VVT Cam .......... or ......... LS3 Conversion - Page 3 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Yes suspension is also another priority. You will notice a lot more of use with s/c's working on suspension at the same time as thinking about cam. I have trailing arms, toe rods, and rear cradle inserts(very goodmod). About to look at axles after cam and stall are in before sticky tires. None of us can do it all at once but I can say from experiance that there are mods out there that you will get more benefit from other than power ( yes it doesnt sound as nice) but its true. Most auto guys would say stall first as well because for the money it is the best mod for auto and it will get you down the track quicker all day long if you compare stall and no cam vs cam and factory stall. The gains of power are good but its not beneficial unless you can hook it!!

haha I said something smart and on my 1k post!!!!

Ok. So we may get somewhere with this.

A stall and cam at the same time.

Suspension mods for hooking. (trailing arms, bushing, etc.....)

So then, I still need to figure out what I think would be best. VVT cam, or LS3 conv.?

In order to not have to revisit. I wanna figure out my process.

Maybe a pros and cons of VVT and LS3 according to C5 member opinion.....

If I was you...this is what I would do :

1. Rear subframe cradle inserts
2. Trailing arms ( do the rear bushing as well, only the Pfadt trailing arms come with both the front & the rear )
3. Drag radials ( worst case, put them on your stock 20" wheels )
4. Decide how much power you want to add
5. Big power => LS3 conversion ( match stall to cam choice )
6. Smaller gains => VVT cam swap ( match stall to cam choice )

You probably wont get a lot of "valuable" information on one vs the other right now from members other than the ones with LS3 conversion say:
I have better/wider cam selection
I have good lifters now which shops say is a weak point
I spend more money lol
I think I have an ls3 now?

Those with VVT:
I have the best of both worlds
Its cheaper and easier to install
I kept my weak lifters or I chose a VVT cam with afm delete and got rid of them for a little more money.
I gained more low end torque then you LS3 guys and maintained Same hp as your cam.

If you want a big comparision what you see from the vendors is the best for now as really VVT cams for the camaro are just now starting to get into peoples mind and engines. If you want more one vs the other from actual drivers then wait.

That will give you some time to do the other things!!! Not only do you have to decide ls3 vs VVT but also VVT vs VVT with afm delete

I don;t understand why people are saying LS3 conversion is the only way for big power.
Many L99's are making big power on VVT cams. Granted, some of these results are with heads too.

Something to consider is that the LS3 conversion leaves you open to MOAR POWER later. But then, you're not likely to want that.

Because my LS3 with a sub .600 lift is at 470 RWHP without touching the heads.

Not knocking those 2 threads, trust me....475 RWHP out of a VVT L99 is stout, but you can make some insane power numbers with a big cam in a LS3 that you simply can't stuff in an L99 because of the lifters, and possibly piston to valve clearance.

He could always switch out his maggie for a TT and keep VVT with a cam.

That would be pretty expensive....he's already got the blower and headers.

TT would have had to have been decided from the word go!

There is something to be said for lift as well as the lifters that the l99 uses. Opening the valves more to allow more air and fuel mix isnt a bad thing..LOL
Also an automatic trans eats more power than the manual..
