1000hp Bbc
1000 hp on that engine should be no problem at 16 psi you just have to have he right turbo's and a cam to match.The real problem in that engine is the piston you will burn a hole in the center of it.It's made to thin i don't know if je fixed this problem yet but when I went professional 11 years ago this is all we did is Twin Turbo marine Big Blocks and Every customer wanted to bolt on a tt set-up or a big roots deal everytime like clock work the piston would burn .Switch two Turbo specific Piston with around .220 thickness the problem would go away.Here's some good advise get a set of Oliver forged rods and a turbo je flat top piston with some hell fire rings.Re valve job the heads with a tight radius cutter and make the 45 .080 wide also when you cut the valve open it up to a 2.25/1.900 back cut the intake 30degrees all the way to the lap line.on the intakes leave the ex's alone.Do a bowl blend just into the valve job but don't go into the radius cut to far clean up around the guide boss on the ex side not much more than that.Inconel ex valves are a must.Cometic would be a for sure .if you have the money do a o-ring reciever groove.Switch the bearings out to h-series clevite has to be clevite.
