The 4:11 rear end ratio is not going to help in the speed department no matter if you have a 235 or a 350. The 350 will certainly have more power than the 235. Your going to be working that 350 mighty hard if you want to run 65 down the freeway and your gas mileage will be poor. You might want to find out a price to have it moved, then compare the cost of gas for the trip figuring 7-8 miles to the gallon.(I think that may be wishful thinking) Then figure the cost to do the swap. If it was mine I think I would be looking around for someone to haul it for me.
