I had planned with my wife's approval to turbo her Yukon XL but after a recent trip and some thinking I decided to keep it simple. If a tube blew off with me, no biggie with her and my kids huge problem. So Monday I bought a lq9 and took it to the machine shop yesterday. Keeping in mind midrange and low end is more of a priority what should I do? I was looking at the Thunder Racing Cheatr v.3 219/230. Would that with exhaust and etc be a good setup or should I get worked heads as well? Or a different cam? Thanks

 

if you are looking for reliability I would slap a maggie on there. . .

 

219/230 is too big for a heavy yukon IMO. If you want TQ stick with something like the 216/220.

 

Even with the higher compression and added cubes vs a 5.3? Thunder Racing said it be a good cam.

 

PM Pat G and have him spec you a cam.

 

He's done a couple for me. He suggested similar specs to what I'm thinking of for a 5.3

 

Would heads be worth it and if so which

 

Any opinions on heads? I'm thinking about having a 5 angle valve job, port matching, and milling them to 243 sized chambers
