I have or will have a brand new 49 chevy which I bought off of here....it has the original 216-4spd. I would like to keep this vehicle as original as possible but would like to drive it every day....I was thinking of just a newer inline chevy 6 cyl and redo springs front and back and add torsion bar to front and maybe add tube shocks that can be removed if I sell and old engine replaced after it is rebuilt......will this allow 70mph on current highways and reasonable handling? Appreciate any help here, my first 49
