I picked up a 318 2bbl 727 combo from an 87 b150 van. Ran good with relatively low miles. Just wondering whats an easy way to get a few more horses out of it without destroying economy. I've never done much work on dodges in this manner, but I've been told in these particular years the 318 has lower compression than the older models. I've also been told it's hard to tell the 318 from the 360. How can I be sure it's actually a 318. I've ran a couple of 360's years ago and they couldn't pass the gas pumps. I'm strictly low budget here so any advice would be appreciated.
