    Advice on building a 383 LT1

    Coming into a lot of money for my 21st birthday, and I'd like another F-body. I want to build a 383 Stroker LT1 pushing around 500hp. Any brands, suggestions on parts needed, and any advice would be tremendously appreciated. Thanks, guys.

    Look into a 383 stroker kit from Lunati or someplace like that. Takes out the hassle of mixing-and-matching parts.

    Well I already know to go with a lunati stroker set-up, I was curious about what heads to match, Cam, Intake, go with a carb set up or leave it as it is? I was looking for more info on what anyone here has personally used or recommend. Sorry if I was a little vague.

    theres no need to say i'm sorry. its the internet be as rude as you feel like, i do lol. ok back to your car. what are your goals? et you shooting for or just to beat stock vettes and such? maybe some auto cross in the future or just a street car that will rip a few grills out of other cars? you can spend a small fortune or keep it super cheap with different goals.

    take me for example , i wanted to run 9's in the 1/4, not 9.99 either and keep it a 6 speed with 23 degree heads and a HR cam. so needless to say i have spent a nice amount of money so far. its all in what you want and can afford.

    This will be a 2nd car, more for going to car shows, taking out my girl on friday/saturday nights, and of course still being able to walk over other vehicles. I'll be living in a higher end part of town, full of Lambo's, Ferrari's and Aston Martin's so it will be very important that I can atleast keep up if not emberass cars like that. Hope that clears things up a bit more.

    ok 500 na flywheel with a small shot sound good to you? for a total of 600 or 625 flywheel hp? there are a few sponsers on here that offer good cam and head setups that will gross 500 pretty easy. you can use a compstar bottom end, its better than eagle , little below lunati. it will hold well over 500hp and not kill the piggy bank. also i would stay with fuel injection, easier to get adead on tune that will adjust to changing climates.

    Alright everything has been very helpful thus far. Now, intake manifolds are where I haven't been very successful in my searching. Any ideas and or suggestions would be great. As for the nitrous, I feel it would be a bit too much for what I'm doing and I personally don't believe in it either, but something to keep in mind regardless.

    as far as intakes go you don't many choices. you can go to a typical SBC intake and have it worked over to work on a LT1 with a sheet metal elbow , to allow our TB's to work on it. edelbrock makes a lt1/lt4 intake but it has yet to be proven as being worth a crap. there are guys making over 450rwhp with a ported factory lt1 intake. so i wouldn't do anything but get the factory one ported if you go on the wild side a little.

    A question about suspension. Am I going to need to put alot of money into the suspension to keep this bad boy planted to the ground, or just a few things here and there? Lower control arms, subframes, shocks/springs?

    subframes is a must. i went with hal 12 ways , over kill in some peoples eyes. if it is going to stay on the street and just be for fun, i'd say just work on putting new bushings everywhere.
