It's easiest to order it in "kit" form. Just look for an LS1 stroker kit with a 4" crank. Have your block bored to the specs from the available pistons from the kit (they usually offer stroker kits with .010, .020, .030, etc sized pistons). I believe most strokers I've seen are 6.098 rod length if I remember right... Just depends on where you want the pin to be.

 

here is what i found.. dished 3.902 pistons.. 6.200 H-beam rods.. 4inch crank.. Think this will be ok or do i need 6.125 rods

 

I like this idea, 6.0 around my area are 1200-2000 dollars but i can get 5.3 all day long for 200 complete so thats an extra 1000-1800 in spending cash for parts that i would want in a 6.0 anyway for nitrous or FI. sounds good to me!
Where is a good place to look for a rotating assembly kit? cant seem to find any.

 

Factory 5.3, 5.7, 6.0, All use a 6.098 rod. Factory LS1 Bore is 3.898 Wich is also avalible. You will need to match the rods to the pistons you decide to get. Find out what piston and rod combination is available for a 4 inch stroke. You really should buy a kit as you will get everything you need and it will all be properly matched. You can usually save a few Hundred bucks that way too.

 

cool.. so who makes a good kit.. needs to be able to handle boost and spray

 

You will have to Shop around. Try Ebay or hit up the sponser on this site and see what they offer....

Those appear to be for stock rod and stroke, not a stroker 4" crank. Search for "stroker LS1". Any listing you find should say that the pistons are for use with a 4" crank and specify what rod length the pistons are made for. You may just email the ebay user and see if they sell the Probe pistons for a stroker LS1 with the same bore and a 4" crank, or perhaps they have the whole kit for you too...

 

Cool.. thanks brothe.. gonna be boostin and sprayin.. want it to handle it
