I've got a DGV Weber (off 2litre OHC Escort/Cortina) and a small Crow Cam - can't remember the grind, but it's mild enough to be used with standard induction and compression ratios. Plus I've got the extractors and a 2" exhaust, obviously.

This is all on my 1600cc Gemini engine - I used to have a G180 in my last car - if only I'd done those mods to the 1800!!!

Put it this way, my 1600 with the listed mods would slay my 1800 which only had extractors and an exhaust.

Piss easy, cheap modifications that give pretty good power for the price, providing you're building on a sound base (ie, the engine isn't puckeroo anyway).

cam n traxtors are good but if u can get youre hands on a air compressor and a die cutter set, (and some guts) get the head off and grind the ports to as big as u think. but dont go to far cause u might hit the water jackets! a good cam to get on a standard motor is an ivan tighe cam grind no# 308.
