The output numbers match the back in the day figures. But it’s getting it done with less compression and cam. What size chambers on those heads?

Brent ,
I know you build to very specific needs. With the HP being less than TQ "to me" more cam would have made more HP and less TQ . Probably not what your customer wanted but I was "thinking".
That is a very strong "street" 427. nice work!

Randy, it was cam-poor for sure. Only 227° @ .050". Heads worked well as that little 227° cam peaked at almost 6000.
