Enough to shatter a production block.

Hopefully you are planning on a Dart or SVO block with a strong crank,rods and pistons.
With out the blower I would say it is capable of making 375-450h.p to be safe. (@flywheel)
With the blower (8-10 psi w/o intercooler) over, 550h.p@ flywheel maybe more. Depends on WAY TO MUCH STUFF without sounding stupid.
Hope this helps
P.S
To get 9.3 to one compression with the 205 heads I believe you will have to run dish pistons.
