hp estimate w2 360
I ran a similar combo.. 12.5:1 custom Venolias , 638 comp roller , Eagle rods , M1 single plane , Totally tubular headers (TTI now..) , Norris Stainless roller rockers , titanium retainers..etc...
Herb McCandless walked me through the build over the phone...( those were the days !)
That motor would hit 7800 so fast !
