Engine swap

He should sit down and think about the future. If it’s going to cruises and he wants to be able to say it has a 340 in it he’s good to go. If he’s planning to add horsepower in the near future and has the extra money now build for the future. I think Matt and I broke two 904 converter hubs and knowing their weakness we moved to 727’s. Back then a rebuild on a 727 cost me 275.00 or less.
A 727 does not fit well in an early A. usually there are modifications to the pinch weld at the firewall. He said he wants to run 450 hp, I'd advise a newer stronger 904 in the early A. I also run 727 in everything 67 and newer, except my 4 speed cars which I prefer. I only have one 904 and it came from a 67 Commando car.
