Hi. My dad just got a truck with a small block chevy engine in it. we were told it's a 350 4 bolt, but the sticker on the fan shroud says its a 305. also, the pullys and fan look like there off of a 60's sbc so i dont know what it is. the only number i could get was off the deck, behind the alternator. the number is v1029tyx. if anyone can tell me anything about the engine i would appreciate it.
