Problems with stroking ls1 to 383?
I have a 2000 c5. I want to stroke the motor. I am not changing heads or cam. It will have the stock intake, injectors and throttle body. Will I run into any driveabilty issues. I drive this car daily. Thanks for any info.

u really need to get a cam with alittle more profile than stock, WHY would you do a stroker kit and not add a 200-400 dollar cam in the mix to bring actuall durration and lift up to what that 383 will need, the heads would be a big plus as well but I can see you will really want to put a cam in and get some tunning, Chime in guys, im wanting to stroke the biotch soon and like info.

If it were me I would be looking at a stroked LS2 402 short block. Rather than a stroked 382 LS1 block.

I think you're going to gain very little hp if you don't change the cam, headers, or anything else.
Normal stroker problems are excess oil consumption. Plus they tend to blow up more easily with FI (turbos).

I would save your money if you are not going to change your heads and cam... Why go through the expense if it isn't going to be done the way it should be. Save your money and do it when you can...

For the cost of a stroker you could do a head/cam package and get more power. It makes no sense to increase the cubes without head work and a better cam. I have heard of no oil use problems with a properly built stroker package.

When modifying your motor the most important question is what are you going to do with it? Once you know what you are doing with it the answer will be much easier. Very few significant mods can be done in isolation. Instead of doing a complete rebuild to stroke the engine and basically get no gain at all, why not just do a cam only or NOS? Otherwise, moving up, heads and cam would be a better choice or a supercharger. If you want to go from there, you can stroke, heads, and cam but it should be done at the same time because the choice of heads will change depending on the displacement. Also, if you are going to stroke, heads and cam, you will also need to have long tube headers and a tune or you will be dissapointed with the output. If you stroke it, you will need a new forged rotating assembly (crank, pistons, rings, rods).
So the bottom line is if you want to keep your stock parts, change the cam and consider long tube headers. If you do a search, you will see some impressive cam only cars on the forum but not a single stroker with stock heads, cam and manifold.

Hey, I get to post in tech.
Last November, I bought a used '99 6 speed with a 383. It does use a bit more oil, probably half a quart every 1500 miles. I have only driven it about 20 times due to emissions problems (the tune was messed up).
As stated, it really doesn't make much sense to spend a few grand to sdtroke a motor only to put the original puny brain back in and not let it breath. You really do need to upgrade if you go with a stroker. I followed a NA vs. FI thread and took some good info from that.
BTW, the dyno sheets that came with it says over 525 hp. The best is the torque - over 575 ft lbs.
Possibly a dyno queen since these numbers seem high to me, but that's what I'm sticking with because it sounds cool.

Stroking your engine and keeping your stock parts is like buying 20 gallons of gasoline to put in a 10 gallon tank. You'll overflow and waste it. 
Why do you want to stroke your engine anyways? Is it time for a rebuild?

as everybody else has said...33 more cubic inches isn't going to be a significant gain for the cost... A set of AFR205's and a good cam will get you a heck of a lot more power
