Doug,

If you're going with JE pistons, you can always order a semi-custom set to drop the compression to 9.5-9.8:1 and give yourself some breathing room. I'm not sure I'd go 10:1 with single plug. It may work fine on cooler days or with good 93 octane, but a tank of bad gas and/or a really hot day could introduce detonation. Also keep in mind that you probably have Alusil cylinders meaning you will have to buy Nikasil cylinders or have yours replated.

I have a similar race motor to what you are thinking...

3.0L case with Mahle RSR 10:1 compression pistons
46mm webers with heads matchced and early 39mm/36mm ports
WebCam 120/104 cams
Twin plug, titanium valve keepers, racing springs.
Case windage mod's.

For a nice streetable car, I see two good options: (there are probably many more)

1. Make sure the compression is 9.8:1 or less
2. Use a milder cam than an "S" to make the car less peaky and take advantage of the 3.0L torque
3. Use 40mm Webers for the same reason
4. Upgrade the exhaust to a higher flowing system like a B&B or SSI setup.

This should get you in the 230 HP range.

OR

1. You could keep the CIS and avoid emissions and cold-start issues
2. Upgrade to the 98mm pistons to get more displacement.
3. Use a 964 or Webcam 20/21 cam,
4. Free flowing exhaust. Probably the same horespower.

You can just have your existing cam reground for about $650. You're right about not using a 2.7 or early style cam. Different cam sproket nut configuration anyway.

Plenty of places to recurve the diz. Rennsport for example.

A starting budget:

$3000 for Pistons and Cylinders (purchaing Mahle or JE's with replated cylinders)
$650 cams
$300 diz recurve (guessing)
$1000 exhaust (guessing again)
$250 misc gaskets, etc..
$1500 for webers (if you choose that route)
+25% for fudge factor

So you're looking at $6500-$8000.
