gen 3 rods I have a gen 3 6.0 that I am putting an LSA supercharger on. It will have a btr stage 3 cam and a 2.5 blower pulley. Car won't be raced but will be a weekend cruiser. Is it really necessary to upgrade to gen 4 rods and pistons for what I am wanting to do?

750rwhp to the wheel in an auto im guessing is somewhere in the ball park of 916hp ( this is on one of those online calculator, which seems wrong to me but w.e. )
750rwhp to the wheels in an manual shows 864hp to the crank ( now im pretty sure its wrong but i know the two numbers between auto and manual would be different )
so how would i know what the "limit" is?
heres a little question that i have, 750rwhp thats what at the crank? for example, 750rwhp is different from auto to manual to the crank.

i read sumwhere on here a good rule of thumb was 14 degrees of timing for 14 lbs of boost as a safe tune . so 16 lbs of boost would be 12 degrees of timing . an 12 lbs of boost would be 16 degrees of timing . thats the way im gonna tune
Just for clarification as there seems to be some confusion. RWHP = Rear Wheel Horse Power. If the hp rating is at the crank, it is usually referred to as bhp, or brake horsepower. As stated, rwhp will vary based on a lot of considerations such as auto or manual, which auto, and what rear end among others. Some combos are known to suck more power, such as a turbo 400 with a 9" will eat up more hp than a 6spd with a 10 bolt.
it's all in the tune. how good the tune/intercooler work as well as turbine sizeand cam all have an effect on how much timing it will take.. they will all be a little different.
