Cool thread! May I ask, for those of you having done the TBI or EFI swaps here, do you have MPG numbers or track times you could share? I know the TBI gets a lot of flack as factory set, though with a Megasquirt it seems like a nice option for a street car. I'm collecting parts for on a TBI swap for my Scout II's 345 for a few more MPG. I understand the 454 truck TBI's are much larger, flow more and have a more aggressive fuel curve possible vs the more typical 350 TBI's? Which TBI setup are you guys using?
