hi guys im new here and i have a 1986 chevy k10 pickup with a stock 305 vin code "h".. i am looking to put a 350 in but there seems to be a ton of different ones by vin codes. what year or vin code is the best for me to use or has the most power. this isnt gonna be a race truck but used to commute to work and back and then plow in the winter.
