Hi Murray.
Had to lower the crossmember 30 mm as UZ-1 was just a bit to tall, even with a moderfied rear sump, which is tight in against the cross member.
Fire wall clearance was tight too, 15mm from back of heads.
No buldge necessary, have removed sound deadner and cross brace for the moment as top of inlet manifold is quite close to bonnet, will re fit it later with a small piece cut out in the middel.
Steering was the biggest pain. With the crossmember lowered had to slide the lower bush in the column out by 8 mm and engine is off set slightly to the left.
Used "crown" log type exhaust maifolds. RH was Std, and LH had to be modified to suit.
where are you up to on your transplant ?
Regards
Andrew
