checking the vin can only tell you what it came with... the 305 and the 350 engine look the same from the outside, only way to tell them apart is from the casting number on the top back driver side corner of the engine block, as i have switched 305's for 350's and vice versa.. The 350's will pull quite well, the big thing is the rear end ratio, speed verse torque..
