How's it going everyone I'm new to this forum. I just bought a 09 Chevy Tahoe ppv 5.3 vortec that has a TSP chopacabra cam in it. I'm looking to add more HP to it trying to figure out what type of headers I should get for more gains. Also looking to do the plugs and wires any help would be greatly appreciated
I’ve had great luck with my speed engineering Longtubes I have their 1 7/8” with the full 3” exhaust x pipe duel corsas to 7” axle dumps and it sounds great and really helped out in power especially after the tune. I’ve never seen the benefits of all the money for a nice intake I’ve personally had decent gains by doing nothing but home porting the stock throttle body and intake
I also took the stock 243 heads and had them ported and milled down a hair with new springs retainers and a valve job and the truck just ripped to be on a 9” lift and 37s it would just get down even with the stock 3.73 gears in her
It was a basic build
5.3 with the ported and worked 243 heads
Ls7 beehive springs with titanium retainers
Valve Job and milled the heads
Bigger hardened tsp pushrods
All new gaskets
1 7/8” Longtubes full 3” exhaust no cats
K&n cold air intake
And a bad ass tune
The next step for more umph is gears it’s the best bang for your buck imo
Nothing but Longtubes and exhaust with some gears and a bad ass tune and you would have a pretty stout machine
