Isuzu G-series Twin Cam

Just been thinking abit - all the DOHC extractors ive seen fitted to engines in AUS are similar in design to SOHC engines. I wonder how much better this would be for top end flow...

i saw them a while ago. there bloody nice. i think if you had a set of extractors like that on a single cam it will have better top end then most the ordinary one's i see getting around. probably $600 to get a set made or more.

for some reason the extractors ive got collect cyl 1&2 3&4 what the fook were these people thinking when they were made??????

probably save half an hours labour and a couple bucks in material. ive brought extractors done like yours for $50 second hand the extractors i have now are worth about $500 but work well.

Oooh, that looks so nice...

So you don't see many of them going around?
