is the twin 58mm TB the biggest for the LT1? can yall recommend what i should go with when upgrading this part? are air foils needed on aftermarket TB'S?


here's what i currently installed if it helps yall picking out the best TB:

pacesetter longtubes
ORY
SLP loudmouth

 

Your stock throttle body is enough for your current mods, waste of money for little to no gain at this point.

Stick the money in gears or something along those lines.

 

sorry, along with the TB, i was wanting to add the following:

SLP CAI
Trick Flow Intake Elbow

would you recommend the TB only when i start getting ready for a heads/cam upgrade?

 

correct!

 

If the twin 58mm TB isn't big enough, there's a "monoblade" that's even larger. A 52mm will take you to 500 flywheel HP, based on my dyno testing. Listen to Javier.
