That's the story - they copied a Cleveland head. If that's the case, which I can't argue for or against, then they never had a 5 main block with 4 bolt caps that were buttressed. And they definitely never made a 1000+whp capable stock block and crank, let alone rod and piston. FWIW, I love the claims of the head copies because I remember so many Ford heads with cathedral ports (wink, wink). I have a friend (hard to believe)/aquaintance that argues this Ford superiority/GM theft argument non-stop..............and it's laughable.
I will be the first to admit that the Coyote and modern Hemi platforms are superior, but until I can find one in a JY for $200 that can whoop me with a cam and set of springs, then I'll rest my case. A coyote and $15-20k can definitely kick my butt, but give me $20k and I'll throw a can whoopass at them like I'm the Water Boy.
p.s. trash talking is fun, hopefully no one gets butt hurt because that's all I'm doin'
