That is your right . Just make sure your torque curve is at 300 when you're at 6000 RPM, and you'll have reached the 340 rwhp goal. The only downside I see is that in return for high peak horsepower, you will probably end up with a combo that actually runs slower. It all depends on what is most important to you .
why wont the stock block like it?
if a forced induction can do it why not all natural with a great set up and tune
alot of trail and error and hopes and dreams the number dont seem to far off I am not asking for 400 rwhp just 340
