    LC9 swap from donor truck - do it?

    2011 with LC9 will have the 6L80E also. This would be a pretty fun swap, but your gonna need the Transfer case control module and all that to make it work right. IF you have a lowerish gear (3.73-4.10) this setup would be very fun and peppy with the 6L80 transmission

    Really wish ppl would stop bringing me trucks with hydraulic fluid in trans

    Talking to a buddy about this whole ATF/Hydraulic fluid deal. He rebuilt his ole TH350 about 12 years ago and used cheapest "303" hydraulic fluid he could find. Still running the same fluid today and he beats the crap out of it. SBC 383 with a 275 shot, 3800 converter, 3.08 gears in a 86 C10...

    Throttle Body Spacer

    I have always just used throttle body spacers as a way to run nitrous or water/meth injection on the LS engines.

    2006 Silverado Daily Driver

    I siliconed my 2003 tahoe sunroof closed just cause I never used it and was always in the mud so didn't want to chance pressure washer blowing thru the seal. But I do love the 800 trucks. I've got a few of them and don't like a single thing about any of the new trucks. So I'll be keeping my old...

    Weird question about a bypass filter

    I've thought about trying a bypass but not sure you will ever see a cost return. They claim it cleans the oil better and gives you longer oil life.

    6.0 turbo build advice

    that cam would be fine. Have made 1040rwhp with a smaller cam in a LQ4. Ive not seen the ebay log you mention so not sure how its made. Ive used KBRacing setups for 16 years then went to huron speed after Kyle passed away. Those T4 kits work great and depends on turbo size as to when your going...

    6.0 turbo build advice

    Me Love Turbo!! I turbo everything i can. Why stock PCM? Holley is substantially easier and has everything built in you need. I can set you up with a base tune and you can enjoy riding around. Walbro 450 wont flow enough fuel for 1000hp TSS? What size cam? Stage numbers are dumb. Summit rods...

    Its really not that bad. If you buy it just post your tune and we can help you get it atleast drivable again. I remote in to guys laptops a few times a day walking them through how to read the tune and save it. And tune holley ECUs all the time while the driver is out cruising around. And no...

    L92/t56 combo into my 1988 c1500

    https://cammotion.com/camshafts/titan-1-ls3-camshaft-217-225-114-2/ I vote this one unless you have a regular cab 2wd that is light. Ive used this one in LS3 Camaros with TR6060 and they weigh 4000#. Makes 475rwhp with CNC'd stock heads and 1-7/8" headers and stock LS3 car intake...

    Really wish ppl would stop bringing me trucks with hydraulic fluid in trans

    Ive used cheap "303" hydraulic fluid in a ton of TH400s and Powerglides. It works plus it can tighten up the torque converter some too. AW46 works good as well as the low vis John Deer Hyguard. Some of these 1600hp turbo trucks running 4L80's with a fixed pressure and transbrake last longer...

    5.3 clean dirty oil

    The first time i let it idle about a couple hours. The next time was about an hour. I used EFI Live to raise the idle to 1500rpms and just let it do its thing.

    5.3 clean dirty oil

    ATF cleans very good. When bought my wife her 08 tahoe it had the lifter tick. So i drained the oil and put 4 quarts of ATF in it. Let it idle for a couple hours at 1500 rpms. Drained all that mess out and put some cheap 15w40 in it and a new filter. When it was time to change the oil again i...

    Correct trans fluid?

    ATF Is backwards compatible so putting Dex 6 in is not a problem.

    5.3 clean dirty oil

    I'd get some cheap oil and a good filter (wix 51522 fits that truck) and just change it every couple thousand miles a few times and go back to a normal oil change interval

    Better gas mileage and performance.

    If the truck is all factory (intake and exhaust) The MAF and VE tables are based around that. So if its stock, you can remove the Oxygen Sesnors and the goes back into Open Loop which is VE and MAF without any fueling corrections. If the engine is healthy and all sesnors/injectors are in good...

    Better gas mileage and performance.

    S366/71's Yea I agree. I've got friends and customers that always want to build a 408/416/427 stroker and dump tons of money into them and then get out run by one these turbo 4.8 or 5.3 trucks and get mad haha

    Better gas mileage and performance.

    I've been spending a good bit of time tinkering with this twin turbo 4.8 in a '98 C1500 I did for a guy. With Th400 and 3.42 gears on 235/75/15s I got aggressive on timing and fueling at cruising rpms and last Saturday I took it for a trip to my buddys house. It was a 122 mile round trip. I...
