Help needed assessing mystery motor rebuild.

[ibmiked]

I realize that this will be a shot in the dark, but some of the engine guys here might be able to help me sleuth this out.

I have a '68 aluminum case motor in my car from a Euro 911T that was rebuilt about 10 years ago. I have the receipts, but they aren't specific about certain things and I'm convinced the car makes additional power above the 110hp that Porsche published. I realize a dyno or the previous owner would tell me more, but there are sufficient details that I believe an educated guess could be made. Here's what I know;

Stock the car should have cast iron cylinders and 8.5:1 compression and a Marelli dizzy. Here's what the receipts reveal;

Rebuild occurred in 2002 with an indicated 63,074 miles (could have been 163,000 though).
R&L Timing Chain Covers
Carb kits
30mm chokes
125 main jets
55 idle jets
180 air correction jets
F26 emulsion tubes
chain tensioner update (leads me to believe this was therefore the first rebuild)
Rod bolts
Rod nuts
#8 main bearing
Machine work case:
6 resurface cylinder heads: $240
12 rebuild rocker arms: $240
2 repair cam carriers: $104
6 reconditioned rods: $438
1 R&R case oil galley, plugs, chain box modification, install case squirters: $859
911E distributor w/ 7,100 rpm limiter
MSD 5 ignition
MSD Blaster coil
Plus a lot of little assorted stuff like gaskets, nuts & bolts, etc.

Total rebuild cost in 2002: $9,197.37

Any thoughts on what the previous owner or repair shop was trying to accomplish? Simple straightforward rebuild, or were they going for more power somewhere? I don't see cams or valves anywhere, but I'd swear this motor is stronger than stock.

Thanks for any input,
Mike
