looking to do a lq4 swap with a 4l80 in my 92 gmc typhoon need to give salvage vard a vech or vin to find this lq4 in also what truck to get 4l80 from. Thanks for all your help

 

a little search will go a long way with this..but just as a little help 1999+ 2500/3500 Trucks and Vans. i think there is others too.

 

VIN, 8th character, look for U

 

i was told all gmc denali's have lq4 is this true

 

The way to tell the 6.0 motors, they will have aluminum heads, the numbers on them is 317, besides the 99-late 01, which are steel head motors... Yes denalis have the lq4 in them.. Why do you want a 4l80 in such a light truck??? A built 60 will be more then enough, unless you plan to make a *** load of hp

 

In general, the Denali’s ’01 thru the ’07 Classic’s had LQ4’s except the ’05 + Sierra Denali’s that came equipped with the LQ9. Stay away from the ’99/’00 models, as they had the iron heads and long crank. The crank is not that big of an issue as long as you are sure that you are going to use a 4L80, but if you’re not sure, just stay with a newer model. As stated, when looking for a LQ4, just look for “U” in the vin number. If you were to get lucky and find a vehicle with “N” in the vin, you would have a LQ9 on your hands as long as the vehicle has not been molested. But as was also already stated, if you want a LQ4/4L80 combo, it would be the easiest to just look for a 2500/3500 equipped truck and get all of your parts at once, it could save you some headache in chasing small components and insure parts compatibility.
