Originally my plans were to build and run either a twin turbo, or single turbo LC2 engine out of a Grand National, and stuff it into another 3rd gen project powered by Dynamic EFI's new SFI-6 Engine Management Control and run it as a 10.0 daily driven street car. Buick builds have been done to death though, not so much on this board, but on other boards that I am apart of, so I figured why not use the existing V6 engine that came with the Camaro just like I am doing with the GTA build. I will still be able to use the SFI-6 anyway, its just that the parts selection for the Chevy V6 isn't as broad as the Buicks are. This is the Camaro that I have my eyes on, but there is another one that I am considering as well, same as this one, but convertible. I will update this thread as soon as I get either one of those cars in my driveway. Will definitely be a fun project...

 

dont go with the convertable car it will prove to be to heavy for 10's in the long run

 

F

 

Shouldn't be too much of a big deal, the added weight from the factory convertible bracing would be removed when the sub-frame connectors go on. Can easily get the car down close to 3000 pounds when all is said and done if I go with the convertible because I plan on major removal, although I am leaning more towards the hardtop to tell you the truth...

... hey are you grading me lol?

 

i dont belibe the factory bracing can be removed, but not 100% sure on that
even still i think the vert would twist up way to much , even my hardtop car has inch long cracks int he roof panels behind the doors

honestly this is what its going to take to get into the 10's

driveline wise

3.1 setup to turn 7500-8k rpms
66mm turbo
a good trans with brake knowing u that would be a 2004r which is a good choice
stock intake has to go , u have seen my pizza box so i know u could build urself one
atleast a 3:73 gear

id aim for around 2,800 pounds which is more then doable with the v6

 

Normally when we convert from either a hardtop or t-top, rather than install the factory side rocker bracing, along with the spider caging behind the backseat, we just install a set of sub-frame connectors instead. That is essentially most of the weight in a convertible right there. If I go with the convertible, that will all get removed... as I'd have to cage it anyway, so it won't lose any strength by cutting it all off, it will only gain strength from the cage and SFC's. Now if I didn't plan on SFC's, then the factory bracing would need to stay.

Power wise, I'd have to take a look at my options. Definitely want twin turbo's, as I already have the rendition down the way I want them. I'm not even going to bother with iron heads anymore, as the GTA was the last of the porting that I will ever do in a very long time to come. I will more than likely go hybrid with the 3.1 to rival what is out there for the LC2 crowd. I'll pick up the pace on this project once the GTA is out of the garage and on the streets sometime tomorrow...

 

... and you know me, I'll freaking do it, too lol.

216/228 & 454"/480" @ 112

bad cam its ground on 112 very lil lift

call dleta they will grind u something custom shoot for .525 lift

 

Oh my goodness, you know very little about camshaft selection. You can't say "bad cam" without knowing the rest of the engine build, nor my target RPM. What we have in mind doesn't call for that much lift, and how exactly is a 112 LSA bad for a turbo charged application? There is a reason why LC2's run between 108 and a 112 LSA, and there is also a reason why they undercam their engines, not to mention a reason why their stock LC2 cam has been mid tens with way less duration and even way less lift than the Crane cam I might go with. Why would you recommend a Delta camshaft? I honestly wouldn't install a cheap Delta camshaft into any engine that I build, I'll leave Delta's for the Honda crowd. But I digress...

Anyways, back to the build...

 

cause ive bene playing with these engines for along time and know were both the iron heads flow and were the aluminum heads flow .


that cam has to much ex duration compared to the intake and not enough lift

these engines want a seperation of 6* from intake to ex side and .525 lift for iron heads and closser to .600 when using aluminum heads with a roller cam


if u really want to do a badass engine skip the standard variants or hybrids and build a 3.4 dohc engine , u could drop on of those in slap a 66-70mm turbo on it and make 500hp by accident

those heads flow well above what a set of ported aluminum heads do out of the box

 

Is this a build thread to a car you dont own? Lol.

Custom cams arent that much.

Project 89, whats wrong with a 112lsa? Jones cam designs ground mine and orr's on a 112

 

nothing when the cam is right , but he picked out the n/a 272 hyd grind which has a ton over overlap needs high comrpession high gearing

not to mention the lobs on that cam are friggen lazy ,

the only 272 cam worthwhile is the mechanical , the hyd and mechanical versions of the 272 are very different

i have my cams ground on 112-114 depnding on how much duration they have

anything over 272 adv i goto 114 and i have some cams that are 280+

 

I like this thread. Ill be following it!

My 2 cents on the delta cams... I like them. Mines just a small one but never had any issues after 5k hard tuning miles.

Also to be honest Ive been looking for another V6 Camaro hardtop to mod up. Toss my crap onto so I can paint my maui one and make it a street car again that is not for donuts and burnouts..lol. Ive had this car for 10 plus years and now that I can afford a beater to mod up I figure why not..lol

 

Guys come on, I already know what is in store for this project, I already know the direction I am taking this way ahead of time just like my GTA project. This thread is a chronicle for something that was being planned for awhile now, a chronicle that I am sharing with this board. I am not looking for advice, I am merely sharing the build. Only difference now is instead of it being a twin turbo LC2 I am doing it with the original 3.1...

Umm, I own it now, but please keep stupid remarks out of this thread, k...

Custom cams don't mean anything at all, don't need one...

Nothing is wrong with a 112 LSA...

 

Thanks Mark, but I asked Joe to close, lock and delete this thread. It was a mistake to even start it here. I'm going with the twin turbo Buick V6 in this Camaro build afterall...
