Ok guys I posted on here about a week ago about this guy making custom four barrel TBI units. TBI is a much more affordable way to convert a carburated engind to EFI. The problem with tbi is the stock gm throttle bodies are limited to a maximum of 670 CFM (this being the big block gm TBI units). I have a 400 sm blk that requires a minimum of 750 cfm. I bumped into this guy http://www.customefis.com/index.html on the internet while searching for what I was looking for. He told me he was building custom four-barrel tbi units as a kit for $1500. He finally sent me some pics that i have included here for your opinion. What do you guys think? is the linkage assembly a little cobbled? The good thing is that the ball bearings on the throttle shafts. More about it here http://www.customefis.com/pod.html should I go for it or keep looking?
