[Gmecm] High CR TBI

[Jared Ryan]

So for grins... how potent should a 350 with a 214/220 @ .050 roller 
cam, Edelbrock 3704 intake and stock exhaust manifolds with TBI be?  
I'm just trying to get into tuning it and it's running too rich and 
with too much spark advance (stinking at idle and pinging at 
part-throttle acceleration) so far, so I haven't found all of its 
potential.  It's in a 1984 Chevy El Camino, about 3500 lbs.
