How to identify ford 427 Many 427s can be identified by the combination of the 6 screw-in brass plugs on the engine block sides and just below them is the crossbolts for the mains. So how do you tell if it is a side or top oiler from here??. The blocks are interchangeable. Look for a number on the crankshaft. The 352/390/410/427/428 all make up the "FE" (Ford/Edsel) engine family. The 406 also had cross-bolted mains, but didn't have the screw-in brass plugs, unless further maching was done to install them after the fact. I have the plug and the three plugs and hump along the left side so I After doing a little research and looking at pics I have confirmed that these blocks both have the side oil galleys on the left hand side of the block. It appears to have a steel crankshaft rather than a cast one and also looks like it was balanced. There’s been some discussion on another forum that what should be a 3 in the casting number looks like an 8. No way to tell if it is actually the original.

Many 427s can be identified by the combination of the 6 screw-in brass plugs on the engine block sides and just below them is the crossbolts for the mains. The 427 is real expensive, but puts out the most HP. Whether you’re building a mild 332 for a vintage Ford restoration or erecting a stump puller of a 460, it’s important to know the difference between a good block and a bad one. Because Ford has long been infamous for engineering changes, you can count on a plethora of block castings in a single model year. You can be assured the person selling the 2-bolt 427 block is actually selling a 352 or 360/390 block with phantom 427 features, not a real 427. There is also the 3 small plugs with the hex heads screwed into the side of the block at the bottom of the oil galleys. In our discussion we'd like to examine the various visual cues that you can use to indentify the different classic Ford V-8 engines from the Ford Total Performance years. I am leaning toward a 429. It will not have any performance features other than: 1) If it's a 1964 block it'll have the undrilled crossbolt nubs. This is for the 4 bolt main, and only a 427 has them. One way to know if its a 427, is on the lower part of the block, should be 3 bolt head, Per side, that are along the lower edge, Simply take a pics of it and post, if there the right one, you have a 427. Here's the easiest way to tell if it's a side oiler The arrow is pointing at a pipe plug. And it comes in 3 versions, low rise, mediun riser, high riser. It looks like a 385 series which means it may be either a 429 or a 460. The engines we'd like Appears to be the correct 427 block with the HP casting. This is a new old stock 427 side-oiler.

Oh and the Single overhead cammer.
