Swapping a cam for a friend
2000 chevy ext cab 4x4
5.3 stock
35" tires
3.73 gears
He wants more low end-mid range he does quite a bit of off roadin and towing
Any good suggestions?
Thanks in advance

 

Something below 220 on the duration..a 212/218 low lift would do great..and swap out the 3.73s for 4.56s

 

Suggestion for more low end power? Gears. 4.56 at least. Those big tires and 3.73 are killing it down low. No cam will help much below 3000rpm. 212/218 is a decent option.

 

Longtubes will help too, dont forget to have a good tune to go along with it all

 

I would say before the cam that you do long tubes and gears. And of course tune it. Then see if you still want more.

 

He will always want more... Thats just how it goes!...lol

 

Well he says no to the gear change i told him at least 4.10s would help turn the tires better but hes dead set on cam swap i told him what the ls6 cam did to my 4.8 before i boosted( draggin a lead sled till bout 3krpm)but he still wants it...

 

Even after the cam swap its still gonna feel a little bit sluggish on the bottom end with 3.73s..a 2600-2800 stall converter will help, but some 4.56 or 4.88 gears would make it a completely different truck..he does understand a 3.73 isnt ideal for towing right?

 

Long tubes and mill heads to increase compression. A Cam Motion cam would be a good choice because they focus on streetable midrange power.

 

why no to gears? that will give him his best bang for his buck for what he wants. it will also save his trans.
