it is posible to make 425-450 hp on a ls using this set up

84.0mm b18a,crower rods,cp 9;1 or 9;8
presicion sc61
full race manifold
presicion ic(dont know what measure to use yet)
hondata s200

now what is left is the head,if somebody can point me in the right direction i will apreciate that,did a seach but couldnt find anything,

 

I hope you get replies to your post but it's unlikely. Your question is just too vague. To answer your question as best I can without knowing all the variables, yes you can make and support that amount of power.

 

tuning will have to perfect......i would look more in to the head also..since LS heads don't flow that great...do more R&D on a setup....

 

get a jice setup onthe head like crower turbo cams, and a jg manifold, you may be able to push what you want to get.

 

It'll never happen until you get some injectors
