Im rebuilding my ls2. Im putting in darton sleeves and i want to know if i will be able to put a 4.250 stroke in it. What is needed and i also want to spray a 350 shot of nitrous. any suggestions?

 

hmmm, 4.250" stroke, plus 350 hit. Make sure you set your compression height to be able to handle it. Other than that, I don't see a problem with it. You should be able to use the stroke as long as you have the Darton LS7 sleeves, as they are a bit longer and will better accommodate the stroke..

 

We have a 460ci you can a run up to a 200 shot on but 350 is beyond what we would recommend.

 

what do you mean by compression height? What is recommended

 

a really short connecting rod.....

 

So what connecting rod would be the proper length? If compression ratio has anything to do with it i looking to run between 12:1 and 13:1

 

Look at the ERL 500CI setup....

Like Haans and Blanco said 4.250 and a 350 shot probably won't play well together due to the piston being too weak. I would do a 4.000 with a 6.100 rod so you have a really strong piston. 350 is a lot of NOS. If you can stay lower on the spray you could run more stoke and the necessarily shorter piston maybe.

 

Thats part of the problem, a really short connecting rod leaves your piston falling out of the bore, while it may only look like a small amount, the taper of your piston is generally to the bottom of the skirt. Once that area exits the sleeve, pretty much a trainwreck at that point.
