As of a few weeks ago I was planning on just yanking the 170 and dumping in a 200. After some cost checking I've decided to keep the 170 but switch to a D7 head.
And instead of the Tempo EFI as originally planned I'm looking at going to multiport. (The main reason I was first looking at the Tempo route was the bolt on factor, now that the car is down for a while and I'm doing a head so I figured on multiport.)
What I'm looking at doing is 6 injectors and three throttle bodies. Now, I realize I may be opening a can of worms by wanting three throttle bodies as it's supposedly a "carb method" of thinking and doesn't apply to efi. However to me (and I'll be the first to admit I'm no authority on this issue) it would seem like three smaller throttle bodies spread across the log would distribute the air more evenly to the cylinders as opposed to one larger throtle body centered on the log. More even air distribution coupled with far more even fuel distribution due to each cylinder having its own injector should lead to a better atomization reaching each cylinder resulting in better wet point distribution (IIRC stock setup is around 35% WPD), better WPD means timing doesn't have to be as radical which leads to better reliability, efficiency and power.
So with that in mind, my questions are this:
1) What pound injectors should I use? (right now I'm looking at 19lb injectors for a 5.0 from CJ Pony Parts)
2) What should I use for the throttle bodies? (I'd prefer something from a salvage yard due to cost)
3) This is a shot in the dark, but if I were to get 2 more 1100 carbs, disassemble them, junk stuff such as the float, ball checks, choke assembly, etc and modify/sleeve the venturi so it's just a straight shot for the air could I use the 1100s as the throttle bodies?
