I dont get to build 318s very often so I thought I would post this link to a 2.5 minute youtube playlist showing the 318 I built that ended up in a 68 B-body. The owner was going to put a 440 in it but decided to stick with a 318 so he could keep his exhaust and the rest of his drivetrain etc. I think he underestimated the cost of the full conversion, he had already purchased a 440 core motor and then went with my 318 and sold the 440.

thanks
