What year/model was the 308/253 known as a 5.0/4.2?

VH was last 308 (think last 253) VK was first 304 (think they dropped the 253 at VK) VN first 304 efi suss www.justcommodores.com.au (http://www.justcommodores.com.au) or www.justcommodores.com (http://www.justcommodores.com) (not sure which) for more detailed info.

ser 2 vk was the start of 304 VH and WB was the last 253's Bitch away guys !

But when did Holden stop using imperial and start using metric. My VH had 3.3 stamped on the side of the engine. Thats what I wanted to know.

arrr right . . . . why u need to know that ?

VL were the first with 304 efi as well. remember the ss group A's with dual throttle bodies?

as far as i know all commodores were refered to in metric ie 3.3 4.2 5.0, but the blocks were still stamped in cubic inches until the VK? , not sure exactly

i'd say the introduction of the 304

half way through VK they changed..

that's right. VK Group A saw the introduction of the 304 as engine size had to be reduced for Group A racing rules as the 308 was over 5 litres and would have copped weight penalties for racing, so they destroked it to 304 cubes and just under 5 litres (4.987). Basically, Series II VK onwards was 304. Series II's had the slide doorlocks vs the pullup door locks of the earlier models (except those cars with central locking of course). As someone said, first EFI 304 was VL Group A but prototype was actually in a VK SS.

Jeff, u da man!!!!

i knew i was right Some original photos have not been recovered yet.

in the 6cyl ive seen blue 3.3 and 2.8 think it was in VH's

I've also seen a 4.2 in a VH.
