Could a 6.6 be adapted to use 6.5 IP and injection system? Since the 6.2/6.5 blocks are so well made.... If a 6.6 can be cooled and handle more boost, by running simple 6.5 injection stuff on a 6.6 you would have durability and simplicity. Plus by the time you buy a used 6.5 or parts to build a 6.5 you could pickup a 6.6 long block for about the same price. Just a thought...... What do you guys think?
