450-500 wheel?
^ I agree(also add the best heads money can buy to the last part ),and I also hate these threads lol,numbers are just numbers,I will say that getting close to 500 with even top notch is not gonna be a easy task n/a,its all about building a strong running car,that can hook ,take abuse,that you can enjoy.its not cheap and takes time.I can say try and do it right the first time,mistakes cost money ( ask me how I know this) but good luck with the build ,spend some time talking with a few sponsers TSP,EPS,etc I went threw texas speed and there great to deal with,
He is right on the heads where a given but i didnt even think to add them in the list. A 450hp engine can beat a 500hp engine in the same car if its set up right. Peak numbers tell you very little about how strong your set up is. Look for flater cures and early peak numbers that hold all the way up into the rev range and you will have a strong set up that you can have fun with and still be fast 
research is your friend.

patrick g did it for his trans am, and there is a list of other guys on this forum hitting over 450 rwhp. From what I have read, all though I don't personally have a 450+ rwhp car(yet), a custom ground cam, good set of heads and a fast 90/92/102 set up seems to do the trick. However when you get to those power levels, you need to have a built trans and rear end to go along with the motor so it can get expensive...
also looking at the AFR 205's he used, the new stage 2 5.3 heads and cnc'd ls6 stage 1 heads from tsp flows more cfm's so it might be possible to get even more to the wheel than his build got.

lol, i have a 327 that puts over 500 to the wheels and runs 10.00s through a powerglide. it has ported stock heads from 1968 and a carburator.....
you can't get 500 from a fuel injected 350?? you're doing something wrong.

Thats similar to what I was thinking. I've seen SBC combos with similar Cu.in. make those numbers so I don't know why an LSx cant.
oh man, if I was in 1st grade you just got me GOOOODDDD!!!
lol, actually I do want a cookie. but first, breakfast!!
don't be hurt by something that has nothing to do with you. life will be long and hard with that perspective. i know it's hard in maryland, i just spent 2 years there before I had to move back to Texas. i was unhappy in maryland too. if you come to texas we will welcome you!

500 rwhp is definitely doable on an ls1, it has been done before, now it is not cheap, even with AFR heads you'll have to get them touched as well as an intake porting and the right cam for the combo. Im shooting for about 470-480 rwhp and Tony at AFR told me ill have to get my 205's and the intake worked on in order to hit those digits, so it is not cheap!!!!

On the 327 I'd have to see a dyno and video lol. I think that's what he's calling you out on. It wouldn't be that simple to make a 327 make that kind of power. Thousands of dollars and hours of time of getting everything right. On of my best friends races dirt track and they have a SBC that's a 38x? ci all motor that makes 700+ HP but - it is a dart block, all built bottom end, runs on 114oct , and has a carburetor that's cost $2k by itself. The op on this post is talking about stock bottom end and I severely doubt there is any sbc all motor on 93oct that you can drive pretty reliably everyday that makes close to 500rwhp.

My Z06 has a 408 that puts low 500s rwhp and is streetable. But it's a 408. Man, some people are SO serious!
Here's a couple pics of the 327:
Bowtie block, stock casting heads, all from the 1960's, lol. BTW, it was rated a 265HP from the factory with these heads (valve size is 1.72 intake, lol)
Look us up on Facebook, Blackmon Racing.... We will be at the IHRA Nitro Pro Jam in San Antonio April 1, 2. Stop by and say hello (unless you're in Maryland)!!

Our V4 and ported 5.3l heads would put you in the low 11s on a budget imo assuming decent air and track. My '99 FRC makes ~415rwhp thru 4.10s and has been 11.0@124 on a 218/230 116 cam with ls6 intake and stock MAF in +DA. We have seen the V4 cam make 495rwhp thru 3.90s in a GTO with ported 243s, FAST and our 100mm MAF. Give me a call if I can be of any further assistance. Chris, 817-750-2000
My car dynoed 444.99rwhp and has ran a best of 11.28@119 at the track. If you figure in the power loss difference between a manual and an auto tranny car it should hit your ballpark goals.
