    Ebay SS shorty headers 350 TBI

    Any headers that use the stock tiny Y pipe, in my opinion, are not worth the money. The Y is still a choke point. Hard to justify $300 for 5hp if that. Long tubes and an off road Y pipe is the only way to go. Long tubes improve scavengining, and a 3" y pipe to a flow through muffler like...

    Towing capacity for 2door tahoe

    And heres the picture of it towing my camaro. I miss this truck, from 05 until this year it wasnt garaged, and years of OBX beaches and CT salt started to take its toll. You can see how much more squat it had with the camaro behind it, because of the way the uhaul trailer makes you pull the...

    Towing capacity for 2door tahoe

    My dad bought a 95 Tahoe new with 3.73s and the tow package, 350/4l60e and it had his 19 foot Grady on a tandem axle trailer behind it for the first 90k miles if its life. Normal "to the lake" weight was about 4500lbs, but every year we towed it from CT to NC, 14 hours in 100 degree July heat...

    Can someone explain CatBack to me?

    You need either an X or H pipe to keep the pressure equal. X pipe and H pipe will give different sounds, H pipe having the more "truck" sound. X pipes are more commonly used in cars. "Catback" means from the catalytic converter, back to the tailpipe. These are emissions and 50 state legal...

    optimal MPG mods

    For the question about adding another lower air dam on a stock height truck, I dont think that would help mpg since you would be increasing the frontal surface area of the truck. The stock front air dam, looking at it from the front of the truck, covers all of the front suspension and is the...

    Pros and cons of mpfi over a tbi

    I'm trying to get used to my vortec 350 as I've only had TBIs for years, the vortec pulls hard from 3000-5000 where the tbi falls on its face at 3000, but the "get the boat out of the water, yank a tree stump, get moving and snap your neck" torque of a tbi 350 from idle to 3000 isn't there with...

    Project "Vanity Yukon" my first vortec 350

    With the new CTS the truck runs mint now. Runs at about 215 degrees instead of the 175 it was running at before because it was so rich. Drove about 100 miles today and it really is a great truck.

    Blue95 I backed up everything you said. I just helped explain why adding a sheet of plywood increases frontal area. I'm new here, I have spent the last 8 years on LS1tech which if anyone's goes on there is full of aholes, I am sorry I jumped to the LS1tech thought train and was rude, but I...

    There is so much stupidity in here I can't keep myself from commenting, like when idiots argue that increasing minimum wage is a good thing. I am a mechanical engineer by degree and career. The air dam is to move air around the vehicle instead of under it and create a low pressure zone...

    They didnt give the Tahoe the z71 option until they did the 99-00 leftovers including the limited.
