Re: Twin turbo 455, FI
Awesome to see another Efi forced induction project. I feel your pain over the machine shop. I got screwed by my machine shop as well. Its tough to get the motivation once you hit a roadblock like that but it's great to see you are getting back into it! Don't add up the costs because you can certainly buy an LS cheaper than building a Buick motor. There is no fun in that though.
