I bought a 86 chevy siverado k10 a few days ago and am unsure of motor size. the guy said had 350 in it but when i ran vin it said truck had 305. i located the engine code and it was v0723ufc, which i ran and found it could be a 305 original from truck or a 350 from an 80 van. alot of the things under the hood have been disconected like someone could have swapped it out. It runs fine but need to know size. does anyone have any ideas short of pulling the heads and measuring pistons?

the only engine with the code ufc is a 1980 350 which was in a van or bus c-30 & 3500 very likely 4 bolt main 165 horse with 4bbl at least this is what my code sheet says, you could pull the pan and see if it is a 4 bolt than that will rule out 305

get some brake clean a mirror and alight and look on the back of the block for the 5.0 or 5.7L stamp
