I've heard lots of the 318 "Big block" and "wide block" terms growing up. I've really yet to figure out what they were talking about. The only thing I can figure is the 318A engine built up to 1966, which was the poly. I dunno if that's what they were referring to? Myself, I've only ever known the 318LA engines.Ya knowing what I know now.. It was just a 318 sb, but I think at that time my gearhead friend was saying that because of the "look" of the intake.
Wish I still had that car... so much fun was had. When I look back I've owned a lot of 318s .. wish I could say that I've had a 340.
