Has anyone built a solid roller LS1 408 CID or bigger and added boost yet ?

If so what were the results?

 

Why do you care if its 408+CI? Some of the fastest LS1s out there are 346-370

 

Steve turley has once about that size, it's making about 1600 at the crank and over 1200rwhp

 

i was gonna do a 408ci with a T88 but decided to step back to a 370ci with a T70-T88. just havent deciced what turbo i am gonna run. really depends on how streetable i want it to be. some times tubo lag is like traction control...

 

If the goal is big power on pump, then it makes sense to spend on cubes. I think Dalipalarso (sp?) was going with an HPE built shortblock 408, hydro roller. Pure Evyl is 408 short block too, T88 is going on now as well. I seriously doubt you'll need to spin a 408 to 8400 to make gobs of power, unless this is pure out dyno/trailer queen and 1/4 machine.
