And it sucks that your parents seem to look down on the car building hobby, most people do nowadays. But it's your parents house, your parents pay the bills, they make the rules, even if they aren't to your liking. If you really can't get a crate motor, you can just rebuild the 305. Don't go crazy, but you can just do normal hotrod stuff to it and it will run perfectly fine until you get your own place and garage space. Tear it down, mark where everything goes, put everything in Tupperware containers (not your mom's) marked with what goes where, take lots of pictures! For example when/if you take the motor out, turn it to TDC of the compression stroke on #1 and note where the dizzy is, where the vacuum advance canister is pointing to, where the rotor is. Then bore it .030 over, higher compression (aim for 9.5:1 for pump gas), bumpy cam, dual exhaust, recurve the dizzy, and away you go.
