So I am thinking about changing the carb on my 292. It currently has a 2 bbl w/ electric choke. I dont know who makes it. I thought it was a Holley 2300 but the rebuild kit for that carb had almost no matching gaskets/seals or parts. The guy I bought it off told me it came off a mid 60's Y-Block. Im thinking about going to a 4 bbl and wondering if the Holley 4160 will bolt straight up to it, or do I need a new intake manifold. This is a daily driver and I'm not looking for huge horsepower numbers or anything, just want it to be able to scoot alright. If I need a new intake manifold, I think i will stick with a 2 bbl. So that being said which way should i go their. I would like to stick with an electric choke regardless.
