I have wondered how a CJ would respond to a stroke like this.  Looks to be a neat build.  Joe-JDC

That has to be the biggest cam I've ever seen!  2379 degrees of duration!  :D

Greg got the car running and it's doing well.  Here's a link to what a 528 HP iron head FE sounds like at idle.  What a beauty of a car!

Must be a bitch to get started- might need a pony motor of an old CAT to get it spinning fast enough. And I thought the 330/600 was long duration!
