Default Longtubes w/stock intake or shortubes w/ LS6 intake

I have seen cam only cars put down 390 with short tubes.

After saying that heres the deal. I plan on doing a cam in the future. Not sure exactly when, but the day will come. I would kinda like to save some money, which is fine by me because im not looking to get MONSTER power. If that was the case i would do heads as well. My plan is a mild to decent cam and around a 100 shot. Like i said, i want to save some money, so what would give me more power....getting some longtubes with an ORY and keeping my stock LS1 intake, or buyin some cheap short tubes, and gutting the cats and getting an LS6 manifold. This way i could could ave money by not having to buy an ORY, and i know i could find a set of dirt cheap shorties.

It seems to me like having the shorties and the intake would benefit me more than just having the intake.

Lets say i did the shorties and intake, and decided to upgrade later to longtubes (which i really wouldnt absolutely have to unless i was going with something crazy). Would probably cost me around 400-500$.

Now if i went LTs now and waited to get the LS6, and then later upgraded to the ls6, it owuld cost me anywhere from 300-350 shipped. I would evently need the LS6...i cant see myself being too happy with numbers i would get with a cam and the stock LS1 manifold.


Anyways, sorry for the tangent. What are you opinions?

I would say go with the LT's now. Thats the order I did things when I did mine. I couldn't really see a point in changing the manifolds for something that wouldn't really make much more power. In my mind I wanted a big difference between what was there already and what I changed. Either way they are both things that a cam would need to be used to it's full potential so that's another reason I would choose putting LT's in now instead of shorties.

I'd do the Longtubes with the cam and LS1 intake. With a cam and tune the LTs should reap more HP than shorties with a cam, tune and LS6 intake. If you plan on doing both LTs and LS6 intake, wait until both are on if possible to get your tune. I know there is a cam in the mix, but it'd be nice to get it all done at once.

I went Longtubes first while running my LS1 intake. Then upgraded to the LS6 intake. That seems to be the route that most people take.

1st of all don't be cheap. Go LT's and try to pick up a LS6 intake. They can be had used for around $310-$350 shipped.

I would get LTs. They will have a bigger impact on hp. Save up for the used ls6. Then after you get a cam get a tune. That way you don't have to dish out $400 for a tune more than once (although re-tunes are cheaper...). Don't waste your time on shorties unless you are building a CA legal setup.

shorties are pointless. Get the LT's and use the LS1 intake.

Yea, another thing to remember is an engine is pretty much an air pump, the more air in and the faster it can push it out, the more power you will have. That being said I would def. go LT's to let the engine breath easier and if you can pick up a LS6 intake, but a cam is more pressure on an engine so you definitly want to free up the intake and exhaust. Another thing that will matter is what kinda cam your putting it, Im going with a hot cam so I dont think im goin to bother with aLS6 intake

i agree

i think you'll be able to get more from LTs than you will with shorties and LS6 intake manifold... LS1s LOVE longtubes!

yea technically shorties flow the same as LT's but the LT's do ALOT better job of exhaust scavenging then shorties do. In theory in you could rev our cars to 10K shorties would produce better gains higher in the RPM range, but since our cars are low reving cars they yeild little to no gain. To make it short and sweet header power has more to do with just how well they flow, theirs more factors such as scavenging that makes LT's have better gains

Alright guys i guess ill go with the headers. A 100-150 shot should hold me over till i can get the LS6...and later on the cam.


One more question. I put down 301 BONE STOCK. Stock lid/filter/exhaust, everything. If i were to put the LS6 intake on right now, i should gain some RWHP correct? Advertises 15rwhp, i know thats not a set in stone thing becaues it varies with every car.

Just save for however long you have too to get Lontubes and the LS6 intake. A mid/large cam and nitrous will need the longtubes.....and the intake will make a big difference over the stock LS1. Don't cut corners, especially corners that are easily "driven around"
