Henry,

We may not always see eye to eye but I must salute the obvious first class nature of your builds! The motors you and your team put together look to be beyond first class.

Best regards,

PFM

I'm sure this is obvious to others, but why does that case and 4/5 bearing mod only done to that bearing and not all of them?

And, as always, stunning work there Henry - the marriage of art and engineering!

When working with an after market spring all you really need to know is total valve lift and spring pressures. Porsche is notorious for running very low spring pressure to reduce parasitic loss and wear. The point of an after market spring is to reduce valve float at high RPM.
As long as your valve lift is less than Eibach's published pressure @ full lift number and you can live with those numbers, you're good to go.
If you desire higher full lift (over the nose) pressure then calculating spring height becomes an more challenging endeavor.
When we first encountered these springs we were skeptical so we invested time and resources into testing the validity of Eibach's claimed number. At this point we are satisfied that they (Eibach) did their homework.
Of course for all of you "engineer types" that struggle with believing an "old dog" you are more than welcome to do your own homework.

Somebody's gonna get a mighty fine sports car when all this comes together. If possible, ask him to share one he puts that beautiful motor into the SWT!

Of course, that doesn't keep me from dreaming about owning a coupe with an engine like that SS 2.8!!

Although that is a gorgeous engine, I am surprised that given the current state of early 911 prices, that someone would take a number matching engine, and have this done to it. Seems that it would actually devalue the car. Why not take a later engine and do this to it, keeping the original stock? As always, it is the owners choice, but it doesn't really seem there is any value to using the original crankcase in this way.

In any case, if I could afford it, I would put that engine in the middle of my living room as a piece of art.

The "value" of a car is based on the criteria placed on it by the owner. Build what you want and enjoy it. If you're building a car to suit the requirements of some arbitrary standard set by "experts" I think you should "step away from the vehicle". Built it the way you want and drive it. ENJOY.

Henry, With all the mods you did to the case why did you stick with the old IMS rather than update for the bearing one. Measuring the end play on that oldie looks cool though as does the cover.

Henry, instructive thread on a great engine as others have said.

One question if I may. It looks in the early photos as if you've not installed the crankcase wire mesh screens. I assume this is deliberate (or they went in and the photos were just a mock up), and I'd like to know your reasoning for leaving them out. Is this something you do on all your rebuilds?

I have only rebuilt 2 911 engines, both stock, so I am a novice at best, and as a confession I noted the screen absence because I boxed up the last case and then spotted the screens on the bench, so had to reopen, clean, dismantle, fit, rebuild, reseal ...... Oops

Henry,

This is exactly the kind of build that gets me going. What fantastic work. The "stock" DeMan rebuilt motor in my 914/6 "needs" a bump up to 2.8 one of these days.

What are you running for pistons and cylinders? I take it you are using high performance coatings at least on the pistons, anywhere else? How about cams, spec? Still on carbs as well? What hp are you looking at here?

I would love to twin plug mine, but I can't rationalize the cost vs the small increase in performance or am I wrong? It happens.

Lord help me ... here comes that drool again !

Henry, any objective testing/observations done on the increased wear resistance afforded by the dry film coatings for a street engine ?

Henry,
Do you spray a moly coating on the parts? It looks from the rocker photos that I see a freshly bushed/ground rocker and then in the next photo, a dull finish from perhaps a spray coating? I've seen this used on cams to protect lobes during storage/transport/install/initial run-in.

Always enjoy seeing your projects and have learned a great deal from your contributions to the Pelican community. Thank you.

Cheers,
Chet
