I'm currently building a '71 TR code 455. Short block is complete with a 0.030 overbore, other than that I'm keeping as close to stock as possible. Heads are now in progress. The carb. is on my bench & I'm getting ready to rebuild it. The engine was originally in a big car...LeSabre/Centurion/Electra. What I'm looking for #1 is a smooth quiet idle & reliability. I drive on the street only & don't tend to light the tires up. Every now & then I might start rather quickly from a red light with the 350 now in the car. Plenty of power there for my needs. Will the existing jets & rods be fine or should I change to something else.
