oh yeah i forgot you were doing the same basic set up well you got twins and i got one. hey you got a link to that oil pump by chance please?
so alluminum it is then i know when i was lifting it to put it in the truck i could tell a good diff in the weight of this thing lol. it is ok to take it to 3.905 right? thats the only piston size i can find plus i want to clean up the bores.

 

Yeah I have my LS1 bored out to 3.905. Ill try to find you a link to the pump. I know its a surflow and is made for transporting oil. If I find the link I let you know.

 

cool thanks are you useing stock crank on yours??

 

Yeah im going to use my stock crank. I think they will hold alot of power but I think its the high RPMS along with high power that hurt them... 7000+

 

What kind of question is that Mike? Of course a turbo LS1 will kill a 408, even with a T-Rex, not to mention it will be just as streetable making 600rwhp turbo as it is right now. Did you figure out when were doing your intercooler? I cant wait to boost the Yukon.

 

i'm gonna cut it and shorten it and put it in hopefully. then get this damn thing boosted yeah i wanted the 402 but i like my 20+ mpg that the ls1 gets.
