Re: [Chevelle-list] tuning
I got excited about gas cost until I did some math. If gas went from 1.80 to 2.20 per gallon and I got only, for easy math, 10mpg, that's only $.04 increase per mile. On a 5,000 mile trip, which is some serious saddle time for a 10mpg rig, that's an extra $200. Money's money but only an extra $200 on a run like that would not make me panic too bad. Lot of ways to make that up..don't feed the spouse or kids at a few stops. Not talking about maintaining a happy home life, just saving money. Or only take roads that go downhill. Don't forget drafting ( aka tailgating if done under 100 or so mph ) - Original Message - From: "mike f" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; "The Chevelle Mailing List" Sent: Wednesday, May 04, 2005 10:18 AM Subject: Re: [Chevelle-list] tuning I have heard the Vortec V-6 will fit.

Is there such a thing as tuning a car for maximum mpg by maybe sacrificing elsewhere such as power or acceleration? My gas-eater will be going on a 5000 mile journey this summer and I'm trying to do what I can to avoid seriously depleting the world's oil supplies (not to mention my wallet)..
Re: [Chevelle-List] tuning tips anyone?
Hey Rob, Thanks for your input. I like the goin' fishin' analogy. Thanks for the tip on jetting. The Holley manual for that carb suggests jetting down 1 step for every 2000 ft. but it sounds like that might not be the way to go. If I do try that and get a stumble I'll know what's going on. Looks like I just need to play. Wish I was rich, the chassis dyno I mentioned in earlier posts can be rented for $600 per day. That would be a great way to quantify any changes besides seat of the pants.

Re: [Chevelle-List] tuning tips anyone?
Hi Bob: Even if someone had a BB with all of those parts, it would be a different setup because of the tranny, the ring and pinion gear, and so on. 1. Get in that: I'm Goin' fishin' mood, you know: I'm going to waste away the whole day, but I'm not a bum, because I'm fishin'. 2. Find some isolated area, away from residential, where you can tear off a couple of gears. I have a freeway on-ramp. 3. Change the total timing in two degree increments. Start at 30 degrees, run up the ramp, then again at 32, and so on. Jot down your impression of each timing setting. As you get away from the ideal setting it should become obvious. 4. The same idea with the jetting. Jump two jets at a time, starting with the stock jetting. Leaning a Holley, most often, causes undesireable effects, such as bog or stumble. Even for your elevation, never underestimate a Big block's love of fuel! A stumble is a "too lean" condition, one hundred percent of the time. I will go out on a limb and say that you cannot make a engine fall on its face with too much fuel. A too rich condition will cause a loss of chrisp acceleration. You will sense that the engine is cleaning out through that too rich part. The most common over rich error is over modifying the accelerator pump, most all other errors are too lean. If you have a big cam, and/or headers, the engine will want more fuel than what Holley jetted for.

[Chevelle-List] tuning tips anyone?
Anyone care to share their tuning specs if they are using a Holley 770, Performer RPM intake and MSD distributor (on a big block)? So far I have tried 32 to 38 degrees total timing, left the blue bushing in the distributor and changed the springs to the light blue to get all advance in by 3000 RPM. Left the carb jetting stock (probably could lean it out some as I'm at 4800 ft.) Haven't seen much in the way in performance increases so far.
