And I thnk they know what they are doing. They sell a complete package with Maggie making 800HP on a bored L99. Sticking with their CAM and Heads on a non bored L99 you should still have about 600HP at the back wheels.

Here is a good CAM: http://www.mastmotorsports.com/2010/...VT Cams&id=227

Or what the hell, trade you L99 in for one of these L99's http://www.mastmotorsports.com/2010/...Drop In&id=121

It's only money and your are getting some tax money back. Now you would have 6.8 Liters and kill Chris. Plus you would have 18 month warranty on the new motor and blower.

Or just see Ted and get what I got which would be called the 850 and you keep your block!!

PQ, what are you doing for fuel? With a cam you are going to need at least a BAP and a dual pump system will never hurt.

lol, ya, it's really hard to trust someone will really know their stuff. People are such A-Holes. Most of the shops around here are just guys who kinda know how to do stuff, or oil and lube guys. It's pretty pathetic.

Might be a good idea. Certainly easier.

But, I still will need to know what to do when I'm ready. So I want to nail this down. I may be getting some suspension stuff anyway. install on that stuff is pretty easy.

You dont need a huge cam with a supercharger , you can always add boost to get where you want. Alan futral in walker la. is well known for custom cams also maybe call him .

And 550ish is all I'm wanting I guess. But I DO want it. I'd like to shoot between 550 and 600. Then throw some DRs on and see what it'll do. Like I said, suspension will be done regardless.

You spend my money well Scott.

But my tax money is all going to advertizing allocation. So I am still limited.

PQ, when I was debating this I came up with this. The LS3 conversion is more $$ to do but I believe that you can rev the motor higher, thus getting more peak hp ( which is not really useable on the street), and since you need to change more parts you can get more durable parts. So ls3 conversion = more peak hp + better parts and durability

Staying with a VVT cam will cost less and provide you with the better low end tq but less of a peak number which you don't seem to worry about. Can you tell the difference between 540 rwhp and 570 rwhp? I don't think I could.

Maybe someone with a graph can explain the difference in what the curves will be.

Has anyone with a Maggied done a blower VVT cam.

When I went with Ted's LS3 conversion and blower cam I also changed from 1 3/4" headers to 2". The rwhp went from 545 to 625. Rwtq went from 553 to around 600, maybe like 598, its late. But with the addition of that we had to drop a pulley size to regain the 2 lb.s of boost.

I hope that I did my part in adding nothing uselful and confusing you more.

Lets see how long it takes for someone who actually knows this stuff to crap on my theory!

Two great points that I had thought about in the beggining.

Reliability, and more power. Now, the low end power is actually more attractive. I am not chasing 600 or anything. Just 1320 time. But, higher end power can make up for a shitty launch. So a wash as far as I'm concerned. The reliability, which is what I started with, is still a big factor.

I will certainly be going with a BAP, but do NOT want to go further. Cost sucks. And I don't want to drop my tank.

Mad600SS who will be at C5 fest has a Maggie w/ the same cam as Dangeruss. Same installer too, who will also be at C5Fest

Then call every vendor on the site and get their take....compile all the research/info and make a choice.

But do the damn suspension first!

I called Mast and some others a couple weeks ago. I also had a couple of the "experts" spec out a cam exactly for my application...

Agree - Wheels/Tires first...

If I do the install myself, It'll be easier to not do the conversion. Plus, if I find the right cam in VVT, then the number of cam options won't matter. I can only pick one. Could be I need to find the cam and THEN make the decision?

Acutally it won't be any easier, no matter what you have to pull the heads to get rid of the AFM lifters. They ARE JUNK.

The VVT you can run a small cam and keep it or lose it and run a big cam.

VVT can Fail with larger cams and heavier valve springs so why leave that option open.

If you want performance with simplicity do the conversion.

Actually, I can borrow wheels and tires for the rear at the track.

Suspension first, power second, then wheels. Just rears. 18s with DRs.

This is how I've felt about it. I was a little shocked when I realized so many had kept it. And then read the claims of benefit. I'll be after the reliability chiefly. I'm still leaning conversion.

Oh, and Ted, I'm sending my tuner to Doc in Jacksonville and he's gonna put my tune on it so I can send it to you to add a tranny tune to.

Don't listen to Robert... LOL We will have plenty of tires floating around for sure... especially for the Team L99 captain..

The way I approached this one last month was... If I'm pulling heads, then I'm definitely adding LS7 lifters and I should never have to mess w/ it again. But in your case you don't need a huge cam so could get away with not pulling heads and going w/ a blower friendly VVT cam like a lot of folks are doing.

To pull the heads or not to pull... that's the question..

Pull the heads! All the cool kids are doing it.

I was yanking his chain, I have already offered to let him make a pass with mine to see the difference...

It's a community reaching out thing, kind of like helping old ladies across the street... Team LS-3 stepping up...

PQ, just do the conversion....you know deep inside you really want an LS3

Yup. I do want to beef up where I can. Just not pistons or the crank. It'd be nice, but cost.

Sportsmanship.

That's what it's all about.

In fact, I will leave L99 on my hood.
