Hey Guys need some help.. broke the carb body on my 3 port alpha (non ABI / standard version), they cost $130

and I was wondering if Nova or OS carbs can be used... I read that some people use .18 carbs on .21 engines to improve fuel time, sacrificing a bit of power....
Never the less I have a nova P5 and a 327, and an OS .18.... Just wondering If any of you know if these can be used????
P.S. The motor Idles great like usual, but when punching the throttle it bogs and will rev inconsistently, and of course flame out.
