New Ford 7.3 V8
I see people calling this a “big block” engine. Is it part of a series of engines of different displacements based on a common “big” block?

- I think Ford picked the 7.3 liter displacement to capitalize on the reputation of the old 7.3 Diesel. It sounds like it's built very stout and should preform well. Will be interesting to see what it does in the real world for mpg and performance. My 19 year old V-10 manual transmission is still going strong after 200k miles. I just took it on a 800 mile trip last weekend (solo) and averaged 13.75 mpg.

Tuners never get grease on their hands? Really? Guess all that stuff I got on my hands when I replaced my turbo/manifold for performance turbo and manifold, removed my EGR/DPF/SCR, installed turbo back exhaust, installed head studs, and so on was not actually grease?
Tuning doesn't create horsepower. Hard parts still do. Tuning only unleashes it.
That is really good stuff. These dolts building and tuning 800 plus hp daily drivers just don't know how to work on engines. Just try and imagine 800 hp 40 years ago and tell me that wouldn’t be an absolute handful to drive much less taking it to work every day.

As usual, some respond without reading,/comprehending my entire post.
HINT: I said MOST!!
I stand by that statement.
If it doesn't apply to you..... Don't get your panties in a bunch.
BTW..... 797 HP is available stock. No need to even tune it.colliehauler wrote:

^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.....
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.

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.
I remember GM had a V-6 made out of a big block motor in the GMC trucks mid sixties vintage, don't remember the displacement.
I also remember mid seventies when Dodge put a non turbo Diesel Mitsubishi in a pickup long before the Cummins.
Yeah I definitely wouldn't consider a Cleveland a small block but the reason that I wouldn't think it would be considered a big block is because the 429 came out at the same time or about the same time and it was bigger than the Cleveland. Might be a tweener. ;)
I'm really anxious to see what the 7.3 can do in real world tests. I think I'd like to have one if they'll do what I think they will but if I ever do it won't be anytime soon.ShinerBock wrote:

Pretty tough to beat the reliability of the GM LS engines, though......I'm pretty impressed with how smooth the 5.3L is in my old 2001 Yukon. :BHuntindog wrote:

Tuning doesn't create horsepower. Hard parts still do. Tuning only unleashes it.- I miss the old days. They were IMO, what hot rodding was all about. The Chevy SB had so many possible configurations that one could swap things aroung and build a motor such as the 383... A motor that chevy never produced.
