How much for an L67 cam install?

[Fletch_QLD]

So high ration roller rockers are a poor mans alternative to a good cam - given that it's a bolt on mod at DIY level - but searching the forum tells me that $600 and an hour or two of DIY will get me 5-10 extra kw.

I have an L67 running 10psi - the question is, how much to get a cam supplied and installed - and what sort of gains are we talking (for something that remains subtle enough for every day use)

High flow cats and a decent cat back are on the way - but looking at the engine first.

cheers

Hmm for a cam is about $600, then you will need new lifters $250, depending on the profile you may need new springs, collets, retainers (though that applies to rockers too). Possibly new cam bearings, not sure on price. Then you get too labour. I would work on about $1000.

[Fletch_QLD]

All up $1000 I'd jump in for sure.

Any recommendations around Brisbane S'Side

[airforceone]

id like to hear were in bris too,

[acarmody]

No I would start at $1000. Find a decent engine builder, they will do it, and ask them what they would charge. Also check out MACE since they sell L67 specific cams, Mace Engineering Group - Specialising in powering Australia's best Commodores | Automotive performance accessories

You can change the cam with the engine in the car but I'm not sure if you can press new bearing in with the engine still in.

Chilton's Engineering, The Gabba.

I've seen that name a few times, maybe give them a call?

Stage 1 comp cam from mace engineering : $650

They say :
"This cam was designed for use with totally stock heads. Stock springs, collets, retainers, lifters and pushrods are fine. Springs, retainers, and pushrods are recommended for shift points over 6200rpm. <...> Look for gains of 26-37kW depending on your car's current configuration.

So I take this to mean that the cams drop in without replacing anything else - but keep it under 6200rpm ?

[acarmody]

Yeah pretty much, but that's OK since your not making any power at those RPMs anyway.

If the springs, retainers, collets, etc, are worn you will still need to replace them. How many KMs has your engine done?

[Fletch_QLD]

I have 150000ks on mine. I guess I'd be guided by the 'installer' on what needs replacing.

[acarmody]

Hmmm may need replacing or may not.....yet. But some parts will last ages while the same parts in other vehicles can die sooner, luck of the draw really.

Just make sure you tell the installer that you will source all your own parts, that way they are less likely to suggest replacing things that aren't needed.

[Fletch_QLD]

Sweet - I'll give chilton's a call and we'll see what they have to say.

thanks acarmody

Your welcome, good luck.

Hey mate just been reading this and wondering how you ended up going with it?

[Fletch_QLD]

I was advised my top end would need a freshen up with a performance cam. The numbers they were talking burst my budget bubble so I decided to leave it.
Basically it was suggested I'd have no change from $1600 if everything went well. Planning to open up the exhaust and revisit the cam at a later date.

[Greesie]

Cheers mate, shame it blew ya budget out always such a disappointment when ya get an idea in ya head...happens to me abit haha good luck ne let us no how it goes if ya get there

I got quoted 1200 for cam, double row timing chain and tune. Then it was atleast $600+ for installation. Cam is a very dear option and i have also have put it on back burner

wow 1600 odd dollars for a 26-37kw gain or have i read it wrong

Pretty much. Plus if IMO id be looking at cam bearings, lifters, everything. So it would cost more. I don't see the point of sticking a cam in a tired engine without doing the rest? It would be ok in a fresh motor to just plonk cam in on old bearings.

[Fletch_QLD]

The thing is, it's not just 30kw, it's 30kw more. Initial mods are relatively cheap for each kw gained, but the further you go, the higher the cost per kw gained. Every time I reach a point of saying no more $$ I eventually get the itch to get "just a little more power", and each time that "little more" is going to cost a lot more.

Then I tell myself, I'm never going to get the Calais to go as well as as a falcon with a factory turbo anyway.

Then, if I got myself that FG turbo G6E, I'd be looking at how I could get "just that little bit more" ...

[Greesie]

Haha yep that's pretty much how it goes, regardless of your stage your always wanting just that little bit more, never can be content with were it's at haha
