I want to put a better cam in my Ls1 when I do the swap, but I don't know what are good cams to go for, any suggestions? what other mods are required if any? thanks

 

depends on how big of a cam you want to go, but bolt-ons are usualy a must. That and gears are always helpfull, as for a cam, i would contact Futral Motorsports they seem to be making the most power with there cams. Swing over to ls1tech.com there is tons of information on cams over there.

With any cam swap EMC reprogramming will need to be done to make the most of the cam. Competent OBDII tuners are everywhere nowadays and a good dyno tune should be set-up as soon as the car can drive itself there.

Check out the followng sites to help pick a cam for your LS1. You have many choices and can go from wild to insanly wild.

www.ls1tech.com (best Gen III motor site on the net)

I think he meant MILD to insanely wild.

A couple more good sites are:

www.ls1racer.com
www.ls2.com

Cam selection is going to be a hugely personal decision. There are going to be a LOT of factors that you have to decide on in order to select the "right" cam for both your own personal tastes, driving habits, and the build-up of your car.

 

ls1tech has some really good info. i ended up with a TSP setup, which i think will work really good for my car. i went with one of the biggest cams you can fit with stock pistons. do a search on one of the sites listed above, and im sure you can find the perfect cam for you and your car

 

I meant wild to insanely wild as a pun.

It was a play on words based on the fact that even the mildest of cam swaps in an LS1 make monster power gains. Being as such, I was reluctant to classify a 400hp motor as mild. It was a humerous attempt at getting him excited for the great results any Gen III cam swap brings.

 

Then I stand corrected.

 

From my lack of cam knowledge, that doesn't mean a whole lot to me. are you saying a large part of that 400hp is from your cam choice? How much are you actually talking about? what kind of "bolt ons" would be required (I am looking into the 6.0 truck/SUV head swap)?This car will end up being a daily drive, but I would like to be able to step on it and definitely impress all those in the area (and leave quite an impression on the pavement as well ). Do these sites like ls1tech.com give suggestions based more than just on technical jargon, because I don't completely understand how cams work? Does anyone have personal suggestions?

 

The right cam can unlock huge power in an LS1. There are some LS1's running low 11's and high 10's with cam and tuning alone. Stock short block, stock heads.

 

A stock LS1 with headers will make almost 400hp on an engine dyno. Most 6 speed cars put down near 350hp to the rear wheels with long tube headers and a full exhaust. You can see how much power you have from the get go before you even touch the guts of the motor. Some guys want to do a cam swap but want their car to perform closely to stock as possible as to trick the GM techs when they get their car serviced. Some go with an LS6 cam which is only a little bit bigger than the stocker. Those people end up putting down 360 to 380hp at the wheels which is a solid 420+ at the crank. So even a cam that is margonaly bigger than stock will push you beyond the 340 to 350 rwhp mark. With gains like that it is hard to call these motors mild. They are mild in the sense of drivabilty, fuel mileage, and idle quality but they are nothing short of monsters when you look at the power numbers. Its sorta like having your cake and eating it to with modern fuel injection. It is so exciting to mods these motors when you know you are already starting out with gobs of power and potential. Now if you have extensive head port work and you add a much larger cam 400+hp at the wheels is very doable.

You really want to have a full exhaust before you consider any cam swap. The stock exhuast it a great shorty design but it still limits the motor tremendously when compaired to long tubes. I would look at some of those sites and see what times people run based on their mods. Don't be afraid to ask people questions about their cars and how they like the cam they chose. It all boils down to what type of idle you want along with how much streetable or non-streetable power you really want.
