Ya know anybody can throw a good carb on and be like everyone else. A true motorhead hotrodder wants to expand the knowledge. And do the hard things that most shy away from. Ive never took a tbi beyond the masses but i have a full roller 300-6 ford with two 650 holleys 10.5 to 1 comp bored over to run 460 slugs that dynoed @425 hp and 790 ft lbs tourque at the wheels in a 79 f-150. So if all youve got is smart ass **** like get a 4 barrel stay quiet.thanks for sharing...

read the post it's a Holley throttle body injection system maybe you could tell me how to set the float bowls and I built my Ford and it's beautiful gasket matched Port polish done all by hand and done all by me trying to be a little bit more positive dude

Wait, tbi for another tbi? I read that wrong. Never mind. If you're using the stock computer, needs a tune.

Thanks, I've been reading up on the ECM and the chips and how to do your own chips in that's I was just wondering who had the best information there seems to be a lot of it a lot of it differs period I'm trying to get more familiar with the ECM fuel injection thing and how to hot rod I don't want to be like everybody else I want to I want to do cool stuff on my own that no one else is done. There seems to be a lot of differing information on it and I'm just trying to acquire a good consensus thank you

Read up on punctuation too, damn. You should only need to change the injector constant in your factory tune for it to run right but if all you have is a stock motor with CAI and headers you're better off with the stock TBI on top.

I've heard a lot of bad things about those Holley throttle bodies. Just with reliability and ability to tune them to run right. Do you know what kind of injectors came in it?
