ok if i install a stroker kit what needs to change? i have a LS6 block i want to install a 383 stroker kit?? help plsss

 

Think your going to need a 4.00 inch crank, upgrade the pistons 3.9 and new rods 6.125 shoudl be cool

 

You get the assembly, take it to a reputable LSx motor builder and have them put it all together.
4.00 crank and 6.125 rods are a given, choice of pistons and rings depends what you want to do with the stroker. (boost, nitrous, NA, size of cam, CR requirement etc...

 

if you have to ask these questions....just buy a 383 shortblock complete...you will be way ahead...trust me.
