Chevy better up their 6.2 production, when I bought mine in 2/2020 I wanted the 6.2 TrailBoss and at the time in the Chicagoland area with an inventory of 1300 trucks there was only 6 in the area, all High Country. The 6.2 has been hard to come by in the Chevy but not with the GMC. I ended up getting the 5.3 because they had really good rebates at the time and with the uncertainty of the pandemic I didn’t want to take a chance at ordering the 6.2 with less rebates at the time of delivery.
I like what Chevy has done to compete albeit 3 years too late. The 2.7 4 banger has 420 ft lbs of torque now for those interested
