gas mileage Mechanical vs Vacuum Secondaries

Ramcharger, it's kinda rude to just ignore it when your mistake is pointed out and evfen more rude to make excuses while still not admitting you are wrong. LXguy was right on target.

I think it's kind of rude to think I was ignoring LX when in actuallity I had worked 21 days in a row and was trying to do dishes, clean around the house, deal with an employee who just lost an inlaw and was trying to figure out how to get bereavement PTO, etc.

Don't make assumptions.

Both of these statements are 100% true. All QF metering blocks also have changeable PV restrictors if needed. Also, on my 4777 I never had an issue with stumble on tip in after the correct size squirter nozzle was installed. At cruise, I'm getting about 12 MPG. Not bad for a full time 4WD (all four wheels are driven all the time) 5600lb truck on 33x12.5's and 3.55 gears with the aerodymanics of a brick. Before the engine was rebuilt and I was using the factory 2 barrel I was getting about 9 mpg. By comparison, my 2001 fuel injected 5.9 Dodge ram part time 4wd with 4.11's was getting 14 mpg at cruise. The ramcharger would smoke that truck anywhere in the rpm range too.

The intake manifold and carb are actually too small for this engine too. It breathes hard even up here in the rare air.

Like I said before, MPG and driveability with any given carb and engine combo depends entirely on the build and the skill of the tuner. I can wood the accelerator on this 360 at idle, in a way heavy vehicle with automatic trans with a less than optimum rear gear and it just plain moves. Even holley says this can't be done, I'm saying it can. Most likely a lot of people couldn't pull this off, I'm just saying that it can be done without resorting to using a drill. Here's a video and you can even hear the squeak of the pedal when I mash it.
