Ok which one will give more power??

Cam 1:
218/230 .525/.542 112 lsa

Cam 2:
204/218 .551/.547 117 lsa (ls6 cam)

 

current mods on truck? Which engine?
A 224/224 is a proven cam with great results. I have the Comp LsR 227/235 in my 6.0L and I gained about 60HP with just the head/cam swap.

 

Gonna need more info about what the cam is going in and supporting modifications....... What are you wanting to do with the truck?

 

Oh sorry guy, going in a 2004 rcsb 5.3. K&n intake, longtube headers, ORY pipe, magnaflow exhaust, efans, vette servo, ported tb.

Will be installing a trailblazer ss intake with the swap. I plan on spraying as well

 

Stock Torque converter? If so I would suggest a 212/218 low lift from comp

 

Sticking with stock converter.. which of the cams above would be best?

 

I would stick with the ZO6 cam.

 

I just don't think you would be happy with a z06 cam IMO.

A comp 212/218 low lift or a vinci 210/218 would be a worthy upgrade.

You can get by with stock converter with those cams, but don't go any higher than those IMO. Later on all you would really need is a tame 278mm converter from FTI or Circle D and you would be happy. Also maybe install a bigger tranny cooler.

FTI 278mm converter ranges from $329-$349.

Circle D 278mm is $375 with promo code.

 

He didn't ask about another cam...... He is asking about the 2 he posted.
