Rear end/Front end differential gears can have a pretty good affect on engine braking as well.

Crossed threads are tight threads.
Idk if motorcycle engines count, but my 2005 Yamaha R1 998cc I4 makes 160-180hp (depending who you ask) @ 12,500 rpms, and weighs 175lbs. The downside is a dismal 75 ft/lbs of torque, and your lucky if they're still running at 50k miles.

75 out of a 1L engine is very efficient. It's not like we get anywhere near that out of our RBV engines.

Careful on your RBV...'19+ Rangers get 270hp out of 2.3L or almost 120hp/L.

@Eddo Rogue : 75ft-lbs*12,500rpm/5252 = 178 hp. Your R1 would be past torque peak, so no longer making 75; so, 160 peak hp is a more legit number...

Fair point. I definitely wasn't including the new generation with forced air, direct injection, etc. Whole different animal.

I was surprised to learn that there is a 361 FE; I always thought it was 352...360...390 for FE, then 389, 391 for FT. But there it was in my FE Bible - Foooorrd V8 Performance Guide by Bill Carroll (it's a '58 only engine - that could be why I missed it). Thx @bobbywalter - here I thought I was well versed in my FE from my misspent youth.

Wiki is claiming there is a 396, too - basically 427 bore/361 crank.
That feels more like the 447; an aftermarket cobbling of 427 bore/428 crank using either custom rods/pistons or both.​
I'm putting the 335 into that category too: 332 with 0.050" oversize piston's from a 360.​
Fun fact - low compression 390 pistons in '70s were actually 410 pistons. And right at end of 70s, you could buy the cross bolt caps from Ford Parts for nominal cost (low enough that high school student could afford them for his build - block was being line bored anyway). As neighbour's farm had mill, spot facing the block and drilling holes required was just couple hours work - oh to be young and strong enough to be able to flip a block around on the mill table. On other hand, 428 pistons were stupid expensive even then, but as sodium filled exhaust valves were used in FT engines, they were quite reasonable. And if the FE crowd thinks a 390 is hot, they should try a 410.

Was the 462 a FE? Or MEL? I know there were both a 410 MEL and 410 FE.

There was also a 330 FT.

Yes, 330 FT is the truck equivalent to the 332, knew about that one.
For me, if it had a forged steel crank, it was a FT, if it had a cast iron one it was a FE with exception of 427 which was a FE with steel crank.​

383/410/430/462 are the MEL engines.

239/256/272/292/312 are the Y block; Have the Offenhauser catalog for the 6 - 2 bbl intake manifold for the 272/292/312 engines. (I was putting Holley 390 on the 2.3 in my Bobcat wagon and Offy had an intake. Aside: If you fill secondary bowl of the bowl of the 390 with pop (Nitromethane) your Pinto engine produces some serious power for short term (say 1/4 mi at a time).

401/477/534 are the original SuperDuty engines.

Found this video. I’m sure I could do more reading about it… but haven’t. He got 250hp out of a N/A Lima. Granted he built about every part himself. Wonder if any parts a interchangeable.

The 534 always has interested me. Ive never seen or driven one, but i bet those things have mammonth torque. Much better then the numbers suggest.

To bad theres no real build options for them.
