The Chev is 100% beter than the old holden V8's, iv rebuilt & owned both !
253, 308 Holden.
327, 350 Chev.
The Holden V8 was originaly a Buick engine but was shelved due to its poor valve train system (your've heard the Holden ticking away next to you at the lights ).
Holden bought the engines & didn't fix anything, just threw them in.
Plus there are sh!t loads of aftermarket perpormance bits avalable for the Chev too.
The main reason people use the Holden engine in conversions are that they are cheap & easy to find.
Sorry I've seen some Bullshit in my days, but thats a very biased and ill informed approach you have there old son. Not slammin' you but hey...
If you think that, you can stay back in the dark ages all you like.
Round you up and go past you everytime, as i have all to many times before from people with comments like that.
Now the black and white facts.
A factory vn onwards commordore v8 engine will give you good service and a favorably lend to a engine conversion with minimal expense and modifications required to the engine to prevent oil surge and control. The late v8 holden efi engine has good after market performance products avaliable if required and lends itself to modification...if so required. Combined with the factory auto trans, your onto a winnah !
Any chev conversion is firstly inhibited by the first common fact of.
The engine is not produced locally. Importations and serviceable components are not a readily avaliable as that of its aussie counter part.
Chev engines (all be that old school engines) are deemed performance application engines and thusly regular spare parts suppliers do no commonly stock out of date chev components, and the ones that do expect to charge you like a wounded bull. An import used chev donk also runs the risk of high mileage and freeze cracks in the blocks.
The number of importers of chev engines I believe has also dropped due to lack of demand and increased importation costs.
(Example...ring the boys at superformance in brisbane and just see how many engine they imported in the last year..the also have nil Big block stock as well)
I've owned and built many of these engines in the past as well. Side by side, they both have awesome potential. The only thing i faulter the aussie engine on is it head stud configuration which can lead to blown head gaskets more readily in over heated situations. 4bolts v's 5 bolts.
Heads studs and o'ringed blocks on both engines leads to trouble free motoring.
Power output is much the same in given capacity engines.
aussie senator 355 v's chev 350...aussie donk wins every day.
Well thats been in my dealings.
F.o.r.d engines can be a viable option as well for bang / buck option as well.
It just a shame no one does a big block chrysler adaption for conversions here as they are readiliy avaliable now and can be had for as little as $600 for a running engine..
it went harder than my uncles 5L (4.9) VK Brock (HDT improved mate, check out da momo's)
