Contact member MasterBoondocker. He is a TQ expert, and let him rebuild your carb. That IS a spread-bore 4V, PERFECT for this application!
Exhaust manifolds should be very easy to find. So many street enthusiasts throw them away for headers, so look at Mopar sites (www.moparts.com is a GREAT one) and find a pair. Craigslist, too!
Go to www.summitracing.com and buy your engine parts from them. Use their "Summit" brand cam, timing chain set vs any other. The quality is VERY good and pricing is VERY affordable. Buy only Clevite 77 (sp?) bearings, Fel Pro gaskets, all from Summit.
And 9mpg is nothing to sneeze at in the world of RV's! :B
