It’ll be a sad day when I get a newer truck that doesn’t sound like an airplane lol. As for your Malibu I echo others if you can find a motor with a 4l80e you’ll be much much happier. I have a th350 with 3.08 rear gears and 65mph is it’s happy spot. Any faster and It starts to screamOh absolutely! she's tuned and runs amazing! I get so many compliments on this truck its crazy!
