I'm trying to build a 383 stroker from the ground up. Already bought a bunch of parts i'm not gonna use, but what i will be keeping for use is a weiand speed warrior intake and eagle crank assembly. I need help matching together a camshaft and cylinder heads that will be compatible with the use of a twin turbo and also be a good daily driver. Good on mileage as well as not giving up alot of top end or bottom end. Hopefully someone can help me out with this stressful situation

Yep whenever you talk good mileage and 1000 hp it is stressful.. Good luck with the daily driver getting good mileage with that set up...

I've read about it being done before but it can be very expensive with having to get most of the internal parts coated by swain, but a guy pulled off 982 hp with 92 octane, racing fuel would put him right over 1,000. But i'm looking for a slightly cheaper way to do it. This guy was a engineer for a company that makes engine parts so i'm sure it wasn't hard for him to figure out. But i'm looking for advice, not ignorance.

Sounds like you are looking for an old "Callaway Corvette" turbo build. Go find one of these, find out how they built it. That is about the closest I believe you will get to your "goal". ( however I don't believe they ever hit that much power )
One thing, you better be prepared for "slightly cheaper" being a figure that you still cant swallow.

Your first two posts imply that you know absolutely nothing about that which you are trying to talk about. I'd call that the root of the "ignorance". The experts and hobbyists are here to share and to assists those who need assistance, not to do homework for a kid who spent his allowance on a hotrod magazine and learned a few terms. Wipe your nose, read a few real books, save up fifteen grand, then build your twin turbo 383 and come back when you run into an issue in the building of it. Or put forth some effort by clicking the "last page" button here and start reading forward. Either way, smarting off, in your second post ever, to those who know more than you will ever even want to know.......will garner you no respect or credibility here jr.

First off what kind of money are you hoping to do this for?
1000hp for cheap no
Budget build..NO such thing. It will cost what it costs
You are on a site with the best guys worldwide they dont always tell you who they are
Humble yourself sit down listen, read read read.
most the stuff and claims you read off the web are crap or junk stuff tossed together and driven with a prayer ea time they start it they dont scatter parts on the road.
Steep learning curve so sit tight save your money and hang around.

Sorry to bring up a dead topic but I am having an issue.
Im currently building a 383 and not being a motor guy i was just hoping to get some input from everyone.
Heres what ive got: 1969 2dr nova turbo350 (art carr built) stock 10 bolt
engine: 350 4 bolt main 1 piece rear main seal block bored 30 over and micro honedclearenced for 400 crank,durabond cam bearings, eagle crank, clevite 77 rod and main bearings, gm o-rods (resized), hyperuetectic kieth black flat top pistons with 2 valve reliefs, speed pro file to fit rings, pioneer high tsi rod nuts, melling high volume oil pump, stock balancer.
Top end: Edelbrock 5087 alum. Heads as follows-2.08 intake,1.60 exhaust valves, 64cc comb chamber,210cc intake runner,62cc exhaust runner. Cam-speed pro #cs-179r or "l79 cam" specs- .050 dur int.222 ex.222, sae duration int.290 ex.290, cam lift int.298ex.298, valve lift int.447 ex.447, lobe centerline 110 int 118 ex 1:5 ratio roller rockers edelbrock victor jr intake 1 5/8 headers, im thinking a 850 holley?
Like i said im not a motor guy so if anybody sees a problem with this combo please let me know! Any one know what the specs would be? Like comp ratio, hp, torque etc? I need some input!!

I remember using the old l79 cam. Great sound but ancient tech now. Have one of the cam guys spec a new tech cam. It will be night and day. Thanks, Charlie

I have used eagle parts before; not a fan. Budget build, buy a junk yard ls 5.3, boost the hell out of it. When you blow it up buy another one, by then you may have the tune down where your engine will live, then do your build.

A couple of things:
1 Start a new thread, you will get more help over resurectting a 5 year old post.
2 Get a modern cam, at least something like a Lunati Voodoo. I believe UD Harold designed those before he left us. Hydraulic roller would be way better yet. Call a pro.
3 The springs on those heads as built aren't correct for a hydrauluc flat tappet. Of course that cam pro guy will tell you what you need.
4 I personally would use a Rpm air gap dual plane if it's a more street orientated build.
Just my thoughts, Jeff.

OK I am assuming from your post that you will be using a stock 350 GM block for this application? When GM designed the small block Chevy they were concerned with it supporting approx. 400HP you are wanting to more than double the HP the block was designed to support. How long do you want this engine to support 1,000 HP ? stop and think what you are asking your parts to do. no coatings will keep the bores round and the mains straight. A very good aftermarket block should be your first purchase in this project.

In my opinion you don't need a 2.08 valve in such a mild engine and a 4.030 bore. As for reworked GM rods by the time you pay the labor bill and bought new rod bolts you have near bought a better rod with better bolts. A 383 with 64 cc heads will need a fair dish in the piston for pump gas. Not a problem but be careful or you'll end up with more compression than you can deal with. For that size of cam I would go with a performer RPM intake. Not a great cam
