Stopsign, this is a pretty easy recipe to get close to 500rwhp. A couple of changes like a custom solid roller cam designed to add about 3-400 rpm to the power band would put you over 500 at the tire easily, and you still would only be spinning the engine 8k rpm to the shift point.

edit: 8k rpm is a lot, but you would conceivably make peak power at around 7100-7200 rpm where a stock production block would survive.

i plan on making well over 500 rwhp on motor with a hydraulic roller cam.
having said that, i believe the impressiveness of a smaller motor is lessened when using a solid roller cam and/or an aftermarket block. (which there are none for an lt1, btw)

Why? Are overhead cammed motors more or less impressive than pushrod motors? Honestly, it all seems a bit ricerish to me. A 12 second 408 fox is just as impressive to me as a 12second 2 liter fox. Most guys don't give a damn about anything other than who wins the race.
BTW, no need for an aftermarket block for 500rwhp from a SBF, even a 302W block. The article I used, while using a solid roller, is using a 302W production block.

Edit: I've seen 498rwhp with a hydraulic roller 347 ford sportsman (a slightly more expensive essentially stock block). 547 rwhp was from a very similar n/a hydraulic roller setup after he switched to an R302 block

A late model production block 302 is not going to live at 500rwhp. The RPMs you would need to get that along with the amount of power would make the main caps walk to the trunk of the car. Sure you could do it, once, twice, or maybe 3 times.

Well, it lived a little longer - about 2 seasons. I made a mistake, it wasn't 547rwhp, that was with an R302. It was 498 rwhp on the sportsman. You're right about the main caps, there was evidence on tear down of the caps walking.
Google "marc arnold" and take the first link that says "marc arnold's cobra" or something similar. As the moderator of the 5.0 forums over on stangnet, I got interested in his story and started emailing him to get some technical information about his setup to help out other members and myself. He's a pretty cool guy. Going mid-9s with a low displacement, hydro-roller SBF is pretty cool.
Another cool accomplishment related to an earlier discussion in this thread, though. He went a 10.92@124 on a 306 stock shortblock build.

Good kill. The guy obviously was talking **** or has no clue what he has.
...so what you're saying is a H/C/I 302 makes a handful more hp then a bolt-on LT1? 
.
I love how LTs somehow got slower and slower over the years, and now they are equal to a 2v.
Once I gave it a 2nd chance after I learned what to do I couldn't believe what a N/A 302 is capable of. very basic H/C/I setup on the 302 gave me 328/337 and 408/444 on a 100 shot. Then 480/506 on 8spi of boost. Opened my eyes pretty quick. 
Maybe I haven't ran into the right LT1 but I've never been left with my jaw on the ground when I ran into a LT1. I get about as suprised as I get when I run a bolt on 2v.

I was posting dyno numbers from my 302 build. I didn't fly cut the pistons so my camshaft was limited. You could build a 302 to make a good bit more than what I made. Sorry but a bolt on LT1 doesn't come close to what a good setup 302 H/C/I can make. Again, we are also comparing 302cid to 350cid.

Just like a H/C/I 302 doesn't come close to what a good H/C/I LT will make.
Not sure why this thread got so riled up, but I'm honestly not surprised

My 5.0L Chevy (Tree oh Five) will destroy all 5.0L Ford (tree oh toos) b/c I am the ****. 
I kid, I kid!
I'm really loving this thread. FWIW, I'm Chevy at heart but I have to give credit where it is due. Properly built engines (in any CID) will obviously out perform a poorly built engine anyday. There are TONS of aftermarket parts out there for all SBC's and SBF's and when assembled correctly it will come down to alot of other things such as who's car performs better and who knows how to drive the car better.

How about comparing it to a Cobra? They were made in the same era and cost the same as a Ws6/SS. No comparison in performance.. Not to mention how much more rare they are.
It has just as much to do with me as it does you and anybody else that is a member of this forum. REALITY CHECK!!!! This is a public forum, anybody can post about anything they want whenever they want. If you don't like it hit "Log out" and never come back again. Quit crying when someone posts and you didn't want them to. You have been a member for 1 year and only 95 posts, shows how much you have contributed to this site. Hell, half your threads are trying to get people helping YOU! Awesome man. You have no right to tell anyone to quit posting or not to post on a certain topic. Get the sand out of it and man up a bit. I love the last sentence... Could we say the same thing about you, why hell yes. You have zero idea who you are talking to while over the internet. Period.
Bad *** over the internet.... You aren't that far away.

Also, I love the last sentence " You have no idea who you are talking to over the internet" I hope you werent talking about yourself LMAO because what the hell are you to me besides some fat *** who sits behind the computer screen and trys to explain to people how great mustangs are. 
You dont pay my bills so I personally dont give a damn about what you say. Maybe you should go work at a ford dealership and sell mustangs. Prolly better than the stay at home dad job you have now. Oh and one final thing Mr. Badass, if cobras are so great then why dont you own one?

Actually tough guy I am currently deployed to Iraq. Im not just playin bad *** over the internet, I am playing BAD *** in REAL LIFE. Something I dont expect you to know anything about. So think about that before you tell someone to "MAN" up. Pretty cute how you have to look me up on here and see what I post about. Wow some life you must have. Just cause im new to LS1 cars I automatically dont know anything about what im talking about..... Right, I get it, so none of the other camaros, trans ams or the corvette I've owned meant anything. Not even when they recieved new motors equipped with heads and cam. They were not LS1 cars. LT1 and L98 and guess what... Yea I smoked Mustangs with those all day long too. I said in my origional post "there are mustangs that I have respect for" just not that many. Its hard to respect them when they are always in the rear view. Also, I love the last sentence " You have no idea who you are talking to over the internet" I hope you werent talking about yourself LMAO because what the hell are you to me besides some fat *** who sits behind the computer screen and trys to explain to people how great mustangs are.

My car runs 9.0 in the 1/8th, big ******* deal, its slow, where did I say it was fast?
All I did is the same thing you did, you said if it was a motor that was setup better, it would stomp him, to which I just raised the bar again.
A LOT of people in this thread currently need a nice week ban, and I honestly believe you might need one as well, every time that I personally see you post you just sit here and stir the pot.
I don't give a **** about your car and who you've beaten, how its set up, or how much more power you can make, just give it a ******* rest.
They lined up and raced, someone lost, get over it.
