Just like to add that 46 is an easy restore since all major componets are excellent and there. Son is the welder and blackmails me that he will only do it his way. 45 has all the data plates. Was told to put 235 in with S10 5sp tranny and Nova rear end, and to keep original front end. Any opinions. Also told to put dual carbs on 235 and dual exhaust. Why should I not use the 4.3 chev that was for my flat fender jeep?
