Looks a bit of an untidy conversion.
With carbs alone on a std engine you wont see much power unless you really sort the hot air problem. And you can already see the lack of space on that install.
power wont be upped dramatically, and you will suffer in terms of running smoothness, pain in the arse starting and cold running. Itll hate the weather opposite to what it was setup in etc etc.
Pretty useless really. If you want individual runner performance than throttle bodies is the only way really. And you can get space saving bodies allowing you to run a nice airbox and remote pickup.
