Watch out for the ping monster! In my '87 Comanche I went to NGK BKR6EK (new number 2288) and I don't run an EGR valve with a shaved head. I sometimes get ping, but only under extreme conditions (like dragging a 1 ton Ford with 12' flatbed up a gravel switchback with a 20+ degree slope) It's the plug the BMW guys are running to get dual grounds and run regular gas while still getting power to the wheels. I'd put EFI on the Sundancer in a heartbeat! (bad weather and lack of time has kept me from doing up the Spirit by now!)

What would be a good fat-gap spark plug to use with such a beast?? It also has a Clifford intake, Holley 2300 2-bbl, and a Clifford header. Any advice appreciated. Thanks in advance. George Graham AMC of Houston Btw, I took my recently-acquired Eagle Sundancer on its first outing to a couple of local cruises last Saturday evening. Drew lots of gawkers, and had lots of folks scratching their heads. What fun!! Only thing I've done to it so far is replace the original fuel hoses (they were all ready to blow). Still needs a few nits to be dependable -- alt belt, and carb overhaul (and open up the idle bleeds a tad), and a few miles of rotten vac hoses to replace. -------------- next part --------- _________________________________________________________________ Connect and share in new ways with Windows Live. http://www.windowslive.com/share.html?ocid=TXT_TAGHM_Wave2_sharelife_012008 -------------- next part -------------- An HTML attachment was scrubbed...
