LOL., that is a funny saying. I am new to all this GMC V-6 Big Blocks but according to Wiki, the only difference between a 305 and a 351 is the bigger bore, improved heads and larger carb. Block is the same as is everything else.
I will try to post some pics of the engine bay but everything is really tight fit in there so I am sure I am sure if came from the factory (in 1957) that way with that engine. I don't know if Western Flyer had access to those engines before GMC released them in their lined but if it was a later down the road add, whoever did that conversion did an outstanding job.
