How does this sound guys:
Forged 346, Lunati (or similar brand) stroker 383 kit, 90/90, MS3, Terminator 200CC heads, all ARP heardware, textralia, 9", and maybe spray we'll see if i need it...
this plan is tenative of course, and can change, any recommendations are welcomed!

yeah...my only thing about the 402 is swapping parts....i heard the 408 is easier for that....anyone want to chime in on that...
Also, whats the deal with engine covers...i hear t hat all the time what the hell is that...those fuel rail covers or something??? anyone know what im talking about

Engine covers, like the timing cover, valley cover, etc.etc. Yes, a 408 will accept more of that, but SDPC sells a ls2 engine cover kit that has all that stuff in it, that's pretty inexpensive, that along with the block price difference from the iron to the alum is only about 600 bucks.
I still think the 402 would be a better deal, in the long run you won't regeret it, unless your car is down and you need it, I'd take the extra time and go for the bigger CI, I dont' know anyone that ever wished that they went with smaller displacment... only people that say " god, if I spent another 800 bucks I could have gotten a 402 instead of a 383"
Think about that. Plus, like stated above, you will be able to make more power on motor then you are even looking to make on the bottle, thru a 6 speed there's quite a few cars that are well over 500 at the tires on motor. I guarintee that you make 480 on motor with a 402, with the tq that will make all over the place in the rpm range, you'll scare yourself for a good long time with it.

i have a buddy that just got a 402 stroker.. I don't know what cam or heads he is running but he put down over 480lb/ft of torque through an auto and last time he took it to the track he let off at the 1/8th and still ran a 12.3 
. but then again his car is somewhat of a freak...he was running a pretty mild 228/229 cam and ported heads with his stock cubed LS1 and somehow was trapping at 124mph!!

didnt know there was a kit good to know...
I took a look at TSP's stroker 402...i have the MS3, id throw that in, unless I should spring for the MS4 at that point ya know...remember though I want to maintain weekend driveability..how are the PRC stage 3 heads that come with that engine..i was taking a look at the terminator heads..but i guess the PRC heads are better with the bigger valves etc....also what pistons woudl i go with the -2CC vavle relief?
THANKS! keep em coming

Either way way you go I think you will be grining from ear to ear once you get the motor built and run WOT. But I went with 408. Tsp!! See sig.. good luck.. If you should go 408 maybe call down to TSP and speak with Jon Reynolds .. there are two Jons now lol.. This motor was my first stroker (infact first real major mod ever) and Jon was polite and very eager to answer all of my questions.

I've had a 383 and a 408, my advice is a 402, hands down.
there is a lot of good advice and a lot of bad advice in this thread. if people don't know **** about something, they shouldn't post
keep your 1 3/4 headers, 1 7/8 will be a waste, especially for a daily driver/street car
you don't need big expensive heads to make good power, the fast 90 is a great intake, but it won't flow enough to utilize the better flowing LSX heads anway, so don't waste your money. you can make over 500rwhp with a $1500 set of heads
there is no comparision to a 402 making 500rwhp and a 346 making 500rwhp. the TQ and area under the curve difference is ENORMOUS.
going with an iron block is a very noticable weight difference on the front end and you would probalby regret getting it. people spend tons of money to reduce wieght on their car. its a no brainer to spend a couple hundered dollars extra and go with an LS2 block for that alone. the extra 6 cubes for a 408 is not worth the weight difference
as for your cam, i would highly recommend getting a custom grind for your application. don't just throw in an off the shelf grind. especially something like an MS3 meant for stock cubes.

hey guys, thanks a lot...i appreciate all of the feedback...
I do take everything with a grain of salt, BUT, it all helps!
I pretty much (but havent shut any ideas out) decided on a 402, i like TSP's longblock 402 set up...and yes i would go with a custom grind cam...not an off the shelf...the MS3 is going to go in my bolt on 346 with some terminator heads for now and probably some ARP rod bolts while im at it, why not...and the saving has begun for the 402.....completion- probably less than 2 years...we shall see!!!
Thanks a lot guys....keep the ideas coming!

what is wrong with the ZEX kit...just wondering...im open to all sponsors...all suppliers, and all ideas....
Lets say I go 383, will the power i leave on the table compared to the 402/8 going to be that much?
Also, if I go 408/2....will I lose low end streetable power...it is a street car that sees track 2 oe 3 times a year for fun
