Took Her Out For a Run Today and There Has To Be Something Wrong...

[Chance72]

Well guys just drove my 72 up the highway to put gas in it and when I was driving my speedo was saying im going 90 and everyone around me is goin faster than me and the speed limit is 65. Also it seems like it has no power to it whatsoever. I mean yea its a 305 but it still should have some power. I couldnt even get to the speed the people around me were going, if I tried it would start shaking real bad and Im to scared to try it. It also smells like somethins burnt when I get out, not bad but I smell it. I got home and lifted the hood and woah it was hot under there... Like really hot. I really need to get this checked out if Im going to use this as a dd. Is it cause I was pushin the 305 to hard or what? Im thinking if this is how its gonna be, Im going to have to get some cash to do a engine and trans swap... I only have 3 gears and its pushin itself hard to get to like 50 mph.. BUT good thing is I got to drive her some and saw a 69-70 chevy pull up to the station, was patina dark green. Old guy was driving it, didnt seem to interested in anyone around him, filled up and left.
