As soon as my engine is back from the machine shop I'm planning on tackling the 0411 swap and coil near plug on my 99 big block. I've got a set of L21 valve covers and without having the engine to mock it up, it looks like (from pictures) the bottom of the resonator is going to interfere with the coils on the passenger side valve cover. Has anybody done cnp on an L29 and if so were there any clearance issues? I'd rather not mount the coils remotely, I'm trying to keep it as clean looking as possible.
