    pages 16 and 17 of that link are what you want. I should say 16 or 17. Thats the pages of the manual I used to fire it up on a 70s HEI setup.

    awesome, thanks guys. that was the page i was trying to get, but it wouldnt load up. hey sled dog,it says you need two wiring harnesses, PN 8860 and 8861 to hook up to HEI. did you have to buy these? or they come with the box.

    really don't know, dad bought his 6AL as a kit from Summit. It was the 6AL box, Blaster 2 coil, and the HEI cap conversion to get rid of the factory coil. Everything I needed to do the install was there excpet for some lengths of wire to hook up power and all.
