Suggestions on Cam.... Current mods are in signature.
Car is a road race/street car and don't want to have to spin engine up to 7,000 to make HP. I would really like a power band between 2,000 and 6,500 RPM. I WANT a rough idle!!! (BLAP BLAP BLAP BLAP = VERY GOOD ). When I get the money(max of 6 months), I am thinking of doing a stage 2 port/polish on a set of 5.3 Liter head to boost compression some. I'll have the valves increased to the size one above what the stock 5.7 Liter heads have.
Have been looking at using the Thunder Racing 230/224 .569/.563 111 Cam. What do you people think of this cam for what I have stated above?
Thanks,
Chris

Re: Suggestions on Cam.... I went with the TR224/224 109 with a 2 degree advance in timing, my car lopes so hard, i can sit a coke on the hood and it just vibrates off. I just installed it today, and im amazed. It lopes so damn hard.

Re: Suggestions on Cam.... I heard a 226/234 on a 112 and 4 degrees of advance this week and it loped HARD. Best sounding cam I've heard so far in an LS1. Anyone here have that cam that has a soundclip? It makes good mid-range power and torque. There's bigger ones out there though.

Re: Suggestions on Cam.... Our G5 cam has a power peak at 6400rpms and a peak torque at 4400 +/- Our best cam and head numbers were 438rwhp and 424rwtq. I would say , and I have said before, that this would be the best all around cam. It has a lope at idle, but we have no problems with the idle, it pulls like a stump puller, and makes up in the middle more than the couple of hp it lacks in the last 200rpms. If you drive between 6700 and 6900, then there are a couple of other cams you should look at. We can supply you with any grind that you want, so give us a call.
I know that there will be plenty of opinions, but if you are going to road race the car, you will want the mid range torque more than anything.
Just to reiterate, we can supply any of you with any grind that you would like, and we will match any price. Thanks.

Re: Suggestions on Cam.... Lou,
I checked your site for the G5 cam. It says it has a 112 LSA. Would it be possible/advisable to get a little tighter LSA? As I said I want a good BLAP BLAP out of the cam at idle.

Re: Suggestions on Cam.... Lou,
Also.....would it be possible to get the durration and lift on the cam? Don't mean to sound like I'm trying to get your secrets....would just like to be able to compare and see what I'm getting.

Re: Suggestions on Cam.... Tell me again what the advantage for wide/narrow LSA?
I know wide (ex: 116) idles smooth and narrow (ex: 108) is harsh....but how does it affect the power band and overall hp/tourqe?

Re: Suggestions on Cam.... The narrow LSA will give you a little more power, at the expense of off-idle response. It may fall off in power slightly more quickly after it reaches its peak.

Re: Suggestions on Cam.... I would choose cam with higher lift when looking at bigger(224*+) duration. It is not that hard on springs to have near .600" lift if its on a lobe with bigger duration, the bigger duration design gives more cushion for opening/closing ramps so contact shock is dispersed, at least when compared to a same lift but smaller duration design cam. High lift is a great thing for power cause it doesnt soften low speed torque the way duration does, its a win win situation to have more lift, provided you can maintain reliability with proper springs etc. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Suggestions on Cam.... ok.....its getting close to ordering time. I am going to call TR and LG tomorrow and talk to them about their cams.
I need another piece of info. My heads are 5.7 Liters milled 0.035. Anyone care to suggest how much lift/duration I can use with these heads before I smack the pistons. I am not going to fly cut the pistons or anything like that (the cam needs to work with the stock short block).
Thanks for all the help thus far.

This process does two things:
1) removes any "warpage" the gasket surface has gained over the years (usully only 0.001 or 0.002...very minor)
2) if more is taken off (ex: my removing 0.035), it makes the combustion chamber smaller, thus raising the compression ratio.
any questions? <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />
