I bought the distributor in 2009 and it's the new electronic unit (mallory?).
Engine was assembled on the lose side so the piston to wall clearance shouldnt be an issue.
Exhaust is 2.5in + super turbos, not most free flowing but the intake is close to stock too.
Swapped the box but cant drive the car today - hail and storms here ;|
If there's no change I'll change the jets.

Good advice on timing - didnt know the box moves it
