If they were kidding @HJmaniac , they would have said “ a horse walks into a bar and the bartender says, why the long face?”lol
GM Holden HQ Monaro coupe, 1971-1977. These came out in 173ci and 202ci inline sixes, the local 253ci and 309ci V8s and the 350ci V8. The fender badge will tell which engine it is but my eyes are not good enough. Gearboxes were the Traumatic, TH350 or 4-speed manual. Cheers, Harv
Your eyes are adequate. The photo doesn't have enough resolution for the engine size but it looks like it's a six of some sort.
