Engine
 

I have an early '68 T Engine. It is the Aluminum Case, with counter balanced crank. I am trying to come up with a plan to increase the HP slightly, around the 140 to 160 range? I was thinking of starting with a JE set of 81mm 9.5:1 P&C's. Can I use my T heads, (modifications needed?), and T-Cams (Re-ground?) to achieve a good street running engine? It is going in a '66 911 chassis, so I want something close to the feel of an original '66, with a little more kick. Would these heads work with the JE P&C's, and what kind of Compression ratio would I end up with? Would a new set of Valves, and new set of Cams be required?

I know the Mahle 2.0S P&C's are probably recommended over the JE's, but for street use, what are you gaining with the Mahle option? Are they really needed...........On a budget, but want long term reliability.

Any advise would be most appreciated.

IIRC the T was pretty low hp intentionally. Mild cam and tuning. Bumping compression will not help a whole lot, but a cam change would.

Per Bruce Anderson's book, you might look at a "E" cam profile.

After struggling with p&cs the past year, if you can afford Mahle, buy them.
