You either have the car built to take the power or do not , you are asking "if I restrict the rev limit" , absolute nonsense ; just plagiarise somebodies Dyno sheet, tell everybody you have 1500hp ...
Real Street will recommend you to use Billet main caps or any reputable shop, making the power and longevity of your engine under that power , are two different things
You car is 1993 , 26 going on 27 years old, the days of throwing power at these engines with the expectation of longevity is long gone; needs a full refresh, the factory crank pushes down on the caps often leading to stress fractures and cracks.High cylinder pressures will often overcome the strength of the caps and stretch the bolts, causing the main caps to "walk" and actually bounce on the block's mating surfaces, eventually damaging the contact area. This can, in turn, loosen the main bearings in their saddles to the point where the engine loses oil pressure or the bearings spin.
When a main cap fails , you will literally scrap your block, pistons, rods, bearings , crank, most likely some head components for good measure..at 1k hp you are pushing the engine to see when it will fail , not if it will fail
A nice read
