damn, wrong button again. anyways lima is right if its a sport 400 (like a trailblazer) then its not what you want for a work vechicle. i reread your post and, duh me, it says a sport 400 so i should have said no in the first place. my brain cramp.

 

Hey guys not your fault with so little info on the 400 i just got carried away telling story of the deal my bro thought he had found, it turned out to go good for first 6 months then lost compression i re ringed it and ti went another 8 months i just made the post so long i guess i confused you all............GOD Bless You all...................williebee
