Besides selling my truck or doing an engine swap
What can I do to make my truck pull down low and up top to run like a bigger cubed motor?
Don't really want to spend the money to do a head swap

The only thing I have done is a 3" dynomax catback

Thanks

 

you can race with hopes and dreams lol.

your not going to make a 5.3 run like a 6.2 unless you do some serious bolt-ons. even then you might not be quite there...

 

Forced induction.

 

no replacement for displacement

 

As said above, I think F/I is the only way ur going to make a 5.3 run like a 6.2

 

dude is already saying he doesnt want to pay for a head swap, im sure FI is def out of his budget lol

 

Yah, unless you plan to dump alot of money, the 5.3 isn't going to have the low end grunt like a 6.2

 

True, well his goal is unrealistic then IMO. It's either h/c/I or fi

 

no offense but if you dont want to spend $1500 on a head swap this hobby isnt for you.
This hobby is expensive and never stops.

 

TVS 1900 or 2300, good flowing heads and blower cam along with all the bolt ins should do it well.
