'77 kenworth, 8V71 GM, 15 speed overdrive roadranger
This is some video I done back in '04 of my old Kenworth I had BIG plans for, powered by an 318hp, 8V71n GM, with a 15 speed overdrive roadranger, it was a good old truck to drive.
100Kph @2150 rpm in overdrive showed it was low geared, with the close steps of the 15 speed, did a good job getting doing from a standing start
straight piped 12v71 pete going to truck show loaded!
Here's what the 75 pete sounds like with dual 6" straight stacks loaded with the 12v71N. It was soo loud with a load on, driving behind it on the freeway was loud. The guy driving wore ear plugs on the trip. We passed like 4 cops and they didn't bother. It turns 2600 rpms and has N90 injectors in it
