That's 9 posts in over ten years on this forum.

HAHAHA . . . it was quite a flail! I have seen better organized gorilla $hit fights at the zoo.

He has proven himself over and over on this forum to be not only a top notch engine builder, but also a good man of character and integrity. I still have very high respect for him in spite of the verbal dueling.

And a good time was had by all.

No hard feelings here Ed. Shows character to say what you just said and I appreciate it.

Honestly, I think we were all in agreement, and just had trouble with semantics.

Madmaxx's comment was:

"As far as FE and stroked small block, the small block will rev much much quicker..."

The way I'm understanding that is that it doesn't matter which small block it is, or which big block it is, the small block will always rev much, much quicker. In that case, the 351W in my grandma's '74 LTD would be zippier than John Force's funny car engine.

I think what he should have said was, "In the cars that I've driven, the small block engines revved quicker." And most likely that would have been a true case, because people tend to put 40-45 lb flywheels on the FE's, put numerically low rearend gears in them, build them with heavy cast pistons, let the total timing come in really late, etc.

Al, one last point, eschaider said, "One thing however is for certain, all things being equal, two identical engines, one of which has a lighter rotating assembly, the engine with the lighter rotating assembly will always out accelerate the engine with the heavier rotating assembly — it is inescapable." However, it's entirely possible that the FE could have a lighter rotating assembly.... No hard feelings to you either.

Y'all have a good night. I'm gonna chill with the fam.

OK then, we're all in agreement that an FE is the best engine for a Cobra. I'm glad that's settled.

but how about a replica????

Uhhh, considering that the only Ford parts on my engine block are the rebuilt starter and rebuilt alternator, I think that might qualify it as a "replica FE."

Forum threads that take off on a pissing contest tangent are child's play
to "other" past experiences and about par for the course to other forums
I am a member of, think union issues with a bunch of type as as far as
forum pissing, as for "other", that was just a different life but fun.

Mine has an FORD oem intake and... ford badges (but they are only replica badges )

Does that make it less of replica than yours?

[Varmit]

now back to KC engines vs Roush

Great analysis and discussion by the way

I understand that a lighter reciprocating mass will rev faster, but it doesn't mean it will under load.
Any weed wacker can "rev faster" than my engine. As did the makes of the skirmishes I've had on the freeway, from Ferraris to Lamborghinis to Porsches, et al.
I can't make sense of it. Their engines rev faster than mine, but they end up in my rear view mirror in a matter of a couple seconds.

Apples and oranges comparison, twin paxton 468 FE in a light Kirkham against much heavier euro competition and you can't make sense of it lmao.

[rodneym]

No need to 'lmao'.
My post had a at the end of it. I understand.
I just like to beat my hairy chest like an ape...
...you know, because I drive a big block...........

Seven pages of.....

This thread could qualify as Club Cobra's biggest waste of space in history. And Evan wasn't even involved.

Physics, definition of generalization, Rodney beating his chest and Patrick yapping on about FE's only belong in Cobras, though he didn't use the "kids cry when they see small blocks under Cobra hoods.

And everyone just ignored the post about how BB's handle like pigs on road courses (exaggeration by me).

Anyway, thanks for nothing.

Likewise, thanks for nutt'in

This is all from memory so it may not be absolutely correct but from what I remember when Ford was sponsoring Jackie Stewart in F1 and John Force in funny car we got to see some of their data. Both the F1 Cosworth and the Hemi fuel engine would rev at a rate of 50,000 rpm per second.

[ItBites]

In first gear, my hydraulic roller cammed 540 cid engine revs from 6000 to 7000 rpm in 0.3 sec according to my datalogger. Makes it really important, and almost impossible, to time that shift at 6300 rpm correctly. In fact, I would bet my car, with a bigger big block than most of y'alls, gains revs faster during its 10 sec quarter mile run than most of the small blocks that are owned by participants in this discussion.

I gotta add that this thread has been the most laughable thread in 11 years I have been here. Soooo many assertions of 'fact' and about 'physics' from folks who have no business using either of those terms. Hahaha. Y'all need to listen to Brent and Jerry and Barry, and others in the know a little more and rely less on your antiquated 'generalisms' that you heard from someone in high school and weren't true at the time and certainly are not true now.

Definitely should be nominated for best/worst thread ever.

I know some folks who are literally "rocket scientists" that may have choked on their food reading this thread.

"rocket scientists" are specialists in V8 combustion engine dynamics

stop! stop! I'm laughing so hard I can't breath!
with those last two posts let's wrap this baby up and send it to SNL for immediate airing

What's so wrong or funny with those posts?

They make perfect sense to me

Sorry, but are you inferring that you are?
Either way, you seemingly didn't listen to one anyway...
