Caution on CBM, i say this to anyone that has purchased an LSI motor from CBM, check your block ID #'s, they buy the 5.3 LQ motor, bore it out to 5.7 and call it an LS1,
I found this after a purchase from CBM, i called them on it and the comments i got back is its the same as an LS1 motor, yea right
Bottom line i can't sell it as an LS1 because the block ID # says it a 5.3, buyer beware of CBM and check your block ID #
