Thanks, I didn't know that. Was it an AMC pattern or Chevy pattern used on the AMC blocks?
The AMC heads does not bolt up to a mopar engine. Though I didn't think thats what you were meaning.
I guessing 401 heads to 360 AMC engines. I do not see why not though I have noticed that there was a change done to them in the '69 or so year. Edelbrock has 2 intakes for them. (Early and late)
