1994 Yukon engine swap

[Greg Miller]

First time user. Glad you guys are here. I need to replace my 1994 Yukon
5.7l engine and would like to increase the horsepower. Entertaining the idea of swapping to a 7.4l. I have not done any measuring, but my gut feel is that it should fit. Any opinions or comments. Thank you in advance for any replies

Have you done any other research? You will need to do numerous other upgrades as well to make that a reliable swap. What makes you want to go up to a 7.4?
