Roush vs 427FE vs Keith Craft

[CobraEd]

This was a pretty heated discussion with a lot of it pointed between Brent and me. After all is said and done it was not a subject that is normally discussed even among car guys and can be tough to present and tough to grasp. Having said that, I still hold to my compliments to Brent that I posted a few pages back. 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.

Poor Hercf16. New member with 9 posts with an innocent question about Roush/KC motors. I'm guessing it will be a while before he posts again.

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

Have to give this two thumbs up, best post, thanks for the laugh!

Re the revving thing, I've had two similar engines, one 406 3.80 x 4.125, and a 408, the 406 had a solid roller, the only difference, except for the 52# crank in the 406 and I'm sure a heavier Eagle crank in the 408, guessing closer to 60#. I could tell the difference in revving, the 406 was much quicker, maybe because of the solid roller but wouldn't bet on it.

I've heard the 347's are quick revvers and wouldn't bet a similar 351 against one, they use what, a 43# crank?

Just my experience.

I'm curious to know what CobraEd, Brent and AL427SBF think about this "quick revving" concept. We really haven't broached this subject much around here.

In my next engine, I am going to have a custom crank made out of tungsten or maybe depleted uranium. After all, I don't want it to rev too quickly or high!!!! :-)

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.

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.
