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?

99 C5 cam/boltons 400rwhp

03 Suburban 5.3
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

Will the 99-03 return style fuel rail fit on the 07+ 5.3L intake?
There is potential, but it is going to be minimal. I would rather spend my time and money on a FAST setup...Originally Posted by stngh8r
I wouldn't think so. I am not sure if anyone has tried to do that type of swap, but it may be possible.

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.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
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

1970 Chevelle ly6 swap....d1 coming soon
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.
