Thank you all for the hours I've spent reading everyone's experience and expertise on this forum. I haven't posted much but feel I need some help with an engine swap/rebuild. I bought a 2010 Hoe with the LMG engine w/100k miles on it about 4 years ago. It's got 165k now. I recently Bought a boat(5,000LB) and had to trailer it from NC to MD. Trailering home, my truck never got out of 4th gear on I-95 and at best, I got 8mpg. Needless to say, she's lost a lot of power. I'm thinking of having the engine replaced. I have the knowledge and tools to do it myself but don't have the space or time. I'm either going to buy a rebuilt LMG short block and get a Texas Speed head/cam package. With AFM/VVT delete and new torque converter, that will run me about $5k (+labor to install). I just saw this Summit LM7 crate engine(450hp) completely assembled for $3700. Anyone know if this will swap out for my LMG? Any differences that I'll have to account for? Apologies if this has been addressed elsewhere. I didn't find anything. Thanks in advance.
