Performance upgrade Ideas for my 2001 5.3 Tahoe

[Evildmanarc]

I kind of like that ram air hood. If you're gonna do any engine upgrades, you'd better budget a trans upgrade too. It's the weak point. My trans blew the 1st time I raced someone.

I'm honestly thinking of putting a big Ole middle finger to the 4l60e and doing the 4l80e swap and my buddy at work is talking me into it. Junkyard 4l80e with the 1600$ conversion kit from https://transmissioncenter.net/shop/4l60e-to-4l80e-conversion-kit-tahoe-hummer-2-pickup-others/
Would be the same cost as buying a beefed up 4l60e.

The BTR is made for a truck. Hence the “Truck Cam” portion of the title.
Thanks

Am I on the right track? That's VERY affordable too.

Yessir

Nope lol but if I ever plan on doing any more performance upgrades going over 700tq/hp I might as well go ahead and swap it out lol

Do you think that cam will rob the low end ? I love my low end I was hoping to maybe even give it more with a cam. If you have a good reccomendation that would be nice. I was just thinking a nice drop in cam to keep the driveability yet still gain some power

Sure do, it's ground for a car, not a truck. BTR, Cam Motion, Vinci and the old Crane Cams had good truck grinds with less than 210 degrees duration. Hot Rod tested the Crane Cams and they were the only ones (the others mentioned were not in that test but others)(look up Hot Rod Crane Cam Trio) to not lose torque down low.

Crane 1449541. My own preference is for the more mild 1449501 but am in the minority here. Most fellas here who have actually swapped cams opt for much larger ones. Some however, have regretted going so large, others compensated with high stall torque converters and or lower gears and are happy as a clam.

Crane Cams Direct fit Cams for LS Stock OE Valve Trains 4.8L to 6L

Crane Cams has specifically designed direct fit cams for 4.8 6.0L LS Series engines to maximize power while utilizing stock valve train, without exceeding the travel of a stock valve spring. The goal was to maintain near stock idle characteristics, v

You can piece that kit together for quite a bit cheaper on your own. Plus the wiring is super simple to do on your own instead of adding in the pigtail there. You just need to swap 2 pins at the connect of the transmission, then add a second speed sensor (plugs into connector at the ecu and then drop it down to the trans), and then have someone 4l80 segment swap your current tune (gonna want a tune either way so this is free).

Watch some Richard holdener videos, he’s recently done cam testing for exactly what people here want, more torque.
I think the sloppy stage 2 cam still seems like the best bang for the buck.

That is why it is called "Cubic Dollars". Or at least when I was younger it was. For all I know it may be called, "I want it and I want it now!"

I will have to look into that then. I definitely want them to modify my crossmember, as I don't trust myself THAT much with a welder. Thank you for your input!
