Really? 30 inch runners? I knew they were long but that's just way too long. I don't think injector relocation will fix power but it should do wonders for idle, low throttle tuning & throttle response.

Greetings,
As I mentioned before, one of the relatively easy options for improvement will be to move the 4 injectors, and keep the current intake. As they are now, all 4 injectors are in the TB, which is 30 inches away on the cold side of the engine. I believe I can mount the two stock primaries back in the block, and can probably mount the two secondaries in the intake, maybe 2 inches from the engine.
Here's the question, do you think this will increase power? In other words, am I losing power by having the injectors coating the inside of the long tubing, rather than efficiently delivering the fuel to the engine?
Thanks,
Rusty (thinking of draining one fuel tank, and filling it with helium to improve climb)
