Hi guys. I've read from a few sources that back in the day guys were throwing 4 barrel carbs on their 318's that came with 2 bbl's on them from the factory to get a little performance boost. my 73 road runner is completly stock. i was going to just drop a bigger engine in, but didnt want to go through the trouble of changing the transmission and rear end out to handle the power.

would it be worth it to slap a 4 barrel on my car and would i notice enough power to make it any more fun? if so, is there a specific one that i would need that works with the 318 from 1973? also, what other mods could i do to that engine (without major tear down) to get more out of it? i'm not lookin to make it a fire breather. i know its just the 318. just want to make it a little more fun.

i've got a base model 73 road runner with the automatic.

thanks in advance!
