1966 chevy malibu 350

hello, this is my first post so good to meet yall.
im looking into my friends 66 malibu with a small block 350.
ive looked the car over and i am pretty into it for th 1700 $ tag
i was wondering if anyone could give me a list of points to look over before i buy it, where to look for rust and what not.
also i would like to convert it to a manual transmission if possible seeing as thats what ive raced primarily, could anyone tell me if this is possible.
any other performance tips and upgrades i can apply, i have about 6 grand to put into the car.

thanks!

buy it! 1700.00 sounds like a steal.is the motor stock.i assume so for that price.add cam,headers,intake,carb,and hei ignition [if it has points].dont go too big on the cam though or youll start loosing horsepower.personally i like my camshaft to have a good lope.i would definatly go with a 4 speed.it adds value to the car and they are soo much fun to drive.i ould then complete the needed bodywork[i would make an ss clone].also if it doesnt have front disc upgrade that too.
