Just had the VL dynoed today and was suprised after a quick tune up and a few adjustments in timing i got 135 rwkw (180hp):)

The engines stock bar manifold and carby. I dont know what you think but i think thats prety good.

just carby/intake mods, the rest is an unopened VL 304?


thats fantastic if so, considering they only made about 122kw at the engine when new

Nice, be torquey to hey? Must have a decent exhaust/extractor combo on it?

Okey
18-08-05, 20:34
yep the only mods iv done is 650 DP holley. performer manifold and the extractors that the cops had on it. The next thing to do is get pacemakers and a decent exhaust thinking 3" single.

Yeah ive got twin 2.5" outta the pacies, to single three inch...

all depend on future mods on what size to go..

Ive got a single 2.5" from a set of pacies... no need for me to upgrade that until i do some engine work methinks.

Okey
20-08-05, 19:01
yeh the reason for the 3" is the posible up grade to a strocker engine 355 or 383.

im pretty sure that vl's never had a 304, why do people think this? they are a 308.

That is good. My 308 with Pacemakers, 286 Hydraulic and flat tops (On LPG with a carp carb) made about 132rwkw.

here we go again about 304/308

People dont think it , cause all VL's had the 304

do a search mate

sif newb!!!!11

in about 1985 when international group A rules changed it required the V8s to be under 5.0 litres, so they went from 5044 or what ever to about 4950 or something... thus 308 to 304 midway through the VK's life, and any holden V8 after that was a 304

good stuff! how many K's has it done?

all you need now are some ported VN heads or L34 spec 308 heads and a cam and you'll be set for some more decent horsepower!

they are a 304 because of the group A race Cars. had to been under 5 litres so they destroked them to 4987cc so thats why they are 304s also they run unleaded as standard not like the 308.

Now I know im pretty new to all this stuff...

But, arent L34 Spec 308 head's PRE-Polluction.

And 304's come with the pollution gear, Will this work, and just be illegal, or will it not work at all.

ADR27A didnt really affect port & valve configuration, was mainly about having EGR equipment and charcoal canisters

Go the VL 304,some people think because they were 122kw stock they were crap but it doesn,t take much to wake one up with some breathing mods and a brock cam.

Yeah bin those heads! Thats what killed em.

Theres nothing wrong with VL heads,I used to think they were small valve but they are big valve unleaded heads,nothing wrong with that,whack on some extracters and fill her with some premium and off ya go.

Even Wheels magazine described them as breathless ie. Wheezy!!!
Dont hear of many people retaining the stock VL heads on their hotties!:D
You may like to advance the timing with your tank of Premium aswell...just a thought.

My VL motor still retains the std heads and valve sizes , ports have been opened up a little and it makes a tad of 200 rwkw .

Im looking for a decent set of heads for my car atm, But really have no idea what im looking for, whats something thats not going to cost me and arm and a leg, but is going to flow abit better then the Stock 304 Heads ?

What will a set of VN heads go like ? (stock ones, havent been ported)

what else have ya done to reach that.

Okey
23-08-05, 19:32
I was lookinh at new heads but it was going to cost to much to change over to VNs. Ill be puting on VNs when i do the engine rebuild so it all can be done at once, new heads, cam, stroker internals etc.

Stable
23-08-05, 20:43
VN efi heads go for around 800$ i think. And flow 500hp in stock form. Good heads.

NSNPWR
25-08-05, 12:35
Definately proven performers but then you gotta do inlet manifold (or EFI conversion probably just as cheap) and new extractors............$$$$$$.

wagonshaw
25-08-05, 14:22
b cast heads are also proven to be excellent performers with the right cam choice to match the head work you can get a more than respectable streeter. check out tha K.E.C website as they have some good info on these heads with their cut n copy.

think its www.kec.com.au

NSNPWR
25-08-05, 15:17
I used to work with a guy that ran the Bcast heads on his 355 stroker, cant remember what cam/manifold/carby combo but it did run 11.7@113ish on G grids filter and pipes off with Hornet scoop. Was a very basic setup but made good grunt and hooked up hard.

Okey
25-08-05, 19:45
I need to know which way to go soon as i need a new exhaust and extracters so you can apriate the spot im in. stick with the heads and get the new exhaust stuff done and use the heads or pray and hope it holds up befor i can afford to do the heads etc and then replace the extractors????? do yella terra or the alike make performance heads that will go on that block but still pre EFI heads??

Boyracer
26-08-05, 00:07
I think yella terra might still sell pre VN alloy heads but I still think VL heads have potential.The VL group three Brocky used pretty much the same heads,what cam are you using?The wade 242 is an old HDT favorite.

Epitaph
26-08-05, 08:41
dont do an efi conversion. run VN heads with a single plain manifold, big pacemakers and a 288 solid cam.. :D actually, ELA-RE built something along those lines..

wagonshaw
26-08-05, 12:29
what sort of quarter mile times are you after anything upto high 10s stay with your B- cast heads but high 10s or less then go VN cast heads. stay away from the yella terra heads no use and too expensive

Epitaph
26-08-05, 14:03
value for money i love VN heads.

people skimp on heads.. dont be a tightass. im gonna buy some alloys soon

but arnt the vn heads injected ?? by changing vl 304 heads to vn heads mean that u need to change to EFI??

NinetySix
26-08-05, 16:12
the injectors dont go in the heads tho

Epitaph
26-08-05, 16:15
but you do need to change the extractors, cam and manifold

ITSGMH

nope, but you do need to change the cam, headers and intake manifold, as the valve config is different to the older VL and earlier heads!

Okey
27-08-05, 12:56
The VNs sound the way to go. just have to work harder and get the engine rebuilt sooner with new cam etc and hope the current exhause holds out and i dont get pinged by the cops lol. cheers guys.

09-10-05, 18:40
guys it is quite simple and very black and white, vl's although running 5.0 badgework, are really a 4.9 or 304ci, if people wanna argue over this start a new thread
