New carb

[Rifter_Chevy]

Im going to put a new carb on my 1984 K2500 with a 350. Its currently got a Quadrajet on it and the float is messed up, keeps staying pinned at the top of the bowl dumping in fuel constantly and flooding it out. I cant keep it running for long maybe 20-30 seconds by pumping the gas b ut it sputters and bucks then dies, and when i shut it off it pisses fuel out the passanger side of the carb for 10-20 seconds.

I've decided just to go to a edelbrock because i work all week and dont have time to spend time working on it on it(work 12 hour shifts) and i need the truck to get home in the morning and am at work now, so will wait till parts stores open grab a edelbrock and install it.

My question is what am i going to need.

So far i know im going to need the carb, obviously. Im also going to need an adaptor plate as i've been told the edelbrock uses different mounting holes than the Q jet.

The only thing im not sure about the the choke, right now its using some kind of hot air choke from what i can tell, im going to go with an electric choke carb to replace it with. Some people tell me i will need a block off plate on the manifold for the old choke some people tell me a 84 will not need this plate. Which is it?

Thanks guys.
