g5 cam specs
I made 396 rwhp with a HOTCAM and stock heads. Was it really a fast car? Not really. It sure was a pain in the *** (in my opinion) to drive on the street without programming.
Now Ive got a car that with some really fancy heads only makes "406 rwhp". I think its going to be a screaming fast car.
With any of these cams, look at the results in a configuration thats applicable (not a dual exhaust long tube vette for instance if you are running a MAC header F-body), and look over the entire power curve. MMS's 229vWhatever cam for instance, gives up loads of torque <4000 for the big numbers up top. I suspect that the G5 cam will turn out to do the same.
To enjoy your car the most, where do you need the power? This is a VERY important question. Very few of the folks on this board need all the power 5000+ rpm.
I suspect the G5 cam is like a 228/231 or so on a 113 with some lobes similar to the XE. I'll also bet that really nice longtube headers make up for alot of the low end issues that the cam brings.
But how many people here really need a 228/231 "ish" cam that really does beat the valvetrain around?

Not exactly a concrete answer to go betting about $1500+ worth of cam and install on...
Can anyone tell me if the G5 shows a lot of misfire codes at idle without tuning?
b) whats the big deal? its Lou's decision. if you dont like the way he runs things, then buy something else. the G5 make good power....especially with stock heads, but all purchases are up to the customer.

When MTI had just finished testing and development of the T1/B1 cams, we kept the specs secret for at least a month. I had the first 346ci LS1 car to pull over 400 rwhp back then. People also said that 112 LSA cams would be downright nasty for a daily-driven car, and many "experts" told me not to go with 112 LSA. Got to remember, this was back in 99 <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> .
Well, when we finally got around to releasing the specs (they did tell the people who bought the cams, but not until they bought them), several shops started copying them. Some of the shops even went as far as selling them as "T1" and "B1" cams by name. FYI, "T1" = Tony1 and "B1" = Brooke1 and we were both MTI customers.
Funny huh?
Now, as for copying the G5, I doubt that will be an issue this late in the game. There are quite a few cams out there that produce excellent results, and its not really that much of a testing/development criteria when it comes to designing cams for a stock cube 346ci LS1 anymore. Back then, 221/221 was considered "big" haha.

Reminds me of the 1st aftermarket cam I bought for my '98... I won't mention the vendor, but when I ordered it all I initially got were the .050 duration numbers, the lift, and the lsa. It took a major effort on my part to get a copy of the full specs, and that ended up being in the form of a bunch of scribbling on a piece of paper emailed to me after it had been faxed to someone else...

<strong>Thats interesting Tony, I didn't know they did that...well I hope G5 will eventually release the specs, it has been making some good power for everyone...I want to do heads soon, but while I'm in there, I want to consider stepping up the cam from my little cam which I currently have..its considered the "baby nuts" cam by friends...its a Comp Grind...222/222 .563/.563 112lsa...hmmm looks familar to another sort of cam out there.. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> </strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">just FYI, a single duration cam will perform better (due to the extra flow on the exhaust side and good idle characteristics) with heads than a split (especially like the G5). Lou will prolly get on to me about that one. thruth be told, with our intake restriction at high hp levels, its the exhaust side that makes power...big exhaust duration makes up for low head flow, while moderate duration goes well with exceptionally flowing heads (exhaust wise). all in all, a split WILL make more power, but it better be the right one. thats a little hard to tell...and a single does idle better...especially with fast ramps. if you are doing heads and want to step up, buy the GTP 226 grind or the new XE-R 226 grind. both will be plenty good enough for tens or atleast to completely blow away ET Streets. especially with heads, TH400, and 3.73's.
easy huh.

Comps lobe number is 3723 for that lobe profile.
Get it on a 114 or a 112 l/s with 4 degrees of advance ground into it.
Most any shop can get it for you with that info.
(In repsonse to the G5 cam owners impressions from an earlier post in this thread)
Having a cam that had idle probs and SES lights would suck. Keeping the duration in a "medium" range to avoid all that hassle sounds like the way to go.... to me.

Has G5 owners w/ programming had idle and SES problems? Let me know where you read this .. I am thinking of the G5 cam .. (no head work) ..

That could be the only thing new that we haven't see a lot of in the past. or might be considered different or secret..?

Looks to me like they pumped up the exhaust duration a lot to make up for the restrictive exhaust manifolds. This resulted in a "big 14 degree" split in the duration times, so they GM cranked up the LSA to 117.5 to get this thing to idle/pass emissions etc. Or am I missing something? Cause this sure don't look like a typical set of numbers for an LS1/LS6 cam.
