my 93 bd 4" on 19"S without a z'ed clip, dropped the motor 1" and built a new control arm x-member, did not section the oil pan ,the pan pretty much sits on the ground, still cant fit a stock hood.....
mine's just to the rockers, engine's dropped a little though.. and the cross section support under the hood, is trimmed where the intake tube curves. still gotta Z it though.. then id probably need a cowl or something.
