Trust me guys I am not cutting into this intake to put a giant carb on it, last thing I need is for it to fall on it's face every time I punch it to get out in an intersection I've been there, a 500 was good enough for the factory it's good enough for me. Honestly nothing is wrong with the two barrel really I drive this car to work more often than not because it gets way better gas mileage than my Sierra and of course better gas milage mileage than my gtx. So I get there is a lot of knowledge about 273's on here but one more question. I am exploring the idea of long tube headers because I do have original manifolds, but they and the pipe attached to them are really the most ate up parts of the car, it looks like a 51 year old car underneath with 90 year old exhaust. Now I would like to know without building custom headers if anyone knows of a pair I can buy that will fit a barracuda with a 273. I ask because it's an awful tight turn to hug the block to get inside the steering column and then kick out so I don't have to pull the engine to change a starter. I would really like to avoid custom headers but the last thing I want is to get a nice set of headers in the mail and start bending the hell out of them so my starter still has a place to live. I'm open to short tube headers as well if they fit well I was just exploring long tube because if I have to redo the pipe it would be nice to size it all up from underneath the car already.
