I would say to call Summit racings toll free number because they have a contract to sell gm crate motors and crate motor parts. Like it says most things are not listed in the magazine. Plus judging by the site it seems that it is a new product on the market. But you may want to look into other aftermarket cam, heads, and pistons because that is alot of work on the motor to only gain 22hp and 17ftlbs, unless you have the cast iron block but still look into others before you make and rash desicions. Also I was curious who you went through for your 4.10's?

Check the hp/tq #'s for your truck. My '06 is listed w/ 315hp not 295. 295hp sounds like '03.

i bought them in a 4wd store in tucson az, and i installed them in mexico, a good mechanic did that job for me... everything worked out perfect... plus i rather pay 250 dlls to get them installed than lot more money in the us.. also i put posi on the rear end.. it was a good improvement from 3.42 to 4.10... worth the money...
