Texas Speed 383 W/comp 244/248 in WS6 Just finished up putting a friend of mine 01 WS6 back together, after stock LS1 came apart (see pics).. Factory block was done.. So got him to bite the Bullet and buy a Texas speed long block.. Motor is a Forged 383, with Stage 1 Ls6 heads, Comp 244/248 .612"/.615" 112 LSA.. Kept the LS6 intake, installed Racetronix 42lb. Injectors. car also has QTP LTs, Magnaflo catback, and it is a 6speed car.. Added few pictures of old motor and here link for video of car running with new motor..

I have no idea how it happened.. he said he went to start it up one morning and she cut right back off.. not sure what came first.. chicken or the egg.. rod has clean break and piston is broke.. but was very hard to believe since car is easy driven (since he's owned it) and only had 65,000 on it.. I've put hell on 150k motors and nothing like that before..
