Re: Ford Bronco Ranger XLT 79
 

La verdad no estoy seguro que significa la M, lo que si es que el 351M comparte repuestos con el 400 no se si eso tenga algo que ver con que es BB como dijo AndR3Z.

Re: Ford Bronco Ranger XLT 79
 

Existe un 351 y un 302 BB, el famodo Boss 302 es graaaaaande....

Re: Ford Bronco Ranger XLT 79
 

Hay muchos blocks Ford, pero el 302 (incluido el Boss), 351 y 400 son small block, Big block hay un 332 (el big Block más chico de Ford), 352, 360, 390, etc, etc, pero los mencionados por andr3z anteriormente son todos small block

Re: Ford Bronco Ranger XLT 79
 

The accepted way of labeling a Ford is usually the bellhousing:
429 460 351m 400 all use bells with 11" between the top bolts. That bell is refered to as a big block bell.
The 289 302 351w 351c all use the small block bell, and all of the parts flywheel and back are interchangeable. So I suppose that makes them all small blocks. Really none of these is larger than a 350 SBC, so it is reasonable. Chevy made small blocks up to 400 cubes.

The FE is a totally unique bell, but is unmistakably a big block.

If you really want to mess with some minds:
Remind folks that there is no such engine as 351!
They are ALL 352s, no matter if they are small block, big block, or FE.
In the late sixties when they were developing Windsors, Modifieds, and Clevelands, remember Ford dealers were still doing warranty work on 352 FEs!
They called the newest 352 a '351' to avoid confusion. We now call it 'Windsor'.
Then they made it worse by adding the 352 that we now call a 'Cleveland'.
Shortly thereafter came a tall block 'Cleveland' 352 (and identical 400) that needed a name... They called it 'M', and it had a small block bellhousing for part of the first year. Before the end of the year it went to the Lima big block bell. Ford never made it clear what the 'M' stood for, but folks have made up things over the years... Midland, Modified, Michigan, etc...

Personally, I go against the bellhousing method and just call any 221-351w and all 335 series engines small blocks.
That just leaves FE and 385 series as big blocks.
The only gray area is the 351m/400. It is a very large engine physically, just not in cubes. The others are obvious.

Ahí dice " It is smaller and lighter than a 385-series big block (which is why it was developed in the first place)"

O sea small block (o "smaller" block :lol: )

Re: Ford Bronco Ranger XLT 79
 

no me queda claro pato... pero al ponerlo al lado de un 400 se ve casi igual.. y con un 351W el windosor se ve mas chico .. y a parte la campana del W no aperna en el otro ni en el C ni M.

Re: Ford Bronco Ranger XLT 79
 

segun wikipedia:

:arrow: 1958–1976 FE V8 — big-block
* 1958–1971 Generation I (332/352/360/361/390)
* 1962–1973 Generation II (406/410/427/428)
:arrow: 1958–1981 Super Duty truck engine — big-block (401/477/534)
:arrow: 1962–2000 Windsor V8 — small-block (221/255/260/289/289HP/302/351W/Boss 302)
:arrow: 1965–1968 Ford 427 side oiler
:arrow: 1968–1997 385 V8 — big-block (370/429/460/514)
:arrow: 1970–1982 335/Cleveland V8 — mid-sized (351 Cleveland/400/351M/Boss 351)

o sea, los Cleveland y Modified son MB (no SB ni BB) por eso no calzan las campanas

Re: Ford Bronco Ranger XLT 79
 

como un pequeño aporte
FORD NO CONSTRUYE NI BIG NI SMALL BLOCK
tienen otra forma de diferenciarlos,como por ejemplo la apernadura del cubrevolante.que hay motores chicos medianos y grandes no lo discuto pero no se llaman bb ni sb por lo menos en la marca del ovalo

Re: Ford Bronco Ranger XLT 79
 

excelente aporte don Decano.

entonces está claro q hay 3 medidas, aunq de fabrica no se llaman SB, MB ni BB, en general hacen referencia a estos 3 tamaños por esos nombres.
