cam question
 

I want to install a new cam for alittle more hp. Would new heads and rods ect. really be needed? The only mods I really have is a SLP lid, GMMG cat back, Pacesetter LT's, and a TSP catted Y, (working on getting a SLP LS6 intake). And what size cam would you recommend for my '98 Z?

Re: cam question
 

heads are not needed at all. the stock casting flow pretty freakin well. you'll make more hp if you did heads...but it will still run fine after a good tune.

i suggest a TR224 cam or so

nothing really special is needed other than valve springs, should net you around 370-390hp after a tune (with your mods maybe more) and will be streetable

Re: cam question
 

youll need PRs,springs,retainers ect with most cams.


what you need is usually available with the cam your buying.


TR cams seem to make nice power with stock heads.

I was looking at the TR224 cam, but ive also been looking at the comp XER cam , it has 224/230 duration and .581/.588 lift. Does anyone here have that cam, and which one would make more power? I know Thunderracing has awesome custom grind cam, so is there any reason to believe the TR224 would make more power then the XER cam?

Re: cam question
 

Higher lift usually translates to more power, but it also has a lot to do with other bolt-ons and the tune of the car.

Ok, so how does this package from Thunder Racing sound:

CamPk-S = 224/224-114
26918 valve springs
reuse stock retainers
TR stock length pushrods (7.400)
new gaskets

Seems to be in a good price range. But I am confused by the cam size. There was a 224/224-114 and a 224/224-112 :confused: I really don't know much about cams. My goal is to reach alittle over 400hp. Tell me what you think about this package, I saw it on ThunderRacing
