just wondering if i can add a couple washers or something to raise my engine a bit? one of my LT headers knocks on the body, and i think if i raised it a bit, it would give me the clearance i need. my C&L intake tube also hits the fenderwell at idle which i hope would also clear if the engine was raised maybe 1/4". would anything negative come from doing this? i will be getting some aftermarket mounts in a month or so when i make my next order, but for now, will this work?
