yeah from what iv been told the 350 hololey is too small even for a 253, good for a 202 though, my mate had one on a vc 202 and it flew, yeah beast beat is to get the carby rejetted, unless ur chassing big power and doing engine mods to suit, i'm hotting up my vk 308 and am still toying with the idea off rejetting my quaddy or bolting a 650 holley on, at the moment the holley is winning for me, but mines not a daily driver and i'm putting it on a mildly worked 308, good luck though.
