So I have an 05 base model ext 4.8 Silverado, and I知 looking at cams. But I want a cam that痴 good for daily driving but also gives the truck good power gain. I知 looking at a TSP cam that says (new to this still) duration .050, intake 222 exhaust 222, lobe lift .353/.353, valve lift @1.7 .600/.600, lobe separation 112, intake center line 108, is this a good daily? If not what are good choices for what I知 looking for

 

4.8L in an extended cab truck, you are looking too big. I assume from your specs that you're open to a spring and some form of rocker trunion upgrade?

Either way, on a 4.8 you will probably be best off with something sub 210 intake duration like most stage 1 cams. Otherwise you'll be shifting your powerband above normal truck operating speeds. Texas speed sells a stage 1 low lift truck cam that would be fine but so do several companies.

 

What compression ratio? What rear gear and tire? Torque convertor stall?

 

Stock 4.8 is 9 CR. I'm assuming he has 3.23s and stock stall lol

No offence OP but those are the vibes your post gives off

 

We agree with others. This seems to be swinging for too much. Something we'd look at for a truck with a stock 4.8 would be our Pro LS Truck stage 1 high-lift cam. That's part number SUM-8719R1. Specs on it are .550/.550, 209/217, 112+1 with -10* of overlap. Pair that with some budget-friendly LS6 springs and it'll be happy to 6,500+. That will work just fine with stock gearing and converter.

This is also available in a combo with items to help with the cam swap. That would be part number SUM-8719-2-BHV. This gets you the cam, springs, valve seals, harmonic balancer bolt, and a cam change gasket set.

 

or smaller cam with 525 lift the 4.8 dotn responed to cams as well as larger motors..
get a blower! now those things work

 

BTR GEN III & IV TRUCK CAM - TORQUE - 30202111R1

Pretty sure you don't have to change springs or pushrods. I would also get speed engineering long tube headers and y pipe. This would add power from idle to 6000.
