Time for new engine in 72 Swinger - What Would You Do?

not much diff , compared to the cost of a 400 hp 5.9 motor ( carbed ) and a 5.7 hemi , doesnt take much for the 5.9 to be Superior than a stock 5.7 , even a 6.1 or 6.4 , comparing the cost of new radiator and xv intake , and wiring for the Gen3 hemis ... for less than 2-3 k and you have a 450 hp motor with the 5.9 , for 5 000 $ youre sratching the 500 hp and 500 ft pds of torque easy , and on 87 octane !

ps: im not a huge fan of the 5.7 hemi , but of course they are good engines , but a lot of people forgets about the 5.9s
