Wanting to hit 500hp??? As of right now I have a stock '00 trans am. My thoughts right now is to get all the bolt ons done and rebuild the tranny. I want this car to be very street able so I can drive it everyday.
I am wanting to hit over 500whp N/A but am not sure on how to do that. This will be a on going project so if I need to save up more money I will. What I was thinking was a very healthy 383 or go with a LQ9 408. The 383 would be a lot cheaper to build but I haven't really seen people with a 383 over 500hp. On the other hand I have seen some 408 over 500hp but they have been radical builds that really are not street manor cars.
What do you all think and what do you guys have or seen. Thank you.

You're better off shooting for a specific 1/8 or 1/4 MPH that a dyno number especially with a automatic. No 2 dyno's are the same but all drag strips are either 660 or 1320 feet.

FI has been a thought but I want to try to get there just N/A motor.
I have read through that link about hitting 500hp and that is more extensive than what I can do since I do pretty much everything myself but it has a lot of good tips and pointers.

You can do it with a 383 hell its been done with a 346 a few times , but the more cubes you have the easier it will be for you. Also the bigger the cubes the more the motor will be able to handle the bigger cams and still be easy on the street. Now saying that I will say it will come down to your heads and intake sys. Heads are the hart to the motor . The better the heads the more power you will make . You cant just throw the biggest cam out there in it and not have everything else match it . Get the best heads you can afford on it and have a good intake sys match up for the heads. Then have a custom cam spec out to match the flow # that your heads have and I cant stress how important it is to have the cam spec to match your heads flow #s and were it flows at and at what lift. Just take your time and do your research man there are lots of people in here that can answer just about any ? that you may have . I will say my 383 had afr 205 heads milled down to 59cc and I had a custom cam 23? int and 24? exh. going through kook 1 7/8 headers with high flow cats and borla adj cat back. car was a a4 with a circle D 3600 stall and with the stock 3.23 rear in it and it came close made 489hp and 486 lbs if I remember right. and with the same heads and set up just different cam through my 402 I am well over the 500 hp mark. Like stated above the more cubs the easier it will be to make it and stay street able.

I could of gotten a little more out of it with better exhaust "true duals" and bigger heads afr 225-230 or trick flows just to name a few. Hell I even still had the ls6 intake on the 383 so with the fast intake it self would have gotten there I think now that I look back at it.

Was your 383 streetable??
Thats true about the more cubes thats why I am leaning towards a 408 even more so if i can transfer everything from an LS1 to the LQ9.

It was very streetable . It was and still is my daily driver car. To be honest I liked my 383 more then my new 402. My 383 was a top end pulling **** due to the cam I spec out for it. The 402 is a stump puller makes with in 5 hp and torque of each other lol. Its a great motor and fun as hell on the street power and torque everywhere in the rpm band but some of the power get lost due to spinning and wasting all that torque. Since I am on the stock 10 bolt rear end I do not want to due the correct set up just it as my rear would scream uncle before it snaps lol. My 383 made a lot of torque too but higher in the rpm and my car could make use more of the power it made "able to put more to the ground" . A new rear end is my next mod after I pay off this motor.

I went with the 402 because i didn't want to go with a iron block and put the extra weight on my front end. Plus the 402 "ls2 block" is go for around 800 hp. After all is said and done my car should be a little under that after the rear end up grade and pro charger set up.
