^Yeah GM is still sucking wind in the gas HD truck engines, even with the new 6.6. Maybe they'll be under rated, hopefully.
As to old engines, what about 351M Ford big blocks, 360 GM truck motors and old 360 Chrysler big blocks.
LS7 is a really big small block too.....

Ford had two 351 engines a Windsor and a Cleveland one a small block the other a big block. Wasn't the original GM big block a 348 porcupine?

I thought both the W and C engines were small blocks and the M was a big block, but I don't know Fords very well. I do know parts aren't interchangeable worth a cr@p between an old 302 and a 351 though.
Ha, didn't know the 348 was the predecessor to the 409. Makes sense as the 348 was the big engine before the 409.
Learn something new every day!

The 351 Windsor is basically the same block as a 302 with a taller deck. The 351 heads will fit on the 221, 260, 289 and 302 but the compression will be low unless you make other changes. The intake and rotating assembly won't interchange without modifications. The 351 Cleveland is a 335 series engine and it's physically larger than the 351 Windsor. Don't know if it would be considered a big block or not but I doubt it. The 385 series (429, 460) was considered a big block. The Boss 302 was a hybrid. It had the Windsor style block with Cleveland heads. There were some modifications made to make it work.

The original Ford (FE-Ford Edsel) big block started out with a 332 and I think the 352 may have been made the first year too but not sure. They also made a 360, 390, 406, 410, 427 and 428 FE engines. I think there were also some different displacement engines made just for bigger trucks.

They had another big block engine that was only put into Mercury, Edsels and Lincolns called the MEL. MEL stood for Mercury, Edsel and Lincoln. Not sure about all of the displacements of them but one was a 383.
