ls block on an si tranny???

 

NOPE, you cant bolt up a LS block on to a D series tranny, unless some one rigged up an adapter plate to it

 

not happening mang

 

if you are talking about a 99-00si tranny then yes it will. but if your talking about a single cam si tranny then no it will not. also that is one hell of a combination if you do it. get ready for crappy gas mileage and the land of 4500 at 70mph. but it realy wakes up the ls.
