Brownie box... solves both probs lol adds one more
I really couldn't care whether my blazer gets a 5.3 or 6.0. I have an '05 5.3/60 in my C10 and it hauls ass.
My concern is with the trans. Knowing how much taller the 1st gear is on the 4L80 is a concern of mine. I look at the 4L80 because I want something stronger than my 700r4. Do I sacrifice strength in favor of a lower 1st (which gets used all the time crawling). Only reason I don't tow more with my blazer is fear of blowing my transmission, same for driving it like a hotrod. I baby it unless I'm in 1st gear 4L
Or 6L80 and pay out the ass for that setup (plus donor truck)
You can swap a gen 4 to a dbc but you’ll have to run a stand-alone style mgmt
