No speculation on my part. My reply was accurate as of ~two months ago based on a discussion with Ed @ LPE. I made two calls to LPE about this cam and it's application. I also inquired about the other cam too.

This was ~2 to 3 months ago. Maybe things changed in the last few months.

I called LPE on two occassions to discuss this cam. Ed mentioned using the 918's to me with the blue stripe to me on the phone when I called and asked about this cam. At the time he indicated 918 springs were used in some of their applications without issue. I also asked about ramp rate for the GT2-3 and got a vague answer. I asked for more specific details ie is it about as fast as an XE? He said he'd email the reply and never replied. I called back for follow up ~two weeks later and got an evasive answer again a promise an email would be sent with a reply. Ed said he didn't know if the GT2-3 ramp rates were fast or slower or about the same as an XE. I was told the engineers might be willing to answer the question but they were really busy. He also told me to call up Comp Cams and ask about the ramp rate if I really wanted to know that bad. I pointed out I would expect that LPE had this cam as propiarary grind and I suspected Comp wouldn't discuss it. He agreed. I came away from the discussion with two impressions:

1. The GT2-3 was a good cam but being hurt by a lack of good information about it.

2. Selling cams to guys with F-bodies wasn't something LPE wanted to waste much time on.

I didn't get reply from Ed after the second call regarding ramp rate so I guess that was my answer. I bought a LPE GT2-3 from another board member so I can answer my own question about ramp rate for the GT2-3

That would make it very close to Comp Cam 216/220, .525/.532 114 lsa with 1.85 rockers, but less lopey, more docile.

I think the GT2-3 ramp rates are much faster than the Comp 216/220. The GT2-3 's 220 exhaust lobe with .580 lift might be or similar to an XE-R lobe. Likewise with .575 lift on 207 intake I would expect the GT2-3 to have a much faster intake event. All this plus 118.5 LSA means the GT2-3 should be more docile than the 216/220 as mentioned above.

That's fine...speculation was intended to the general public questioning what goes with what. Tim - the sales manager at LPE - is the one who sold me my package and had given me (although didn't disclose everything) the info I had mentioned earlier...only this was in Nov of '02.

No problem LPE SS, I'm sure LPE uses the best springs possible for each application and it might differ a little and it probably changes with new stuff coming out.

Which cam did you go with?

That was my thought too. I opted for the GT2-3 which is really a great stick. Idles beautifully, street manners are excellant BUT I think I (they) will be swapping it out for something more aggressive. I've been snooping around LPE (via phone) and I think they may have some grinds lying around that will fit the bill .

Please keep us up to speed on any new LPE grinds that are coming down the pipe if possible.

I believe this would add a bit to the total output across the board. The extra intake duration would allow for more tq at lower RPMs, and of course better breathing up top. I've heard the idle of the Comp 216/220 many times, and it is not exactly a "sleeper", but it follows pretty close.

In fact, correct me if I'm off here, but this might be the best "near-stock" featured cam for ls1s: much better tq and hp than the ls6 or similar cams, yet off-idle power and smoothness is very good, yet again it opens the engine up for better than average breathing up top. It would be interesting to compare this to the cam in question.

does the LPE cam sound like a sewin machine?

LPE SS

Sure does. Unavoidable really. As a result of the high lift the heavy springs make it sound like a sweat shop under there .

LPE SS . what set of heads would you recomend for the cam

LPE SS

Waving the LPE banner, I'd biasly recommend LPE's heads. This cam was designed around these heads so you could be sure that the combination is going to work.

For what its worth, they have a sale on their H/C package (heads, cam, 2.02/1.57 valves) for $2100. Pretty good price if you ask me .

LPE SS, maybe LPE could post the sale in the sponsor selection to help get the word out.

Dec flyer on LPE website page 3 has some details
