WHAT zo6 you have?..mine is modded and just bearly hits 192 with a tail wind down hill....not shabby but wanna see 210.??..our old bmw m6 did 187 with just the limiter off......??..no experience in a zr1 unfortunately. ...
Anyway, f350 dually hauler for me as well...does 65 on cruise in 6th all day...lol.....it's a lil modded tho...truthfully , my 250 can pull that 17k fairly easily with 3.55 gears..... .with bags,tune,and bd exhaust brake it ain't bad....preferr the dually ANY DAY for that job though...
