Hey guys, i recently got my hands on a stock 2001 (20k mile) LS1 block, cleaned and honed, ready for assembly. I also have cnc ported 59cc 241's that im planning to put on this block.

Im at work, and did a little search - the results were inconclusive. Anyway, can someone or anyone point me in the right direction for a decent priced forged 383 balanced rotating assembly kit, from one of our fine sponsors? I found a Lunati kit for 3600+ messing around on google. Do rotating assemblies really cost that much? That seems a bit extreme, ive seen assembled shortblocks go for that or less. Any help would be greatly appreciated. Thanks in advance!

Check out TSP (Texas Speed) I believe they have a complete 383 rotating assembly for about $2200 all forged. Lunati kit is great but it is pricy.

Speed inc has a rotating assembly for a 383 that is a Compstar/Mahle combo for 2400. The only thing about it,it doesnt say if the pistons are forged. I would asumme they are since the rest of it is.

We have a Callies/Mahle rotating assembly for $2400. This includes Callies Compstar 4" stoke forged crank, Callies Compstar 6.125" H-Beam rods, Mahle Motorsport Inverted Dome pistons, rings, round wire locks, pins, and bearings fully balanced ready to go.

Let me know if you need help with compression ratio calculations and/or spec'ing out your combo.

Thanks,

Hey shane are the pistons that come with that kit forged also?

Yes they are. You have your choice of Mahle or SRP. I prefer Mahle over SRP for LS series applications. If you are going FI or a big shot of nitrous, I can do a deal with Diamond pistons for a little more money.

Thanks,

I went with a SCAT 4" crank, SCAT forged H-Beam rods, and Mahle 3.905" forged pistons. Ordered the crank and rods from my machinist (Eric Koenig at HKE) and the pistons from Scoggins Dickey. About $1,800 total.

I'd check with your engine builder. Most times they can get a better deal than you can individually.

One thing to make sure of no matter what route you go, get a balanced assembly. If you are price shopping make sure you are comparing balanced to balanced or unbalanced to unbalanced. With some of the cheaper cranks, you will spend a boatload of money on mallory metal to balance them. the Callies stuff comes with enough metal to balance an 1850gm bobweight and if you order an assembly, it comes fine balanced. Some of the cheaper stuff won't have near enough mallory which is one of the many reasons they are cheaper.

Thanks,
Shane

actually got one more, ive had a few ppl tell me its not even worth goin with a 383 cuz it dont add much hp but it does add torq, what do you guys think?

It will make MORE tq MUCH lower in the powerband so I think that alone makes it worth it. You will pick up a little hp as well but not like with a bigger bore. A friend on here is runnin a 383/5.3 PRC's/MS4/FAST 90/ bolt ons making 475 through a stalled A4 on a conservative nitrous tune. Full weight car running hi tens. It drives really good too and I see him on the streets around some. Built right your still safe spinning 7k too.

I am debating this same issue of going 402 and when I look at the extra cost of the shortbock it's not bad but when you throw in the sensors, hanesses, reluctor, some other miscellaneous stuff the budget really swells. I just wanna fun steetcar to run decent at the track so ***** to wall is not my goal. If that new FAST really works with the L92's though i might have to rethink and go bigger bore though cause I think shortly after that you will see some sick setups for relatively cheap HP to dollar ratio

Search WKMD on his l92 setup. He makes mid 500's hp and IICC makes more tq at 2500 than I make peak In a light *** vette that has to be a FUN ride His short block was a LS3 IIRC

What would a set wiseco's and their ring set thrown in bump it up to. I might start gathering parts and try have everthing to do it this fall when the Beaches slow down around here

Thanks

The part that you have to remember with going with a 383 is the prep work that's needed to be done on your block to clearance the rods. If you have access to having that done inexpensively, then it might be worth it. If not, I'd look into getting a balanced, assembled 383 shortblock that is ready to have all of your current accesories and cam/head bolted on.

Adding cubic inches is adding power. And tehn, when you upgrade heads later, you will already have a solid foundation to work with!

Don't second guess adding cubes like that.

The Wiseco's would be similar in price to the Diamonds I'd suspect. They are both great pistons.

Not to hijack the thread but how much money does it take and what exactly do they do to the block when they prep them for the new internals for the 383??? Thanks in advance.
