383 Stroker

Well our new engine is on its way!! hear is my ?'s it will be coming stock with 300-325HP We are going to put new headers, a 4 barrel carb. along with true dual exhuast what else should we do to get this engine in the mid to upper 400HP range. We have to be careful the manufacture told us if we use a turbo, blower or supercharger we lose the 7 yr warrenty. Are their any ideas out there? thanks

Either a "H" or a "X" cross-pipe in your dual exhaust.

Heads/Cam/Intake change - not sure if that will void your warranty?

I don't understand. If you wanted 400 hp, why didn't you order a 400 hp crate motor?

I'm with Tech 100% .....and trying to take a 300-325 hp "stock" engine to the "mid to UPPER 400 level".... sorry I don't get it. You'll have to take this brand new engine with brand new parts, tear it down, get rid of your brand new parts....pistons, rings, cam, not even going to mention the heads cuzz if they are stock smoggers they are out the door also. Then you have to install all the right brand new (expensive) hiperf. parts to reach your goal. (????)

What I'm thinking is this is another case of the unreasonable hp expectations. Here's a suggestion, take it or leave it but remember you asked. Why don't you guys lower your hp goal to 375-400 ....THEN you can probably use all the parts you have except for a cam change and the items you already mentioned. If you don't know you REALLY need to find out some info from the engine builder like piston deck height, type of cyl. heads and combustion chamber cc so you can figure your true compression. Big lumpy cam, big carb to try and gain hp with low compression and small ports = a pig

We original was going to go with a 5.7 350 than we found out for a lil less than a 1k$ we could get a 383 so we went ahead and got it. We were not budgeting ourselves for an engine of that caliper bcz of prices. we were able to get this one for under 2k with a 7yr warrenty. This is why we are trying to see what others have done so we can consider the thoughts and not void our warrenty.

Trying to figure out what you are asking for here is some of the info that came with the engine description. 400 Crank Shaft. 3.75" stroke. 5.7" Rod Length. Camshaft-Elgin E923P, Bore size is a .040" Ove the heads are alluminum full roller rockers and has ported and polished cylinder heads. We afound out we can put a mini Ramair on it and will not void our warrenty. So we are highly considering this add on also. If more info is needed please ask

Well it came with a 194 intake and 150 exhaust. we do not know the exact compression yet. The heads could be changed however my dad is not wanting to change them to alluminum cause of horror stories he heard from others who tried it. I am not sure if our cam is a good cam or not its a new Prostock Elgin made E923P. They said it should be good enough for what we are trying to do with the car.

You think it would be better to go with a cross-pipe and not a individual exhaust? why so?

These types of systems help with low end torque, balance the exhaust, and actually makes it sound better.

Wow... um... This thread might be worse than guys who pick a cam soley on what they thought they heard from a a camaro one night at a car show five years ago....

First off... it sound slike your ehads are probably crap... not crap for a grocery getter, but I would not try to get 400 horses out of them... I would insteaed concentrate on getting it finely tuned and maximizing your torque, and changing the rear gear if you need to.

For a 400 horse 383 about the cheapest heads you can go with are Vortec, yea you can do it with others but not without some great port work or sloppy lown end. Get some good heads and compression around 9.7:1 and go with an Edelbrock RPM intake and a 268 cam- I like Xtreme Energy or Voodoo, but they require good oil and careful break in.... most people settle for something a little milder for those reasons. Run that on the headers and exhaust setup mentioned and you'll have it- but as mentioned that pretty much means if you buy anything more than a solid shortblock then you're wasting your money.

Dont really know were to go with this , you dont want to void the warranty ? while not voiding the warranty what can you change ? Can you post a link to the engine you bought , The may solve some of the riddle . What car is it going in ? it makes a difference if its a heavy 62 caddy or a light 75 vega . What is the end goal ? a dialy driver , weekend cruiser or a drag car ? How important is gas milage ?

Wow!
I think a 3/4 cam would work with that.
