Love my 460 motor..just to stay up to speed i added a manual choke cable to my carb its like night and day does not high idle as long .I Totally have control over my cold starts...and yours sounds like a Boss good job.
OMGosh Bro you just made my day i have the same year RV and i did the same job on mine only i have a flowmaster /flowmonster 2 chamber muffler on mine 3 inch pipe... and i just had my old Holley 4180 carb rebuilt on it and i love the way it sounds.
