Owners of Dodge based RV's?Pugmaster, I am well aware that the exhaust manifolds on a 440 (or 413 or 400) are Nearly Impossible to work on, due to Clearance Problems. That's the very Reason to Trash them, and get the Exhaust Headers. However.......... they are only available for 1977-1981 Class C's. I refer to Hedman "Hedders", Part # 79220 from Performance Automotive Warehouse for Aprox. $200 or less. (Also, for the small block 273-318-340-360 's there is the Hedman Part. # 79030, for Aprox. 150 or less.) AND, there are other Models for Class A Dodge MH's.Re: How many of us are there? Owners of Dodge based RV's?Hey, Dodge-ee-o's, glad to chat. How 'bout this deal: Hedman Hedders are available for the 318-360 engines, AND the 413-400-440 Big Blocks. basically, this could easily result in horsepower boost of from 25-50 extra horsepower, AND more Torque AND Better Fuel Mileage. Keep up the posting, and keep the faith.Re: How many of us are there? Owners of Dodge based RV's?Howdy! You have inspired me to talk about my 77 Dodge with 440; it's a "Fireball" 24 footer. I would like to establish contact with you regarding the Dodge Rigs.
