Not sure I agree with all the comments. Standard hot rod fare was always build the biggest engine you could. Adding 40 cu in equates to 40 HP in a 1 HP per cube. Now a days we are above that.
Likely most aftermarket rods are lighter and more durable than OEM powder metal parts. Pistons are also not in the same ballpark.
Data point: I did engage TSP on their 416 shortblocks and they stated 7500 rpm is no issue.
The torque curve will only go up...HP will certainly not drop...likely just peak at a lower rpm.
Admittedly, blown applications seem to ultimately have other limitations (fueling).
I'd likely go this way if my current LT1 expires.
