I am ready to order the crower cams for a ls which do u reccomend


the 403 or the 404 and if u have any experience with either of them give me your thoughts.

 

is this for turbo?

 

Everybody this is for a turbo ls (I thought i was in the FI forums)

 

I would go with the 403s unless you are planning on racing often. In that case go with the 404s. They will have a shitty idle if you dont have a standalone or some sort of fuel controller.

 

Didn't u have the 403's if u did was a big diff?

 

Yeah i had the 403s but i sold them to 97blackteg. I had some more headwork done and i am moving up to the bigger cams.

 

What about 404s and nitrous? Anybody running those cams with nitrous?

 

They will probably work well. Nitrous likes high compression and big cams.

 

Hey what are the specs on your turbo i have a gen II do u know the specs on that turbo 94 ls

 

the 404's will definatly give you more power. i just put 404's on my b20 block w/+4 on the intake cam gear and -2 on the exhaust. i had to bump idle up to around 800 for it not to stall out. they're nice.

 

Hey guy whats the setup turbo is it. have u had it dynoed yet?

 

I just got off the phone with Brian out at Crower. He says the best cams to run on a turbo application are the stage 2t. For an ls the part number is 62402-$401 and the springs/retainers kit is 84162-$326. You can go with the different stages, but they make a turbo grind for a reason. Just my .02.

 

Brian insists that but owning nearly every Crower came xcept for the 62405 there are far better choices for LS turbo owners.
