ID on a 308?

[vkwalks39]

Hey guys, I've have a quick question. I just been givin a 308 it runs, but, i'm not sure on it, if is a blue or a black motor or even a red... The first letters are QR*****,Thanks heaps

[88GreenVN]

The QR puts it in the HJ - HZ range. But you probably know that already

Found some QR's in the HG's too. So it's probably a "red" motor.

[vkwalks39]

Thanks for that mate, the motor came out of hq prem. I just wasn't sure on it. Can you put a red motor into vh, Which has a blue motor?

The A is very Faint, but the VJ are clear......Maybe just VJ, Not sure..

I've not found a VJ as yet - VT yes but no VJ or AVJ

[GOTMYN]

Really???
Wow, It's apparently a Black VL Engine, so I was told when I bought it...

Maybe stolen recovered or something???

If it is a 'QR' engine number it is a red 253 out of a HQ (and maybe later models). 308s were 'QT'.

Statesmans had '11' in front of the 'QR' or 'QT' number.

Torana V8s were 'HR' (for 253), 'HT' (for 308), and 'HZ' (for 308 L34).

Earlier Aussie V8s in the HK, HT, HG were '253H' and '308H'.

It's been a while since I played with the V8s and the info is 'as I recall' so don't flame me if I'm mistaken anywhere.

[GOTMYN]

I found it on Google...



VT - VB to VK 308 (red, blue and black)

VA - VK 304 LV2 standard

VB - VK 304 early 1985 manual only V5H (a good ún )

VC - VK Group A (engine painted red) inc A9L

VG - VK 304 late 1985 manual only V7X (same as V5H 'cept no Brock heads)

VJ - VL 304 (not GrpA)

VZ - VK 308 V5H

VW - VL A9L (GrpA)

It's a 308 because,it has stamp on the side of the block. It's sitting in my vk.Oneday, i like work it but stay with the old skool look..

[GOTMYN]

Going by the codes mine is a 304...But it has 308 on the block, what was the difference? Crank???

[vkwalks39]

I don't know mate, maybe the crank, or maybe holden just paying funny buggers... What should i do with my vh commo. I travelled 560kms a week from home to work and using $140.00 in fuel for the fortnight or just. It has a blue 202 with 4spd. I'm doing the speed limit to. We are playing 1.65.9 cents ot a litre.

I read somewhere that it was a small cylinder sleave to take it back from 5.0L 308 to a 4.9L 304.

^^^ this must be untrue then... If the crank was reground.

close HR (308)+(L34), HT (253),,,HZ not sold to the public only 380 unit's made.

was that only 380 HZ 308 L34's made with a HR prefix?

[burnz]

no HR prefix 308 L34 option, there were the slr 5000 sold to the public

HZ prefix 308 L34 factory race team's had first dib's production run less than 380 unit's

Mate, you might want to check some of your facts before you put them on here.

I stand by the info I gave in my first post.

[burnz]

yep pulled the book out (yes i can find my thing's)

HR=253
HB=253 export
HT=308.....240 bhp
HT####L=308.....250 bhp
HZ=308 L34.....349 bhp
HZ####R=308 L34...### bhp

From memory, the crank was re-ground to shorten the stroke by about 0.050 inch (a bit over a millimetre) to bring the capacity down from around 5047cc (308 cu. in.) to 4960cc (304 cu. in.). This brought the engine under the 5 litre international competition limit.

The old 308 block with it's 4 inch bore was retained. Not sure what was done with the rods and pistons.
