I have to concur with diametricalbenz: replacing this engine just isn't an option, especially given that the interior is just too sun-weathered to restore without a complete gutting.
Thanks for all of the suggestions. I'd love to find a little '82 5-cylinder to beat around in, but I do have a '72 bug that I could spend some time (and probably less dollars) with. Is it sacrilege to step down to a VW on this forum? ;-)
Nah, I don't think anybody cares if you jump to VW. I don't know why you'd want even LESS horsepower
but I think the unwritten rule around here is "restoration and or modification" as opposed to putting exhausts and stickers on them.
