Hi guys, I've had this coupe since the late 70's, number 1103053. I've never done a complete restoration before so any advice would be appreciated. About the car:
I replaced the stock carbs and intake manifold with 1800 TISA parts about 5 years ago, and the gearbox with one out of a 2002 about 30 years ago.
I'm having the engine rebuilt and was wondering if oversized pistons will disqualify me from vintage racing. My builder says he could easily get me up to 160 hp with higher compression pistons and some cam grinding, which would be nice. I have Bilsien HDs all around with stiff springs and a thicker anti sway bar in front (also a TISA part), so this car is extremely stiff, almost too stiff for long highway cruising. BTW the excrusiatingly rare Alpina 2000CS uses these TISA parts I'm using.
