The crate engine went in 31k miles ago, stock air box and intake tube, 2.5" true duals from modified factory y pipe with cats.

When the truck was backing onto the dyno some f body guys were laughing "190hp" was their guess, soon as the first run starts "whoa....thats not a stock Avalanche" First pull starts at 1:40, second pull at 3:30, all 4 of my kids went with me to the shop, now thats gansta.

Makes me excited to see what mine will do as a FBO LS1.

I think I may be scrapping the Stroker idea, I'm still debating.

The dyno owner told me there is more in it, said the fuel tables are a little off. With the 275/65/18 tires I was shocked to hit those numbers.

Really excited to take the rcsb ls1 after the tune and exhaust.
