I am having Texas Speed build me a 441. As far as the long stroke being less dependable I wouldnt know, I have been driving an all stroke 395 for 4 years with no problems. I raced a friend of mines twin turbo Cobra out on an open West Texas road and out of 2 runs to 140 he won 1 and I won 1. He made well over 100 rwhp than me and the race he won at 140 mph I was pulling him.

Before you throw money away, you would be much better off selling the car and buying a similar 6 speed car and working with that. Been there done that.

It can be done, but it is far from optimum.

pistons + rods + (used) heads + (t3/t4) turbos/supercharged + fuel (Bosch o44 pump and 60lb injectors) + tune= easy 700 rwp you don't need 1k rwp you can do it with decent heads and a decent turbo/supercharged set up
the supercharged would be better for road racing i think... a more linear power delivery
thers a guy down here making something like 730rwp form a procharged STOCK internals c6 MTI did the car. ask them what hes got, i know its lasted a good while.
maybe you would be happy with ~650!!!
i think his sig is BOLLAS on corvette forum
you might have to wrench some ...its worth it!!!

I thought with boosted applications the A4s are better because you don't have to let off the gas and lose all the boost. You can keep your foot in it and don't loose it all out the wastegate, causeing you to weight for the boost to spool up again.

Keep an eye out on this thread https://ls1tech.com/forums/generation-iv-internal-engine/651346-lg-motorsports-dyno-l92-heads-cam-numbers.html. LG is almost at 500 whp with a stock LS2 short block (364 CI) with the L92/L76 and his cam. Just an FYI as this would be by far the cheaper route to go for your 500 whp goal..
