I currently have a ms3 cam on stock 241 heads with a hsw wet plate kit.

this winter I would like to just beef it up a little.I would like to just build it to handle a 200/250 shot. Right now I have a 150 shot on it, and im tired of it and want more....but dont want to take the chance on a stock bottom end.

so, what is the stock ls1 connecting rod length, and piston size? I would like to spend around $1200 at most. I will also be adding some prc 2.5 tsp heads down the road as well.

Stock rods are 6.098 and pistons are 3.898 for a 346

thanks.

and whats better? I beam or H forged rods?

what about CC's for the pistons?

H beam rods are better.

H beams are rated at more normally, I beam's are cheaper and will normally do the job depending what kind of power you want. As for what cc's it depends on what heads you run and what length rods you run. With that determined you can determine what you want your compression at and get pistons accordingly

I am looking at forging my stock ls1 and keeping my stock 241 heads on the car. I will be putting a master power t76 on the car. I would like to be between 700-800rwhp after its all said and done.

so, if you guys were in my shoes, looking to do a "budget" forged build on a stock block ls1, with stock 241 heads, what setup would you recommend?

R u planning on honing the block?

If it were me, I would sell the LS1 shortblock and do an iron 5.3L block bored to 3.90" with Wiseco pistons, Eagle H beam rods, and the stock crank. I would use ARP studs in the mains and cylinder heads, and good race bearings, like ACL or Clevite. Even though it would be a 3.90" bore, I'd still probably even go with LS9 headgaskets as well.

yes, it will be honed even tho it has less then 40k on it.


I will not be boring it. No need too.

In my opinion you should look at the Wiseco flat top pistons, and an eagle 6.125" H-beam rod with the ARP 2000 Rod bolts. This setup from us comes in at $1249.99 and I know both parts can handle that kind of nitrous no problem. I would also recommend looking at doing an ARP main stud kit at the same time you do this other work. It would leave you with a bottom end that should be rated to around 900.

this is the type of answer I am looking for, but I am removing the nitrous off the car and looking to put a single turbo on it. Most likely in the t76 ball park. Looking for reliability but the capability to handle more power then my goal of 700-800rwhp. I want to keep the stock bore on the ls1, and stock 241 heads if I can.

does that come with bearings and rings? im lookin to forge my motor too over the winter or next spring for my D1SC. Can you get by with just a hone? or would a slight bore be necessary?

sry for the hijack lol

I am still very sure that those parts could hold that power. If you are looking to drop the compression for the turbo Wiseco also offers an -11cc dish with the steel top rings to handle some boost. Those pistons would easily be able to handle 20lbs of boost if needed. I would recommend at least honing the cylinders a little bit, Wiseco's pistons are a 3.903 bore and you want to be working with a fresh surface for a build like that.

For that price I did not include bearings but the clevite p-series bearings are $113 for both main and rod. We don't bore LS1 blocks very often at all, mostly honing because the sleeve doesn't allow for more then that.

kidcamaro98

iTrader: (8)

exactly what I was looking for. I will just be doing a good hone, even tho the motor has less then 40k and it and prolly doesnt even need it.

now, I am curious about my ms3 cam. How would this work with boost? I know it would bleed off boost, but how much? Can I still reach my goals? The car is mostly a street/highway car anyways.

what compression ratio would I be looking at with the -11cc pistons and stock 241's?

so for 1500-2000 plus a set of ported 317's youd be looking at 2500-3000 if your doing the labor yourself...oh im also including new rockers and lifters in that too. this is a great thread btw. texas speed gets my vote. the 228r is monstrous.

hey i looked on your site and cant find the setup your talking about, but i purchased the rods already. can you send me a link or a part number to the pistons that you are recommending. thank you

Very good info here from the guys at TPS.

Do you guys have anything firged for a stock ls1 bore? I've got a 5.3 block I'm planning on taking to 3.898 and a turbo down the road. And also with the 6.125 rods would I have to do anything to get those to fit? I'm unsure of head choice at this point also.
