im going to install a big block into my 93 car on motor plates. i have a k member with off set rack bushings installed so that the rack sets lower than its made to and the motor will not go to the angle i need . i found a set of k member 1 in spacers does any one use this in a fast car. im going to be running true 10.5 my motor is 547 ci with A trick flow heads and intake. i going to spray alot of nos on this engine any one think that i would be better to have the spacers or the angle off thanks
