    SVA is a thing of the past. Its IVA now.
    As far as I recall any engine pre 1974 is visual smoke only. Anything after will be subject to emissions, to what level depends on the year.

    1980 engine so no CAT required, just CO <= 4.5% and HC <= 1200ppm per the IVA manual flow chart on page 44, here: https://assets.publishing.service.go...r-vehicles.pdf

    thanks for that dave but the question i was asking is do you have to fit cats when using a 1980 302 engine. i am aware of the emissions regs. i dont think you need cats but wanted other peoples views

    But the emissions regs are what tell you if you need CATs or not?

    Wot Aaron said. If you can't get the emissions down far enough with tuning and buggering about with jets and what have you, then you will need CATs to assist you.

    You'd hope anything but a very knackered engine of that vintage would be able to hit under CO <= 4.5% and HC <= 1200ppm though, I'd have thought? It's been a while since I had a car with a carb but even my old Renault 5 could manage that (and that was pretty knackered! )
