I just got the following rotating assembly for my 94 Lt1:

Callies Dragonslayer 3.750" Stroke Crankshaft, Compstar 6.000" Connecting Rods, Diamond Forged Pistons, Total Seal AP Series Rings, Clevite Main Bearings, Clevite Rod Bearings

Any idea how much nos it can handle?

 

Stock Block?

 

yeah stock block. looking to shoot 250 maybe 300 shot. But this would be only on occassion at the track or some fool who wanted to race.

 

glad t see you come over here and ask. you will get a worth while answer.

 

should hold are you talking about off the shelf diamond pistons or custom? what about pins?

 

Why dont you ask Diamond them selves?.

 

I plan to call them just wanted an opion from you guys.

 

If they are off the shelf Diamond pistons I would say 200. If they are customs they can be set up to handle whatever you would like, so the sky is the limit.

 

sounds alot like youre building my motor but for n2o instead of boost. ive been told mine will hold 800 rwhp

 

i just called em, was told i'd b fine with up 350 shot. I ordered the rotating assembly threw victory Racing. GREAT COMPANY!!! AN GREAT SERVICE!

 

Goodluck with the setup.

 

Are they custom pistons? What part number? 350hp seems like a lot for a shelf piston that typically has a .230 down top ring.

 

yeah custom pistons for nitrous. I just wasnt sure howmuch theyd handle.

 

What tis the thickness thrugh the crown and how far down is the top ring?

 

I'm a bit surprised to see a 6.00" rod in a 383 nitrous setup. With the 3.75" stroke, that pushes the wrist pin high on the piston, reducing the compression height. If they are truely "nitrous" pistons, good for 350HP, they will have the ring pack dropped down to get the top ring away from the heat, and strengthen the top ring land. That's going to be a very "wobbly" piston.
