450 rwhp
See Patrick G post about a similar combo on a Mazda FD RX7, stock LS2 short block with stock LS3 heads milled to 0.03", stock L76 intake and 1 3/4" mid-length headers. He used a 222/230 .597/.600" 114LSA +2 Patrick G custom camshaft ground with EPS lobes. The car made well over 500rwhp and he went 130+ mph 1/4 mile.
