What could this be? Could it be hydraulic roller lifters bleeding off pressure somehow? F4te block Anyone out there have the specs for the 1986 351W Mine is in an F-250 XLT Lariat extended cab w/8foot bed, in case that helps any. Started it up, and had 60psi cold, 22 hot idle, and wont go above 42 psi at 2000-5000. These specs are for stock-type bolts with light engine oil applied to the. Use of crank with longer stroke and stock rods results in stock piston being. Primed it for a half hour and notice oil shooting 4 feet out of the rockers when the lifters would pump up. So I figured maybe I just had a defective pump and put the motor back in. ![]() Ford Australia continued to make remnant stock. All galley plugs are threaded in and sealed. During the 1969 Model year, Ford of Australia imported approximately 17,000 302 Windsor and 351 Windsor V8s. While I was at it, I put a new canton pickup tube that works with my moroso oil pan. I also got another m83hv oil pump to put in. Full street trim, driven to the track, '82GT with 9.5 to 1 compression, 408W 10.77 at 123. ![]() So I pulled the motor again, put new bearings in, including cam bearings. I am using such pistons with a Ford A351 cam, but it is much smaller than the one you described. I primed the engine, had it running 50psi at cold startup, but after it would reach operating temps, it would go down to 15psi idle, and wouldnt reach above 35psi from 2000-5000 rpm (checked and verified with electric and mechanical gauge) Okay, so maybe I screwed something up. I replaced the high volume oil pump as well, but I reused the hydraulic lifters and cam bearings to save some money. It is now a 395, with forged rods, pistons, and cast steel crank. I rebuilt the motor this past winter after having it machined. I bought a 95 mustang with a 351w swap done to it already. While I'm doing that, the pressure gauge will read 0 psi becuase I've removed the restriction of the carburetor from the system.Alright, so this is my first post, but I definitely need help. I can fill a 5 gallon can full of gas in about 2 1/2 minutes with the volume my system puts out. Now your floats drop, opening the fuel inlet valves wider and guess what? You've removed some of the restriction in the fuel system and the pressure drops! As long as you can maintain the VOLUME to keep sufficient fuel in the bowls, PRESSURE doesn't matter. The Ford 351 Windsor was the go-to engine for reliable performance and makes a great starting point for a vintage truck build today. When you go to WOT in a carb'ed vehicle, the level in the float bowls starts to drop. psi 80 GHP JZ7.95 Si R8ce Produces 8 psi 80 GHP S2US ELECTRICAL Street. Here, with the Coast High Performance kit from Trans Am Racing, we have a full 1/2-inch of additional stroke. As a 351W, this engine had 3.50-inches of stroke. Pressure is simply the measurement of restriction in the system. Before we lay the heads on this block, we want you to see what a difference 4.000-inches of stroke makes. You are putting some bad info out there- pressure and volume are two different animals. So if your gauge is dropping you have an issue. In efi cars I know that a vehicle can loose as much as 50% of it's fuel volume and still show pressure within 2psi of spec. The reason for running high compression, particularly in hi RPM engines is to compensate for the drop in actual compression, due to the shortness of time for cylinder filling. If it does you are running out of volume. Having the wrong power valve, could be causing your mixture to run too rich as well, as it could be opening with too little vacuum. Your fuel pressure should NEVER drop during a run. ![]()
