I am wanting a 350 that will get into the mid 12's. I am also wanting to stay with tbi, if it means going with the aftermarket 4 brl tbi. What would be a good start and some mods to get this going. will be doind suspension upgrades and trans upgrades. Just a little misguided on the engine so for. thanks for help.

 

single plane intake. If the stock TBI with 350 injectors isn't enough then a 670 should be fine.
