I did not know that. You learn something new all the time. I may go with a 360 one day if one comes along for the right price. I did have a 360 short block that I let go cheap back in the day. That was early 90s. Back then this stuff was dime a dozen except for 340. Everyone knew what they were. people dont realize that these engines perform well without much modification. They are V8 power, even a 318. You can build them up or run them stock, and they will run good. They make good make Small Block V8 power.
