As stated all small block ford engines a windsors. I owned a 62 fairlane with a 221 cu engine and an 81 Thunder Bird with a255 cu. The exception is the 351 Cleveland.
351M(MODIFIED) is the 400 big block with 351 crank. They couldnt keep up with production of the 351W to put in the Torinos etc. so came up with the brain storm to MODIFY the 400 down to 351 cubes and no more shortage.
I don't believe the 302 manifolds will fit in the Maverick with a 351. At least not without some work. Let us know if you do try it. I had a 351W in mine before but it had headers. Not sure what brand they were. I still have them on a shelf, just in case.
Had this discussion with a fellow worker of mine a year or so back, LOL!!!! As a matter of fact Ford only made one series of "BIG BLOCKS" and they were the 385 family (385,429,460 etc...). The 351M/400M and the FE (even though the FEs are normally considered big blocks) family are actually considered "MID BLOCKS". Then all the W family engines are considered small blocks. Then you have the whole "Y BLOCK" thing going on. This should open up some responses........................
LOL. These topics are so controversial. I've always known the 351/400 as a big block. Its what I've always called it as well as all my Ford buddies over the years. Did Ford call it a big block?? Nope its a mid size block. Your right. I'm just so used to calling it a big block its habit. Besides did you ever try to work on one. Compared to our 302's its a big block. Big block, mid block or small block it was heavy under powered, bearing eating boat anchor. I love these engine topics. Always good for a few interesting responses. LOL.
LOL............... yea you are right. But what you have to look at is if it really was a big block........................ Could you bolt the heads on a 302????????????? HHmmmmmmmmmmmmmmmm........
it can be done but u need to make modifications to make them fit the head bolts r different but im not sure what else
Since I'm old enough to be most of your guys father, back in the day the 221, 260, 289, and 302 were just called by their CI, then the 351w came out in late 68 as did the "Boss" 302, then in 69 the 351C and "Boss" 351 came out. We never called the 221.260.289 and non Boss 302 anything other than a Ford SB. The Boss 302 and 351 were just that and the 351w was called the 351w and the 351C was called just that. Since we never thought much of the 351M/400M (actually we thought they were good for boat anchors) they never came up in any Ford conversation. An FE is just that, 390 and up to 460 with the exception of the Boss 429 which again was a Boss motor. To this day if your were at a Nostalgia Drag race and asked a Ford racer about the 351M and 400M I'm pretty sure you would get a blank stare or a "Well, hey kid, those ain't real motors! IMHO
I never hear of a small block 221-302 called a Windsor either until the internet came out. We called the 351 a Windsor, Cleveland or a Modified. I also never heard so many people call a Traction-Loc or Equa-Loc a “Posi” either or a 3-speed transmission called a “3-speed Toploader” until I joined this Form.
I'm with you, when we talked rearends we talked about Detroit Lockers and all the rest were just Posi's. A top loader was a 4spd and 3spds were what your grandfather drove........................(I have nothing against 4drs) and we called 4drs 2...........two many doors............with the exception of the Tijauna Taxi.
i agree with olerodder the 400 is junk but windsors are ok my cousin is upsest with them and bought one come to find out they made roller windsors cuz i knew that after 94 they used roller blocks but his is full roller
Off the subject a little, but the best 351w blocks are from 72 to 76,(not 100% sure of the dates but within a year of these) I think those are the years, as they had the best, heaviest web area. Somehting like 5/10lbs more material in the web area than the early and later blocks. These are the blocks that CHP have used/are using in the high HP short and long blocks.
