you tell them RodKnock
I think it a male thing. Not hearing the whole sentence, not read all of a post asking a question about a something you just told them "all the details" yep, It's a male thing and I believe we all do it.:LOL: maybe we read to fast or listen to fast?????????? miss a lot of details Dwight |
Sometimes we miss details because we are male/human....and then sometimes we miss details because we are trolls.

Yes, and sometimes we miss little details that need "correcting" ...
"Choosing the stroke has a lot to do with the maximum rpm requirement of the engine. For example, in the Ford family on a Windsor block, I might encourage the use of a 4.000? stroke crankshaft to turn to 7,000 rpm, whereas on the street, I might want to suggest a 4.100? stroke crank to turn to, say, 6,500 or I might even suggest a 4.250? stroke if we’re only going to 6,000 rpm because of the frictional loss concerns." Talk to patrickt if you are still confused about this, he spent a lot of time looking into this with his 428FE ;) . |

The stroke doesn't define on how quickly something can rev. Period. I'm so sick and tired of this being spread around.
If this were the case, then as I mentioned before, the 428 Super Stock guys with offset ground 428 cranks couldn't turn 8000 rpm and make 800 hp....or.....the Mountain Motor Pro Stock class guys couldn't use a 5.500" stroke crank, turn 9000 rpm, and make 1500 hp. Look up Jay Brown's big inch SOHC and tell me how high it revs...4.250, 4.375, 4.500 strokes, turning 8000-9000 rpms. |

So... three reputable engine builders walk into a bar with a potential client.
Who pays?:LOL: |
I can almost promise you that we all agree, it's how you ask the question.
You CAN NOT make generalized statements and offer it as gospel. |

FYI, had you said "IMO" I wouldn't have said anything. . |

Just a correction to Real1's definition of a 427 SO. Late 406's and all 427's have cross bolted main caps for racing durability. The center oiling galley used in all FE engines proved inadequate for racing endurance. So, in 1965 the 427 block was a new casting with the main bearing oil gallery on the side. This gave the mains priority in the oiling system and greatly increased the 427's ruggedness. This side galley casting is the sure identification of a 427 SO. I do believe, however, that some service blocks show this casting but are not drilled and use solid lifters.

The long stroke does not matter and doesn't hinder how an engine revs. It's because you build the entire engine as a package deal. I have built FE's with 4.250" stroke crankshafts that would zip up WAY quicker than your SBF...and I have built 4.250" stroke FE's that were pokey because they were hindered by low compression, heavy rotating assemblies, heavy flywheels, and big clutches. If stroke mattered, then you'd have Pat Musi and Warren Johnson losing races and only being able to turn 6000 because of their 5.500" stroke crankshafts. If stroke mattered, then you wouldn't have 428's turning over 8000 in a Super Stock engine. FWIW, Patrick (and whoever else wants to see another opinion), I texted Barry with this message: "I'm so tired of hearing people say that big stroke engines rev slow." His reply was: "Send them over to Kaase's or Sonny's." I can screenshot the text if necessary. |
There is plenty on the internet about this, anyone can google it and read pages from builders & hobbyists on the subject. I'll go with the overwhelming consensus vs. your contrarian point of view. That alone puts you in the "IMO" category whether you like it or not :)

I'm certainly not worried about where I'm "put".
I, for one, know that the overwhelming consensus is usually a bunch of uneducated guys who see something written on the internet, then want to pass it around on the forums to show how intelligent they are. I'm not using "uneducated" in a derogatory manner. It just means that a lot of guys just don't have the experience or background to be discussing what they discuss. This includes you. I'll go back to engine building. You go back to trolling. |
