Hi All, I am planning to put a period correct 350 in place of my 250 cu in th350, tranny . What are the expected hang-ups that I can expect .
I have a 1970 350 with a th350 out of a 70 impala ,
Any advice is apreciated .
Front springs and shocks. Might want to look at upgrading the rear suspension if it is weak and sagging. Is it a high horsepower deal? If it is, you may want to put some cash in the rear end to keep it alive.
If you are going with a different distributor than points, you should change out the wire to the distributor from the firewall. Easy swap, thread in best of electric.
