The cover is a PITA to get on/off, I'd have to order antoher gasket, etc... I assume the new gasket is a few ten thou thinner. Cheap SOBs.

I didn't take a good photo of the mod, but you can just barely see it here: http://wps.com/AMC/1970-AMC-Hornet/images/engine-pluggy-side.jpg from this page, http://wps.com/AMC/1970-AMC-Hornet/May2005.html describing "dropping in" a late 258 into the older chassis. Drop-in, assuming of course you don't count modding the valve cover and moving the engine/trans forward 1". The modification was fairly easy (meaning under 4 hours). I took about 1" of height off the back end of the valve cover, about 2" in from the back. A rectangular section, with a hacksaw. Filed it square. Then I bent a piece of 3/16" aluminum in a simple "L" that bolted inside the valve cover to block out the rectangular notch; filed the "L" 'til it blocked out the cutout section neatly, then screwed and epoxied (JB Weld or that other one like it, can't recall the brand) it smooth and level. Once cured I painted it wrinkle black. It's a pretty kludge. Still had to move the engine forward 1". I also drilled a 1/2" hole just above that back valve cover bolt, inside the wiper motor box, so that I can reach the bolt vertically with an allen wrench. No way you'd ever get a wrench or nutdriver back there otherwise. It's tight, but reliable, plenty of clearance, and servicable. Still pisses me off though. I should have got an older head (I'm carbed) or switched to EFI, but I didn't want to deal with the "oh, it's a drop-in" issues regarding brakes, spring towers, etc... _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.wps.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
