    Successful sound deadening for headers?

    Also during my research, it was suggested that Noico sound deadener is just as good as the Dynamat at a fraction of the cost. I bought some squares and will lay that down underneath the vinyl layer...

    Successful sound deadening for headers?

    Did you have a before/after comparison? I may do this as well.

    Successful sound deadening for headers?

    Researched for several hours. For pure sound blocking, you want mass loaded vinyl on top of closed cell foam. You can buy them as raw materials and try to combine them, but screw that. So I just spent the money and bought Second Skin Audio Luxury Liner Pro, which has the MLV on top of the...

    Successful sound deadening for headers?

    Ok the y-pipe connection is right in that area that has no padding. Must be it. I will give it a shot.

    Successful sound deadening for headers?

    Hey all, I am enjoying my 6.2 swap very much. One thing that is really starting to get on my nerves is the header "tinny/airflow" sound you hear constantly in the cabin. It wasn't as bad on my 5.3 because of the lower lift cam and smaller engine. But on the 6.2 it is starting to irk me...

    Torque converter - replace or let it be?

    Idle takes a lot of trial and error to dial in, even with negative overlap cams. I still tweak mine from time to time.

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    It's a marketing ploy. I knew it wasn't as good as OEM but I figured it would be better than this. My "professional" alternator is fine but I am replacing it after 2 years as well.

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Replaced the A/C delco "professional" water pump with a new OEM one. Water temps 20-25 degrees cooler... Never buying the professional line stuff again.

    6.2 swap thread

    Yup they're junk! I just data logged my truck and it doesn't go above 198 now. 20 degree difference. and it's 40 degrees hotter today. My oil pressure was also 3 PSI higher fully warm, I guess keeping things a lot cooler.

    6.2 swap thread

    New water pump is in but had a terrible scare. Thought I was good after filling up radiator and letting it idle so I went for a drive, the temp gauge immediately spiked to 260. I shut off the engine and coasted. I started it back up to see if maybe if it was just a giant air pocket and...

    6.2 swap thread

    Yeah for what it is, I'm pretty happy with it. Not sure how far I wanna take it, I always need more but there comes a point where "more" creates too many headaches. Yeah the ZL1 converter was a good budget choice, feels the same as the stock one. Gas mileage not affected too much either...

    6.2 swap thread

    It's funny how your brain plays tricks on you. I could have sworn the 5.3 "felt" about as fast from a 2nd gear roll. At the end of this video with the old setup, I do a little blip and it's crawling lol. It's not even close to the same.

    6.2 swap thread

    I timed this at 5.3 seconds. It is short shifting 1st a bit, I am losing about 400 RPMS. I raised my shift point and will do another test if I can. I know the LSXCalade guy got 5.6 0-60 stock stall with headers and stock cam, so this sounds about right. Be cool to hit 5.1 with a longer first...

    6.2 swap thread

    Took a 0-60 video and it came out terrible because of sun glare. If anyone has interest in seeing, I'll upload it. I'd take another one, but I always feel weird about stopping in the middle of a road to do a blast lol.

    6.2 swap thread

    So it peaked at 217 just now waiting for my son to get out of school. Low fan kicked on and it easily got back down to about 195 and didn't go higher than 205 from then. Seems erratic.

    6.2 swap thread

    I have the same setup as my 5.3. It's dual fan, oil cooler and trans cooler. It's running cooler after the overflow cap, but still seems higher than it should be in 45 degree weather. Seems to just be at idle though, so maybe it's normal. Cruising is 205-210. Idle will get up to 215-220...

    Gettin truck ready for a road trip to Williamsburg. Got some new brakes coming. I just went with the Centric premium with ceramic pads. Got all redline fluids for the diffs and transfer case as well. Pretty sure my transfer case has had the autotrac2 in it for like 50k miles, whoops. I'll...

    6.2 swap thread

    Specifically, all the ones that said New York were all terrible reviews. Stay away. I got mine from Montana. Other than some piston slap, it runs fine.
