This is a 331 industrial engine. I sort of fell into this by accident. I was given a 241 hemi when a friend died. It was a basket case. Lots of cool old parts. In the time I spent trying to find the parts I needed/ wanted, I realized that some people in the early dodge hemi world are easily threatened when an outsider wants certain parts. Anyway, after searching local craigslist for parts for that engine, I came across this 331. Complete minus intake for $700. I searched the internet for parts for the 331, and quickly learned that the Chrysler hemi is supported by a whole slew of companies. I can get a new roller cam from damn near any cam company. The price and support made it much easier to go this route. Honestly never knew much about these engines, but they are growing on me.
