360 block limits

Yes, truck motors from the start. That is where I got all my "J" heads from years ago. The best part is, being from a truck, they were not beat up and worked great with the added 2.02 intake valves. They are now getting hard to come buy.

I see them almost daily and from some of the prices I see guys think they are 360-1 Indy heads. I get a good chuckle and move on.
