efi-diy, I have thought about another option which I'm sure has been done. I have several old multicarb intakes. One is a cool fenton with two old school propane throttle bodies on it that would be easy to put an injector on each where the large propane inlet is....only thing is I'm not sure if that would be quite enough flow(both are one barrels). will have to check the dia when they arrive in container in a couple weeks. Another option is the intake which is currently on the motor wchich an old McGurk 5 carb intake. I coul drunany number of throttle bodies here( for instance off newer motorcycle)....the question being is how would one go about setting up the injection....can it be done progressively with middle openig first( run multiple TPS with progressive?)...or would you need to have all open in parallel and use one TPS? Say you have 3 throttle bodies or 4 or 5...due to the sharing of ports for certain cylinders ther is more flow in the center of teh intake than at the ends....would the center throttle bodies get more flow than teh ends and therefore cause trouble with AF ratio in different cylinders???
