The van I’ve been towing w/ for last three years has been replaced w/ a gtm360 trailblazer type SUV it is a midsized w/ 5.3AWD L33 all aluminum engine.it’s called the Saab97xxi5.3 303 horse power 330FT LBs weights 4650LB towes 6500 w/ 600LB
Tongue.weight. this is the finest trailblazer made for nice denial intera 13” rotors on front and rear brakes 18” rims.
I know I a little about the LS1 modding up horse power. I’ve kindof picked out a stroked 6liter 403ci proballey 650HP normalley. w/ a 4L80E. w/ upgraded transfer case & diff.s
I believe the turbo desils have serious torque. Upwards of 900FT LB w/ little tweeks on turboing.
