550 rwhp possible?
Go to advanced search, go over to find post by user, Tony Mamo @ AFR, search in titles only for "383". Im sure you will find it, and some other info you should probably read.

I would venture to say it's going to take some 7-10k to reach your power goals.
Stroker bottom end 2k
Killer heads 3k
valvetrain/cam 1k (not going to do it with your cam)
intake and fuel 2k
You're going to need to beef up your drivetrain to handle the power and rpms, so 10k is most definitely what you will need to spend.

Just for me to do LTH/ORY/Catback, 243 Heads, 224R Cam and all of the proper stuff to go along with it? 3200.
Two things that hit me unexpectedly were new engine mounts and ls6 valley cover. OP, save your money, research while you save your money, then start buying parts. This is a system you're talking about. Everything must work together as a system. View other posts on here and figure out what works and what doesn't. Just because you see some good flowing heads at x-rating, doesn't mean that they actually put that out. So on and so forth. It's a science to get the most horsepower out of your engine when putting new parts in it.
Mine could put down a lot more power, pat G said I could gain 10rwhp just by using a more aggresive lobe. However my cam is specd to be easy on the valvetrain 40-50k between springs) and driven every day, rain sleet, and snow so it had to have good street manners at any given time.
So figure in different more aggresive cam, different lobes, maybe a few tweaks you could be looking at 550-575 -/+

wrong, Tony hit 611 at the crank on his 383 build which equates to prob. just over 550 RWHP, read....

Obviously Mamo's 550 wheel Hp is the exception and not the norm or else alot of 383 guys would have close to the same #s with AFR heads.

was more of a guess at parasitic loss through the drivetrain have no idea what it would be on a C5 vette but would end up somewhere around the 550 mark i'd imagine?

You're telling me there's only a 10% drivetrain loss? Okay.
Protip: I'd do a little more than just "guessing" before you call someone out on being wrong when your assumption has no factual data to back it up and is wrong itself.
Did Tony mention if his dyno runs were NET or GROSS? I doubt he was running these with full accessories on the front.

you stated that build was 550 at the crank which is wrong, clearly
A friend with a forged 402, TSP's "Giant" cam, Kooks 1-7/8 headers, FAST90 ported by Tony Mamo, Patriot heads, T56 and a Moser 9" made 531 to the wheels, corrected for his high Colorado altitude. I'd be very surprised to see a 383 go much farther than that if at all
