Well Wrenchbender, I know you are right. Went through a lot of work, hassel and $$$. Don't have any more to spend. So when the check comes how should I set up a 350 for mileage. The problem was that the computer that was in there was set up for high altitude and got lousy mileage. Now its toast. Shorted out. Should I have gone with a modest carb and an aluminum manifold or a stock 4 bbl manifold with a spacer plate? I was told by a retired shop machanic and machinist that lives nearby that a Crower Baja Beast cam would make it better running and more economical than even a 305, otherwise just stock would be thirsty. I had a Baja Beast cam that came in a 25' motorhome with a Ford 390 in it and I got from 10-11.5 mpg with that heavy rig. It was a chassis pick up mount. Thats better than most motorhomes get. It had 4.10 gears and a C6 tranny. I think it had a 600 cfm Carter on it before Edelbrock bought them out. I put headers on it and it climbed the hills better than a stock set up did. Yet it idled smooth with no lope to it. Would this work for a 350? Any other suggestions you can make would be a great help. I'll have enough to buy another engine when the check comes in next week. Any hints as what to order from the machine shop. The one I will use this time gives a 7/70 warranty. Can get a 100,000 mile warranty for some extra $$$. Same engine just a longer warranty. 7/70 is just fine. This will be the last engine swap on this rig. You can answer here or email me. I have a set of 8.5mm Red MSD wires and Off Road control box to go with it. Hey Big Chevy 3600, I like your comment. Some truth in it for sure. Oh BTW, The Chevy dealer has a Goodwrench 350, 290 Hp. The counterman, I used to be one as well as a machanic, thought that on the hwy 18 is possible with my truck. What do you know or think about the one I just mentioned????? They sell a ton of them at the dealership. It has the older style manifold bolt pattern which I need. They have a bunch in stock at all times including the HO versions which I don't want. Just thought of that. Maybe the practical thing to do. Which is better? A new a new Goodwrench or a custom built from a machine shop for stock applications? I respect your knowledge and opinion. Some real good people here on this site. Bolters rule!!!
