I have a 69' Coupe with a ZZ3 small block and a M-20 4-speed with a 3.70 axle.
Being accustomed to driving big-block vehicles most of my life, I am somewhat disappointed with the level of performance of my ZZ3- Mainly low end torque.
I have recently aquired a 400 CI small block from a 71' Chevrolet (4-bolt main) that I am considering using for the basis for the C3. Tentatively, I am thinking about using the 400 short block (with the low comp dished pistons) and putting on the 58cc aluminum ZZ3 heads to bump compression to around 9.5, along with the ZZ3 aluminum intake/carb.
The questions I have are:
Has anyone done this before and what was the result?
What would be the best cam selection for this combination (I want great low and mid range torque- The motor would never go above 5500 rpm)?
Does GM or anyone else make a 153 tooth flywheel for the 400 small block (externally balanced)?
I just put a new 10.5 clutch in about 300 miles ago and would like to avoid having to convert clutch/bellhousing/starter for the 168 tooth flywheel.
Any tips or advice would be GREATLY apprecited!
Thanks,
Elm
