i know our intake manifold are the same as TBSS , and they seem to flow pretty good. 'bad thing these things cant be taken apart for porting, unlike
ls2 intake (3 piece) way ligher Porting capable. these are all based on gen IV so im pretty sure the swap is pretty straight foward, has any-b done this swap.... any imput?

 

doesnt FAST make a bolt intake for our trucks ?

 

Ya if you feel like closing out your bank accounts to pay for one.



to the OP The stock intakes flow fine but I see what you mean bout taking the other intake apart. I would just try and port the stock one. Gonna be a little bit more of a challenge but it flows just fine.

What are you plans? Why do you need to port it.

 

..since the ls2 intake can be taken apart (3piece) there's more room for improvement.. since my heads are getting ported all the way, Don't know if you all have noticed the intake catheral port on the intake is slight smaller than the intake catheral on the head... so im gonna match port my intake to my head's it should make a nice combo. with some 4XX mark numbers... so i'll let you all know on the swap.. since i haven't seen this swap on NNBS...
