Recipe for 800+ Motor
#11
4.6 bore 4.5 stroke, Big M block with splayed mains(just in case you upgrade HP later). I had good luck with the callies and Oliver's as well. Most of the head companies have a good CNC version head, I like the brodix 3X CNC, I ran a crane hydrolic with .630 lift.I think. This should be a very user friendly package and have a long life.
Good Luck

mounting locations are different on alot of the items. That's one reason I stayed with a gen 6 block. (since I changed EVERYTHING else during the build)

598", 622", or 632" NA will easily get you 800hp on pump gas. Go with Dart 355 CNC heads, single plane with 1250 Dominator and large hydralic roller or relatively small solid roller depending on what rpm you plan to turn and if you want closer to 900hp. 598" is a great motor without all of the clearancing requed for the 4.75" stroker of the larger engines.
If you go blown you can easily get 800hp from 509" motor with stock Iron heads, hydralic roller, 8-71 blower turning slow...a chiller is not even necessary. better heads...more power and even safer....it all comes down to if you want to utilize some of what you have, or start completely over....
