As far as LS1's go, there are many options here. If you stay naturally aspirated there is no probelm using the aluminum block. People using power adders usually build an Iron blocked LSx which is what I did for my Firebird. Basically, take an LQ9 block (6.0L iron block) bore it and stroke it, and put your LSx heads, intake, etc all bolt right up.

That was a heavy 3680 lb raceweight too, heavier than most vettes. No power adders either, all motor.

You did notice the smiley at the end didn't you, never hooked up until 3/4 down the track, still ran 121mph @ 13 sec ?

Bone stock tuned motor from the factory. And yeah I do think it is pretty impressive to build a motor in my basement that outperforms the "LS7: The Largest, Most Powerful Small-Block Ever Built" with those high flowing 427ci GM heads, thank you !! And those big bad heads are 15 deg compared to my 23 deg heads make me want to thump my chest even more and you get all twisted when I mention Little Chiefs. Titanium connecting rods and CNC ported heads, mine aren't even ported, hold on for second I gotta go change my shirt.
You can get 1100HP out a set of Little Chief's in a sub 400ci motor, that will eat a big block 496 let alone your big block with all the power adders you need. I think maybe to make things more equal I'll slap on a set of AllPro heads to get closer to the 15deg heads the LS7 has, they should bump up the HP with 420cfm intake and 300cfm exhaust.
We will see who's thumping their chest's when you get your motor together that has to use power adders to make any good times.
And I wasn't even close to 11's it was very high 12's It might run faster with slicks but I doubt it
Mine wasn't built for racing, just putting around town, big difference between building a race engine and cruising engine, I could easily get more power out my motor but drivability would suffer and my 24mpg on the the highway wouldn't be there.

And I'll take my power adder big block that makes over twice the power of a 1100 hp small block any day and do it for cheaper too, and I can drive it across the country, with only a .630 lift cam and 9 to 1 comp, If I wanted to, actually it is planned on doing drag week with it.

That only proves your clueless about getting a car to work on a track. 121 mph is a low 11 second trap, if it hooked you actually will be a bit lower mph because wheel speed is not as high. An efficent 1/4 mile is a bit lower top end mph but very good short times.

Whatever you say your the best you can do a wheel stand, put some street tires on you car and see what happens

I don't recall insulting you and it just shows what kind of person you are. This is my last post to you if you can't carry on a disagreement or argument without resorting to childish insults, just means you have nothing constructive to say. BTW say what you want I don't talk to anyone who has to do that. I would hate to be there when someone stomps on you at race what kind of mature things do you do then ?

I have not directly insulted you, or did any name calling. You just think you were, simply because I am pointing out direct examples of where your wrong. The premise of this thread is a bang for the buck comparison between small blocks and big blocks. your answer to it is to say you spent 15000 bucks in parts alone to achive 460 hp. And I simply state that that is a very poor bang for the buck, through several examples and present other options. I think outsiders would see the constructivness in this debate we are having, and make them do further research, then to take your word for it.
sorry you said your flame suit was on. I guess my flamethrower was a bit too much.

I don't know what you mean by this comment? I explained to you a few months ago about wheelstands. Yes if I had my car set up for a slick and suddenly throw on steel belted radials, it would be a smoke show, but if my class required me to run those tires. you would bet your *** a few weeks of test and tuning, I can be cutting some good 60's on crap tires, not as good as slicks but still respectable. just look at the F.A.S.T. guys. (factory appearing stock tires)

Should I build a 383 or a 400+ motor to get around 400+ for a reasonable price. This is a weekend driver hot rod. Thanks

You should rethink what you said. First I was going to go the LS route and my friend who's been building racing engines for 30 years took me over to a pile of LS blocks that had been destroyed trying to make more power, most put on S/C and they can't take the power. I have a Motown block with all five caps 4 bolt and made of billet steel and the middle three are splayed. The block has the water jackets bigger you can see the bulges next to the cylinders
......
Also shaft RR make the drivetrain so stable I have had to adjust the solid roller rockers in 2 years.
I have over $15,000 in parts alone, I built it in my basement and makes more power than a C6Z06 427 I here are the dyno pulls for mine and 427ci C6Z06 and the drivetrain of the C6 doesn't lose 20% like mine, it's more like 12%. That is one reason they seem to make more power. And mine wasn't tuned, one pull just to see, I had Car Chemestry baffles in the exhaust pipes and they are gone now plus I have bigger headers. I will take it to my buddies shop and have them dyno tune it, no matter what they do it will make allot more power
........................
Way better heads, I guess you haven't seen what AFR had been putting out lately let alone the 400+cfm Little Chiefs or maybe you are not familiar with them.
I took my Vette to a shop that specializes in LS Corvettes, they have some S/C Vette putting out over 1000HP. There were a few people in the shop when I made a dyno pull and after they were asking how much nitrous I was using ( mines just got a carb ). The owner of the shop said and I quote "Looks like the Gen 1 small block is still alive and well"

Fifteen thousand in parts?????? And you still had to spend five bucks on a can of Krylon to keep the block from rusting??? Man.
I spent a bunch less than you, and my engine doesn't need a rest and a massage after just a quarter mile (road course stuff is my thing). Built it in my garage (not many basements in Florida).
Wish I had your kinda money, dude. I could have a bunch more fun in life.

Its nice to take a trip down engine **** lane, however you can get very respectable power out of a 383.
I would say its the budget upgrade of choice when you are keeping the rest of the car pretty much as it is.
The torque needed to make 400 HP under 6000rpm is somehting you will definately feel.
