Steve - Shoot me another e-mail if you don't mind. I recently changed e-mail addresses, so it could've easily been lost when I switched.

Trev, I didn't know that you work @ LG now.
I just put in G5 cam last weekend. If I have time this sat, I'll drop by to dyno.
Lane, I went from B1 to G5 and with around 930rpm idle in gear, there is no stumbling or stalling @ stop light at all.

Sonny - sounds great! I'll be here 10:30-3:30 this Saturday, so come on by. I'm anxious to see how your car responds since your setup is pretty close to mine. BTW, I started here yesterday. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Lane - I'd definitely like to make it to the SLP day.

Trevor...I will prolly be ordering a new cam very soon. It's real hard deciding though. I am impressed with the results the LG cams have had. My new setup will be:
Stock bottom end (with ARP rod bolts, main studs), Stage 1 1998 LS1 heads (milled .050, stock size Manley stainless valves, Comp 918 springs, stock retainers, 7.35 pushrods), LS6 oil pump, LS1 edit (I own).
How much lift do you think I can get away with on these heads without fly cutting the pistons?
Which LG cam would you think would be optimal for mostly NA use, but future N2O duty as well (100-150 shots)?
I have been running a Comp 221/227 .561/.569 114LSA in my 9:1 motor. It's hard to tell if I would gain anything from changing cams, and the cam I have is prolly pretty good for N2O already. What is your opinion?
Thanks!

Great results Trevor! I can't believe that "Mean Green" dork in the vette forum moved your post. That guy is clueless when it comes to info sharing. He's doing the vette forum a disservice.

Todd - .050" is quite a bit, so I'm going to have to ask Lou and Louis when they get back in town next week. The norm around here for shaving heads is .020". I don't know how much p. to v. clearance there is with this cam, but I will find out for you. You have to look at the lift AND duration to see what you can get away with without any valve reliefs. We're not concerned w/ p. to v. clearance at the max lift; it's the lower lifts combined with the duration that become a concern.
Mean Green is a moron. I can see that we're not going to get along. <img border="0" alt="[fight]" title="" src="graemlins/gr_punch.gif" />

The G5 is just plain torquey. Look at Gary's graph. Peak numbers are one thing...but Lou being able to sqeeze a few ft-lbs in the meat of the rpm's is pretty cool.
The G5 would kick *** on N2O. Specs are 224/230 581/570 112. TR cam is 230/224 58x/56x 111.
Trevor....I would try the cam on a 110 or 114 just to test. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Ryan - I totally agree. Lou has always been big on squeezing out as much torque as possible. That should also add to the drivability fun. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> I don't want the 114 LSA because I don't need to be revving that high, and I'm apprehensive of the 110 LSA because it's going to CHUG. However, nothing is set in stone yet. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
Todd - Yeah, going back to the flat-tops will definitely make a difference. I'll get with Lou and Louis when they get back and get an answer for you. It's just good info to have anyways. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> I just might run a set of 5.3L heads so I can get my compression where I want it and not run into clearance issues.

im thinking you'd want to invest in a cutting tool to notch them pistons. the 224/581 side should be ok...JohnC's heads are milled like .060 i believe. the 230/570 is what you gotta worry about.

Guys,
Bear with me on the graph. I had the disk, but it mysteriously disappeared off of my desk. <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> I have another copy and will post it up tonight after I get home.

Just some off the subject questions. Why don't you guys like 110 LSA so much? I see alot of 112s, but never 110. Is it because of idle quality? If someone had a smaller duration would 110 be a good choice? Also IC is never mentioned. Doesn't that play a role above peak torque? And most of the time the cam is advanced. Is it "only" because of chain slack?
I love this cam dyno threads. Very informative. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

IC IS a good think to think about. On these generic single duration jobs is mainly to bring the peak down 2-300rpm and take care of the slack i guess. A G5 on a 114 with maybe 2 or 3 extra degrees advance ground in would likely peak were the 112 does...but LG wont let us know what it is. I think its 110-112, just guessing by looking at where is peaks. You'll see some 108 LSA cams by next year, especially with everyone going to solid rollers more and more.
