I'm a big fan of the SL 500, 90's styling, even to the point of contemplating buying one when looking for a second car recently. It's inevitable that some time in the future, not just yet, with the prices falling the way they are I will seek out and find one of these well put together GT cruisers. The point of the post is, I need to be pointed in the direction of any 90's 500 V8 rebuild manuals, videos, memrobilia etc as one day I'd like to have a go at rebuilding one of these 4 cam motors. Are there any engine enhancement goodies available for the 90's era SL 500 V8. Do they respond well to upgrades. Thanks.
