Well i decided to go with heads and Cam over Nitruos!... but the thing is i no nothin about heads or cams.. could i got some recomedations here.. brands, costs, and specs... thanx... i wana get the heads and cam at the same time so what would be the perfect match.. money's and how much power should i expect with this change? where will i get the power?? most likely higher RPM's?? thanx for any help or advice.

 

First of all, you need to define what you want the car to do. For instance, if all you care about is big peak numbers, that will mean a different setup than if you're concerned about power across the entire rev range.

There are multiple combinations out there now that seem to be turning out decent numbers... in an M6 car with other bolt-ons (headers, lid, etc...), there is no reason that you shouldn't be able to lay down 410+ RWHP and anywhere between 390 and 420 RWTQ.

The Thunder 224 cam matched with either GTP or JPR heads seems to make a real stout combination. Of course, being Canadian, you may prefer to go with something from ARE- you honestly can't go wrong there. The setup I am going with, though, is the LGM G5. That cam coupled with their heads seems to be making some really nice power. In addition to that, they are local to me; so I am comfortable with Lou and the rest of the LGM folks.

All of that being said, though, you need to decide what your intended use for the car is, and go from there.

 

As stated above, what are your intentions for the car, as well as budget?

 

There are some excellent sites out there that explain most all of what and how a camshaft works & how the various #'s affect performance characteristics.

I know this is a big download, but it's well worth it to download & print the minigide: http://www.motionsoftware.com/minigide.htm The minigide has excellent info (IMO) about the various components of an engine and how they affect each other.

Comp is another site that has info on valve timing: http://www.compcams.com/information/tutorials/

Also, several fellers have actually posted what their experiences have been w/ their respective cam choices (and mods): http://ls1info.com/camstats/showdata.php The main site: http://ls1info.com/ also has numerous articles and reviews about sundry parts of the LS1 powered vehicles.

And recently, CHP (Chevy High Performance mag) had their annual camshaft issue. If ya hitcher local library, they *might* have the last several years worth of issues. CHP does a good job of explaining all about cams.

 

check the other post about H/C combos everyone is listing combo and #'s good info in there.

 

Thanx for the miniguild.. its down loading right now.. i'll have to read it and see what i can do. Ya i have done a little search for other peoples set ups.. but once again im in canada.. most of theses set ups are US only parts.

 

Thanx for the reply, ya use canadains are limited to our parts.. the US is always a couple years ahead. My intentions are to try to get power all thro the RPM like u stated.. right now i'm not to worried about money. i got one quesition.. do u no if edelbrock is any good?? i can get there parts no problem.. same with holley, comp cams.. if your heard of those? proboly have. and also i was thinkin about 202in 160ex heads.. but not sure exaclty what they would do for power and so on.. so mainly i want power from at least 2000RPM and up.. hope this helps u help me <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I'm looking at the JPR S2 heads, they can't be beat for the price. TR224 112 cam or the Hammer1 or 2 cam.
