1972 350 Distributor Wiring

[mestorod70]

Ive always used an HEI distributor on any chevy engine i wanted power out of.
Upgraded with a better coil and a multiple spark type box.
A stock points type dizzy can be upgraded to electronic...and even use the points to
triger the aftermarket spark box.
That being said...i drill a few holes in my cap to aid air flow and reduce ionization that
WILL happen in hopped up ign systems
Im also a big fan of moroso blue max spiral wound plug wires....build em your self style
If you want the most performance and drivability....im assuming its a small block
Set your mechanical timing....NO VAC...to around 12 -14 initial and have total of 36 to
38 degrees all in by 2800 rpm
your vac advance should be hooked to a full time bellow the carb throtle plates port.
Your total timing with mech and vac advance should be limited to around 50 deg before
TDC.....Get the mechanical advance to make power first.....then modifiy the vac to keep the plugs clean while crusing.....if you get it dialed in...your fast and clean.
