It seems this subject is coming up more and more. I've about had it with the computer controlled 350's myself. I may be crazy (you kidn't have to agree) but it seems like the computer is trying to counter whatever mods that are made to this engines. I have a 77 FBM 350 with RV cam and other minor mods that I mated to the TBI heads and intake. I've been having a lot of trouble with the idle control increasing to 1200 rpm at idle for no apparent reason. It will do this out of the clear blue and even do it while sitting at a stop light. It's possessed!!!!!!

I wanted to use a 93 350 I have in the crate in my 30 Ford but with all the trouble I've experienced with TBI I'm about ready to buy an old 283 or 327. You can set the timing and leave it, adjust the carbs and leave it and not worry about a computer screwing it up as a result of some unseen minor electrical problem. This kind of stuff takes the fun out of rodding and can drive you nuts.

Overall, from my experience, I think you shouldn't try to make a hybrid motor. Either accept the TBI as is or use the old carbed motors and tune as you go.

What do ya think?
