I just got a too good to pass up (crap, what can I sell?) deal on a new in the box TBI fuel injection system and an MSD 6A. So, as much as I like my speed demon 750 it's going back on the shelf.
So I start reading up on this and find out that the only way to let the EFI control the timing is to have a CD spark box and a crank trigger setup ($$$), OR, have a computer controlled HEI. SO, yeah, I could just plug in the MSD and continue to run with the mech/vac settings, but the idea of being able to tweak the timing with a couple keystrokes is just too cool to pass up.
Anyone know if pontiac made a computer controlled HEI distributor before everthing went corporate? I'm guessing maybe the '81 301 turbo TA? Or are there any other tricks to make this happen?
Thanks
Thomas
