my 3.0 is moving to the 'roadster' and I'm building a new engine for the '67 '912' .
here's what I have / where I'm at so far:
- 3.0 case
- 3.2 crank
- I have JE 9.5 95mm pistons but I just picked up these.....

which puts me into a 3.4. I'll do a check on my engine to confirm CR. I may have to shave a little off the crowns to get below a 10:1 CR.
- SC heads with intakes at 36mm
- solex cams
- 40mm weber IDS
- M&K two in one out with headers
( and shhhhhhhhhhhh..... a 100 horse nitrous system
)
that's it so far. I could certainly go bigger ports and a more aggressive cam but I'm all about the torque.
any thoughts much appreciated. Don.
