Heya all, just wondering... Are there any visual differences between a chev 308 and a chev 328?? I'm looking at buying one and only going off one picture, and the seller doesn't know what engine is in it.
Please let me know if there's any differences visually better the two.
Cheers

It's a 308 out of a old Holden. Slightly bigger bore than a 307 but basically the same.

253/308 were GMH and GM South Africa only; that engine family was never offered in the USA, etc. It was its own engine family.

I'm from New Zealand, hoping someone would know the difference? Are there any visual differences between a 307 and 327?
Cheers

If you really do mean a 307, and not a 308, the engines are externally almost identical, assuming they are the same year. The most reliable way to tell would be the production code stamped on the block deck just in front of the RH head.

As for a 308, I have never had my hands on one, so I can't offer any help.

GMH V8 went into a lot more markets than Australia and South Africa. GMH vehicles were sold into most RHD markets, and the HT-HG Holden and LH Torana (with 253 and 308) were both built LHD and exported into LHD markets. You will find Holden V8 engines sold into:

RHD Asian markets (Japan, Malaysia, Thailand, Indonesia etc). vehicles were actually assembled in Asia.
New Zealand (also assembled here).
Fiji.
Japan.
Tonga.
New Guinea.
Pakistan.
Most RHD West Indian Countries (vehicles assembled in Trinidad).

Of the LHD markets for Holdens that I know of were as below, although finding a 1960's Holden in Hawaii today would be near impossible. Mid-late 90's export Commodore and Statesman (normally badged as Chevrolet) would probably have the 304ci EFI version of the Holden engine (replaced by the LS1 in 1998 in passenger vehicles).

Angola
Bahrain
Chile
Greece
Guam
Hawaii
Iraq
Iran
Kuwait
Lebanon
Mozambique
New Caledonia
New Hebrides (Vanuatu)
Qatar
Saudi Arabia
Samoa
Syria
Tahiti

Plus many more. Local assembled vehicles often had local engines for smaller engines, but the V8's generally came from Australia.

I can't find a picture of a HK-HG Holden in Hawaii anywhere on the 'web, but here is an article about a Hawaii delivered LHD HR Holden (the pre-decessor to the HK):
https://www.tradeuniquecars.com.au/feature-cars/11...


The Holden V8 engine family ran from early 1969 until 2000, and had the capacities of: 253ci (later 4.2L), 308ci (later 5.0L), 304ci (badged as both 4.9L and 5.0L) and 350ci (5.7L).

I've never seen (or heard of) a 308 or 328, so I would have no clue. Are Holden V8s Small-block Chevys?
You will probably need to tell us the differences.

I think the OP was looking for a 307 vs 327. I was just adding some background to the thread on what a 308 is.

In some instances there is bugger all difference between a 307 and a 327, example a 327/210 vs a 307 would be only pistons (as in bore size), dizzy graph and slightly different tune in the 2-Jet carby. And of course the casting number on the back of the block and the engine plant suffix on the engine number pad.

Here is info on the GMH V8 if interested:

Goodaye all
Big visual difference is the water pump, V is also a little narrower.
Water pump bolts to the timing cover on a 308 and goes over on a 327.

Had 2 gearbox bolt pattens for the gearbox.
Chev patten and Holden Trimatic and Aussie 4 speed.

You can fit a chev crank and rods into a 308 and get 383 with a little work.

Its up too you which you pick, here in Aus its easy enough to get parts for both.

l have Grp3 that used to eat early LS Chevs.
Still no slouch.
