I would. If I was going to be building a stout Teen. You know there was only 22 cubic inches between the 318 and the 340. What was the 340's secret? Compression,Heads,Cam Profile. Do the same to a teen during a rebuild.
All that and the perfect combination of parts and tuning for the street. Gained the reputation as a giant killer. Done, legend made. 3.91 vs 4.04 = .13 of an inch, I doubt most could tell the difference built to same specs.
