r u kidding me???? look at his mods
lifters/rockers arent goona do anything
ls6 intake and tb
pace setters lts
full exhaust
slp induction
now if you add a cam like the vindicator (known to make great power) and as casts (also known to flow great) isnt goona make 500rwhp? ok can we agree on 480? i emailed vengeance a while back, dont have the dyno anymore, but the vindicator and as casts made 460 rwhp with just cam, heads, and a fast 90......i think the car had a lid also.......through an M6. depending on what "other supporting mods" he has, if he went with the vindicator and as casts he will see 480rwhp, if not a little more.

This thread is full of a bunch of useless information. He is rebuilding the bottom end and his question was is a 383the kit worth it. Y'all are talking about heads and cam and bearings and ****.
OP, to answer your question, only you can decide if it is worth it. You will see around 40rwtq increase across the whole power band. What you need to ask yourself is "is more torq and more potential worth $2500?
Personally I think it is worth it.

Please explain. Are you saying an identically driven 346 rebuilt with similar components to the 383 will not be as reliable/strong as the 383 counterpart? All I've read about a 383 is that the piston has to travel further in the same time, contributing to greater cylinder wall wear. What am I missing? I'd like to learn more about this
Plus the 383 will net increased torque and hp thoughout the entire rpm range. It will have more potential hands down.
With a balanced rotating assembly and properly built motor, this really isn't much of an issue. If it was we wouldn't see so many stroker engines. Stroker motors are about as common as silicone tittys, they're not that much of a problem.

Not 100% sure on the full budget yet, what I plan on doing is taking it apart this week, checking everything and see if it all checks out. And if everything is 100% I am going to reuse the stock rotating assembly. I will only buy the stroker kit if I find something wrong, because I really don’t want to spend all that money. I don’t plan on spraying the car at all so I am not worried that much about the bottom end and most of the cars life is going to be on the street. I appreciate all of your guys input and suggestions.

Consider this.........
More cubic inches almost always makes more average power than the smaller alternative.
You cam it correctly with a LS6 intake even with stock heads 450rwp is a pretty good assumption, torque down low will be abundant and flat.
Get a later set of 241 heads with a good valve job.
Car will run good with the inches.

I'd rock 383ci over 346ci in a heartbeat given the opportunity. Even if you have to reuse the heads you have at this point, you will still see more torque everywhere and make an all around more streetable car than a heads/cam 346. Then later down the road, put a good set of heads on and a more appropriate cam and you will waste anything the 346 could hope to be.
