Curious if this will work on a completely stock dodge 360 that was factory in a 1970 4x4 pickup. I'll be installing that engine into a 1981 Jeep scrambler in the near future. What other accessories/items will be needed to make that engine run with this kit? Or does this kit include everything necessary?

I purchased this system for a 77 olds 403 that I have. I got the adapter plate with part number 3252696 that was required for the existing intake manifold. I've since decided to go with an Edelbrock 2711 Performer Intake Manifold. Can you let me know if I will need a different adapter plate for that manifold?

I have an 84 Ford E350 with a 460. The vehicle also has dual fuel tanks and in tank pumps. Would I need to replace those pumps or could they feed into the single injection pump provided with the master kit?
