That GVW tag usually has the engine data on it.There was no metal tag that I could find. I searched all over. I only found the VIN tag and a GVW tag in the door jam.
Maybe the Spartan 70 is the emblem from the fire equipment body manufacturer rather than ChevyBob,
My 1966 dated big chevy truck parts catalog doesn't show a 70 Series truck, only 50, 60, and 80 Series.
Ok Bob,if that truck indeed has a 401m in it dibs on the intake,double groove pulleys,oil filter housing,if it has a spin on type filter,possibly the whole engine if it isnt stuck.Warning ,this engine weighs 850-900 lbs:eek:Makes your big block seem like a paper weight
