Yes I am a newbie but I have spent countless hours searching and I still need help The amount of info and choices out there are overwhelming! I am not trying to be lazy but I would really appreciate some feedback from knowledgeable people as to which parts would be best to acheive my goals. My plan is to add heads, cam, LS6 intake, etc to the stock LS1 bottom end. Here is what I would like:

-400 to 425rwhp. The more the better
-Good power to 7000rpm. I want a bit of a revver!
-Good idle, although I know it won't be as smooth as stock.
-The most reliability and least maintenace possible!

Obviously I will buy some nice heads and a cam, but do I also need lifters, springs and different rockers? I have read about people breaking valve springs every 10k miles and this would **** me off! Can I have factory reliability and 425rwhp?

Lastly can you please suggest some good parts for me to look at ( I don't need help with exhaust). With more than dozens of choices out there (Cartek, MTI, Patriot, LG, Comp, Crane, ...) it is very hard to know where to start. I don't mind paying a bit extra to get the best but I don't need a "name brand" for bragging rights

Thanks

I would suggest a F13 cam and some Ported LS1 heads. I made 421hp in a automatic. If you are a Six speed you are probally looking at quite a bit more. This cam is not a HUGE cam that will destroy springs. I think you would like the set up.

Thanks for the advice. Who makes the F13 cam? Are you saying to just get the stock LS1 heads ported by any of the known shops out there? What about all the fancy Stage1,2,3,C5R stuff I see advertised?

Thanks Terry, you've got some impressive #s there! I don't know anything about the PRC heads, where can I find out more about them? What cam would you run to meet my goals?

From searching around the AFR 205cc LS1 Mongoose Street Head looks good but I know making power is more than specs on paper! Any comments?

Search button. I know you said you've been researching, but with the questions you asked....its obvious there's a lot more you can do. There are more threads out there concerning head/cam packages/combos on this board then you would want to bother counting. Everybody will offer you different opinions. gotta read, newbie

425 can be achieved with reliability, it just won't necessarily be as reliable as stock. obviously any cam with more extreme ramp rates will wear springs faster. go with dual springs and even if one snaps, you should be ok til you get her shut down and replaced.

Everyone will be partial to their own preference. Figure out your budget, narrow it down a little, and start digging into the details. Thats usually where you are going to find the big differences that will make or break a decision where you spend this much money.

i hit 435rwhp with my setup

We have set ups from 420 rwhp sleepers to 502rwhp (pump gas) window shakers...

Futral Makes the came. My head are about a stage 2 head. So you would easily put down 425 with any heads.

I just read over the LS2.com "cam guide" and took in lots of good info. It seems like a standard 224 114 type cam would be good for me, as long as they make power to 6500+rpm. Am I on the right track? I know I stated that I want 400-425rwhp but I don't just want a peaky motor with no mid-range!

Heads still confuse me a bit. The Patriot Stage II @ $1395 looks great. What more do I get for spending $2395 on the AFR 205cc Mongoose heads? That extra $1000 would cover the cost of a cam, gaskets, new chain, oil pump and more! Is there really a big gain in power for the big dollar heads?

you read my guide huh . you can hit 400rwhp+ with a 224 grind, a good pair of heads and bolt ons.

i suggest you do your research on Patriot and come up with your own conclusion. I'll say you get what you pay for and leave it at that.

below is a members graph of three cams w/ stock heads and bolt ons:

tr224 112 - green
FM 13 230/232 112 - red
g5x2 232/240 112 - blue

Hey jrp, yes I read your cam page and loved the info in it! Great work!

I can read between the lines about what you are getting at with the Patriot heads, but I can't find too much bad about them. Can you give me a bit stringer hint as to why they are sooooo much cheaper that the AFRs and others? In terms of real world day to day use what will I not get with the Patriots? Keep in mind my goal of 425rwhp with bolt ones, not looking for a monster motor.

Thanks

I know this post is a little old, but did anyone notice the A/F ratio on the above 3 cams? Does 14.2 seem high to anyone or a little 2 lean to get those numbers? I was tuned to 12.8 and my numbers were about 385 with heads for a 224 cam FWIW.

I would not run my engine WOT with those AF ratio's but even though they are lean they still are making great power. Although you must ask at how much risk to the motor. My car is 12.8-1 at WOT from 2500-6800rpms and I make the numbers in sig thru cats so that proves there is nothing wrong with a 12.8-1 AFR. On the street it will read a few points higher than 12.8-1 actually.

I'd say a 230ish cam with a higher LSA, decent Stage II heads and the supporting hardware should get you where you want to be. Just figure out what you want the car to do before you pick the parts. There are a lot of ways to hit 420rwhp, but some may not fit your gameplan.
