also keep in mind that if you havent changed you speedometer gear(like I havent), youre actually getting more than the 130-140 miles you odometer is reading, and your speedometer reads about 7 MPH fast.

Love to hear that throaty roar coming from the snorkel when the Holley needs lots of air cause the skinny pedal is out by the radiator!...lol
Can you post up a picture of your setup? I am in the mood to change my intake and carb on my 4.2 but not sure which one to go with, and also why kind of snorkel did you buy? I'm very interested lol

I'm thinking about purchasing a 95 YJ, manual, 4 cylinder. It currently has a 6" lift (and gets 12-14 mpg), but I want to return the jeep to it's regular driving height and use regular tires. What kind of mileage can I expect? Most people posting either seem to have an automatic transmission, or have lifted theirs, so I'm a little bit lost. Thanks.

Yeah before I had 3.07s and it showed slower than I was going, now with the 4.10s it's faster. I've done the math at a few different speeds compared to a GPS and its about 15% off at any given speed so to estimate my gas mileage I take the mileage the trip odometer shows and multiply it by 0.85 to subtract the 15% difference. Seems to be close enough for now until I get around to swapping out the speedo gear. I'm thinking about upping to 35s before swapping the gear out.

Only question is if the 35s will fit once I trim the rear for TJ flares with a 4" RC lift or will I need more than that to clear the 35s with full flex.
