I can't agree more.
I have been all through this engine.
Timing
Initial 15
mechanical 18
All in at about 3000 rpm
It is using manifold vacuum
New HEI, no different on points dist built for engine
735 HR Slayer quikfuel carb
all cylinders are right at 160psi
And the speedometer is correct
Any thoughts would be appreciated.
