GM HEI computer control

[Don.F.Broadus at ucm.com]

Hello Curtis, fellow Pontiac fan. The only HEI that we can use for Pontiac
EFI is one from a 1980-81  301 engine. Look for the 4 wire connector , pull
the rotor off and as Bruce said there won't be any advance weights or vacuum
canister. I plan to EFI a 1973 350 Pontiac using a 2BBL intake modified for
TBI.

		The oem EFI type distributors have no mechanical, or vac
advance.  There are some aftermarket efi types that are fuel control only.

		I upgraded my 66 Bonny to HEI a few years back.  It's
non-comp controlled, like from a 77 or so.  Is the only difference between
this and a comp control the ignition module?  Is the vacuum advance
different, or is it mechanical advance only?  I need to know when I go to
EFI.
		 
		Thanks,
