Reply to "Looking for the best stroker option"

I quickkly modeled your engine in Dynomation. Unported 4V head flow data predicts 424 HP
at 5500 RPM. Substituting heads with short side radius work (the ones Dave McLain did for
Glen Hartog) and that goes to 466 HP @ 6000 RPM. Those numbers assume efficient mufflers.
What mufflers are you running? We've shown on the dyno that stock Pantera and Euro GTS
mufflers cost 50 HP on a 400 HP engine. A stroker kit will bring up the torque and feel
much stronger but have little effect on the peak power unless other changes (most importantly
the cam timing) are made.
