I saw this item at PRI this year and decided to get one. 
The first picture is the original arrangement, which was fine.  The IW unit is pretty sweet though.  Needed a bit of massaging, but all good.

I'm one of the deviants doing a build with Jay's heads and a hydraulic roller, and I agree that it perhaps doesn't make a ton of sense from almost any perspective.  Except for coolness factor.  Honestly though, the motor I built back in 2003 has e-brock heads that were ported to within an inch of their lives by an outfit that doesn't post here...couple that godawful port velocity with a lousy cam choice, and you get a lazy, frustrating engine.  So Jay's heads, and especially his cross-ram intake gave me a great excuse for a do-over. 

I've documented the entire build in pictures which I will post once I have the upper intake.  Jay did revise the lower intake to accommodate the slight but significant intake pushrod angle difference secondary to the higher pushrod cup of hydraulic rollers.  As always, Jay has been incredibly meticulous and responsive in resolving an issue that is unlikely to make up a large portion of his business. 

And it fits perfectly.

I've had a one wire from PA Performance in my Cobra... I've replaced it twice in 8 years for heat related failure.  Cobras tend to have pretty high under hood temps, but that's kinda lame.  Definitely not using that particular unit on my new build.

The topic of thread repair in aluminum has come up multiple times on this site and the other site... This video came out a few days ago on YouTube.  Very interesting and well done. Worth a watch.

This ad came through my email.  Not sure if this is a new(ish) product, but they appear to have a FE part number available...

Thought maybe you guys might be interested.

I think this has come up before, but I can't find it...

Is there a difference in thrust flange thickness and diameter (the part of the bearing that fits into the machined area in the main saddle) when comparing Sealed Power 125M (FE) and 146M (Cleveland)?  And how do those compare to Clevite MS1010HK (Cleveland) in terms of fitment? 

Do certain thrust bearings need to be "massaged" more than others?

Thanks
Phil

I agree with Brent.  I run a single plate clutch in my Cobra behind a 482... The car is so light and traction limited, it's really all you need.
