Well Yun, the mystery is solved. Great write up on the head gasket, sorry I missed you guys at the shop. No more stock radiators for your...Huh? Keep the write ups coming....I'm right behind you.

I had the Pete Intake cam w stock exhaust combo on my 5.7L. Very nice and smooth. After going w the exhaust cam it made things a bit more raucous but added another ~ 20rwhp. BTW, I did the calibration for my config as well as GC's 380.

My engine has the following additional mods.

-37.5 mm inlet ports
-Headers
-2.75 Inch PowerEffects exhaust System
-catalytic converters
-SGC base chip (thank you Aaron)

With 800 miles on the clock and without a final adjusted chip I went on a dyno and it pulled about 560 HP at the crank. Here in Europe we measure always the power at the crank, unfortunately.
The car has stock gears and is as fast as a C6 Z06. The weight of my ZR-1 is 3'530 lbs

With a adjusted chip and better modified secondaries there is still space for some additional HP's

Hello Frank

The engine has a 12.5 : 1 compression ratio and run with stock head gaskets.
As mentionned it has catalytic converters installed.
You can feel the acceleration difference if it run with or without cats.

Here a Youtube Video of a friend of mine who run his 350 cui Callaway LT5 at night on a german Highway.

https://www.youtube.com/watch?v=VaB0...ature=youtu.be

316 km/h is like 198 mph and the car was not at its speed limit. I love the german highways because there our biests can show what they really can.

Mobil 1, at least, since I bought this car in 2000. I think I was using 10-40 when I lived in Florida ('till August 2001) and switched to 10-30 when I moved back to VA. Similar wear on the rod bearings also.
