I'm new to the ls game and I'm having my 2nd one built. I'm trying to learn how to do it myself. If anyone can help, it would be much appreciated! My funds are limited at this moment also. My 1st problem is deciding on a cam to run in a 2005 ls stock 5.3 lm7. I found a great deal at BTR but I can't figure out which stage cam to get. The guy helping me said to get a low rpm cam but I can't find the ranges anywhere. I want a good/big cam but I'm not for sure if I can do a stage III or stage IV...please help! I already have headers and full exhaust.

 

A lot depends on the vehicle. For example, if it's going into a suburban and will do a lot of towing, that's one thing. If it's going into a Datsun 280z, that's completely different. You want high revving power or low end grunt?

 

It's going in a 86 C10 2wd with 3.73 gears I believe. Shackled in the rear with 275s on 20s.

stage 3 should be about right then. You might also want to look into a higher stall converter if showing off is your main goal. Higher stall allows for more cam, but if you're not doing much other work, S3 is as big as I'd recommend.

 

Much appreciated guys!
