Is there a difference between the Vortec manifolds on 4.8, 5.3, 6.0, etc..? Or. Are all Vortec manifolds the same?
5.3 vs 6.0 intake manifold?

They are interchangeable.
Just depends what year it is if its returnless or not.<----(not too sure)
there is no difference what so ever in the way they flow from 99-07...later models 07-current have a 90mm tb and flow a lot better
2006 silverado SS....Clifford Jr...turbo coming soon
1970 Chevelle ly6 swap....d1 coming soon
OK, thats what I was looking for. I just didn't know if the 6.0l flowed better than say the 5.3l.
mean05: You sayin there may be some potential increase in HP/TQ by swaaping to a 07+?
Thanks for the quick replies

i got port and polished stock heads, and switched to the TBSS 90mm intake and shaved over a half second on my 1/4 mile times, on motor.Originally Posted by stngh8r
maybe that'll help with your decision.

The difference between winning and losing, is having a 2nd stage.
the work done to the heads gave you the most of that gaini got port and polished stock heads, and switched to the TBSS 90mm intake and shaved over a half second on my 1/4 mile times, on motor.

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
For clarification: The ET change was with both listed mods or just the intake?i got port and polished stock heads, and switched to the TBSS 90mm intake and shaved over a half second on my 1/4 mile times, on motor.

his was both heads and intake...

1970 Chevelle ly6 swap....d1 coming soon
there is a small gain...some have said in the 10rwhp gain, i did the swap on my stock 6.0 and if i were to do it again i'd just go with a car intake...looks some much cleaner

Did you use your stock fuel rail or have to use one that came with the intake?
If your 05-rail worked the 99-03 rail should fit too.
