hooker 1 3/4 or tsp 1 7/8 difference other than size more like hp gains?

 

You can get too big on primary size, unless you have the engine for the 1 7/8 you will be fine with the 1 3/4. On a stock engine You could possibly lose and I dont think you would see any increase IMO, Now ported heads and a fast intake with a stout cam and the larger ones are the way to go.

 

well i have a ms3 cam stage 2.5 heads 5.3. ls6 intake?

 

I have a H/C/I full weight Camaro Z28 with trickflow 215cnc heads and a custom Futral cam 1 3/4x3" Hooker long tubes with custom true duals and I've went 10.90@123mph on stock suspension.

 

Either of the two. There isnt much difference although people will tell you other wise based on what brand they have.
