Quick update. Been chatting with techs while ordering parts. Trying to make sure I cover everything I need so I can add the fun parts and not blow it up. I am hoping to see 120k before I dive in to doing a full rebuild

Mighty Mouse "insane" catch can setup.

I did this cause if I ever do heads and cam or forge the bottom end, I didn't want to have to get a replacement catch can.​

Whipple 2.9 stock setup (8lbs boost)

Everyone I talked to said stay under 10lbs or other "stuff" is going to be needed (Think trans input spline, valve train, etc)​

Circle D 3000 stall speed converter; 3 disk lockup

A pro transmission tech suggested I get a 3000 stall. Circle D recommended a 3 disk lockup. Good for the power band from a dig and will slip less at highway speeds.​

Bypass valve on the 6L80 trans

The same trans tech says to install a bypass valve in the trans so it will open up the flow. 6L80 opens at 194 degrees and that is on the high end of the temp. Keeping the trans temps down will increase longevity although you will need a few more minutes in the winter for the trans to warm up and shift properly.​

Aluminum Driveshaft from driveshaftspecialist.com

5" diameter 1 piece, adds strength, reduces weight, wont explode over 100mph​

Glowshift Illuminated Boost guage and single pod

I may order a tach with a shift light and return the single pod and get a triple. I saw diff temp gauge which I thought was pretty cool even though unnecessary.​

Wilwood BBK

These are a long time coming cause I think the brakes on these trucks are for shit.​

I hope I got everything I need.

I'm holding off on a set of gears for the time being just to see where the truck is at with he added power. I'm running 3.08s which is super tall but my rpms are under 2k at 80mph which is normally where the cruise control is set on the highway.

yes... only 5.3 was avail in tahoe/burb.... until like '18 w/ the RST pkg

factory airbox will support your HP on stock pulley (6#) you can then add a better drop in filter.

or i went w/ the GM performance CAI. this way GM wouldnt be likely to void my warranty


i love my Corsa exhaust & i dont even have LTs yet

a single 3" exhaust can handle 500-600HP.
the 6.2 models have 3.5" exhaust & those seem to handle 700-800, just fine

if you have a 5.3 w/ a 2300... you lose some low end TQ, but gain more HP on top end, compared to me.




1st time on dyno w/ callaway/magnuson tune, i had 403HP/400TQ
after BBP tune, i had 430HP
i havent been back since i did GM CAI & smaller pulley... in theory i should be in 445-465 range

i have LTs ordered finally. just need to get a new driveshaft, before i do next dyno run.
w/ LTs, an updated BBP tune, new plugs & wires... hope to be in the 500-520 range




eta:
definitely remove airbox & trim fender opening... you will see what im talking about
then port the box opening to match the fender opening.
that will help a little too

pretty sure someone has a thread on it here

Hola! Thanks for the suggestion, I have a question: I live in an area with constant flooding ! So what should i do then?i have never had water top the hood line but you never know. What should I do? Thanks!

thats a tough one... prolly not a good idea to open up the inner fender just in case
also prolly not a good idea to lower your ride LOL

id leave stock airbox as-is. it supposed to support up to 600ish HP w/ free flow filter swap.
if water is getting that high... you may want to look & see if a snorkel kit is avail (although that would require cutting a hole in your fender for install)
