But yet, look at how many recommend a 360 and like the Teen came with 2 barrel carbs. The 360's were a workhorse engine like the 318. Not meant to be a performance engine. They got modified because of their Cu In. size.
360 did come with some of the 340 goodies, but took a lot of time before it became the preferred starting place, 340 were the go to for the longest time.
Look at people with a 273 some give it a pass compared to a 318 cause it has a performance version.
