Oh yea 454 is my favorite motor, but check this out, slobber)

Hhmmmm.... I have a 454 in the '96 'Burb and a 496 in the '05 'Burb

Maybe I should consider a pair of 572's!

What are the HP and torque ratings on the 572?

On edit:

I answered my own question. I see the /720 indicates 720 HP! And I can buy this baby for just under $17k. Yikes!

ZZ572 / 720R Technical Information ·HP: 720 @ 6250 RPM ·Torque: 685 Ft. Lbs. @ 4500 RPM

Yep, I think that would pull my trailer okay. Will the 4L80E transmission and the 3/4 ton rear end with 4:10 and G80 Eaton locking differential hold up?

Like it says a big set of really sticky slicks and I'm sure you will find out fast on that rear end, and tranny!

Ever blown a rear end? Parts everywhere downtown Dav, Ia. Tach said 9,ooo 66 GTO, never did get the wheel hop out of that car. Even after new install! To much fun!
