Hi everyone, I just bought a 55.1 farm truck that's seen better days and beginning my learning curve on stovebolts. I'm a semi-retired motorcycle/import car mech. so not totally clueless mechanically but these 6 cyls are a new animal for me. The reason for this post is I could use some advice/knowledge on the proper water pump/fan combo for a 235 I picked up to put in this truck. The engine # comes back to a '57 BelAir with an automatic trans (I'm putting a T5 behind it). I was told that to make it work in this 55.1 truck that it will need a shorter pump. Is this correct and if so what pump should I get ? TIA :-)
