Re: 1991 V3500 Project Heavy Hauler
Thanks Boss.
Yep it is a 2000 model year Vortec 454. Keeping the sequential multipoint fuel injection, new cam, factory roller lifters, some GM LS1 injectors, Thorley headers and pretty much all stock otherwise. I'm going with a Howell harness and they will put the older style 4l80e plug in it for me.
