Peak HP from LA block w/ no problems

Also you an get the stroker kit for under $2500. Pistons will cost the same no matter what stroke they are form, You need to either redo your stock rods or replace them with something better anyway so that wont cost you anymore.

The only thing that will add price is the crank, $300 for a cast or $800 for a forged. I would ask around too and see what people have paid for balancing there 4" cranks. Mallory metal isnt cheap and I hear the cast cranks take more to balance out then the forged so the price difference between the two cranks may be a wash after ballancing.
