I agree - Please don't buy those crate motors!! What a rip off!
Build your own, or have a reputable engine builder build it for half the cost....
And be higher performance....
At the time, I had just rebuilt my 318 engine. Then the 360 crate motor comes out and I was a little bummed as the price was reasonable. But I still had to get the car smog checked so I was better off by rebuilding the 318 and running a smog friendly cam and switching carbs for the smog check. I did run most mopar perf. parts as they were not expensive. (pistons, cam, fan, dist. etc...) I got 67k miles on my rebuild so far.
