Hi! When you guy's are posting 8+ miles per gallon that must be without the genset running or a toad. I'm in the process of doing all that is possible short of gear vendors ($3000 add on) to improve my milage. Currently with the toad and genset I'm getting 5-6 max. At 3.00 gas I may have to park the 345 and just look at it.

If I put regular or mid grade fuel in the tank, engine pings and diseling upon shutdown. My 345 - 454 is equiped with overdrive and banks emission, but runs for crap on regular or midgrade. When traveling with jeep wrangler in tow only achieve 6 to 6+ miles to the gal at 63 to 65 miles per hour. Any sugestions to tune the beast to accept regular gas? Note: when traveling at said speed, only runs at approx 2700 t0 2800 RPMs.
I think the question Chaplain Kent needs to answer is how much does it cost for an engine rebuilt

Since it was a servicing error that ruined his engine, it cost nothing since insurance paid for it. Now my Isuzu Diesel has 130,000 and is just nicely broken in. No tune-ups required either. Also, I get 12 to 16 mpg. Genset is propane. 12 is when towing our VW Jetta Diesel.

Engine tunes up are cheap in 454s. Cap, rotor ($25) , plugs ($1 ea), oil filter, oil ($25), thermostat ($6)....takes about a hour to replace and time.
No biggie.
I get a consistant 7.5 - 8 mpg plus in our 345 when towing our Beattle. I keep it tuned, replaced the ignition (to stock) added headers, 2.5", H pipe, rebuilt carb. I also run regular pump gas.
I think the biggest thing I do is keep it between 55 and 65 mph when travelling.
