You can build a 402 for much less than $10k. Your heads will have to be changed for better ones. Even LS3 heads will make more at a decent price.
Of course there is no substitute for bigger cubes (except boost ), so if budget allows do it.

I understand that u can build a 402 for cheaper but scoggin dickey said they can sell me a LS3 427 for $10k and that is complete motor with a FAST 102 and TB with injecters, shipped to my place. I just know ls3 stuff is the way to go anymore. Idont know really what to do though. i mean what is the hp & tq differnece between a ls2 402 and ls3 427??????

In my opinion, this is what it comes to .... how long do you plan to keep your car??? If you plan to drive and/or race it until the motor has no life left in it, go for the "427 crate". If you plan to drive and/or race it for for a year or two, get bored and sell it, go with the 402 LS2 short-block (actually, that is what I am running). You never get close to your money out of a heavily modded cars and, espeially in this and the near future's economy, it is even worse. Now, on the other hand, if money is no object, then it's a no brainer .... 427!!!!

ive had the car for many years now. i have no attention to sell the car ever. so thats where im at with that. but everyone want to make the most power for the cheapest price. so i guss what im asking is what kind of power can i get out of a 383 with my top, 402 with my top end , or just go all new with a ls3 427. where is my power with those options... id ask a shop but of ourse all shops want u to spend more money so im trying to findout from this forum what is the best way to go...

If you don't have a ton to spend now but want to upgrade later.. I would get a forged 427 or 416 short from tsp... stock l92 heads and l76 intake with a custom cam. Later when you have more money get the heads ported and either port your intake or move up to a 102 fast.
Just another idea for you to think about.

Perhaps you are not quite grasping.
It all depends how you build it but for argument's sake, let us say you build them all optimised, the 427 has the most potential.
383 close to 500rwhp
402 500>530 rwhp
427 550+
But this is built with the right combos.
IMO in your case, a nice 402 will do nicely.

I went 403 and it cost me a net of $600 more. A brand new LS2 block is $1100 and I sold my LS1 block for $500... I have TFS 220'S and would make an easy 20-30 more if I were M6. Small 1 3/4" headers, cats and Ypipe + catback all cost me HP but it is after all a streetcar.....
