    i've had many tree fiddy's.

    i was thinking motorwise doing a 383 stroker, but i'm wondering about the other stuff. this car will act as a cruiser/daily driver/weekend warrior/soundoff car.

    the 305 is not really a good motor to mod, but it does last forever. I've seen 305s with over 200k on the clock running as good as new. The problem comes with the 305s differance in bore. Insted of being 4" like a 350, it has a relitively small 3.736" bore, and the same 3.48" stroke. The combination of a small bore, and long stroke make this engine very prone to detonation. However all the SBC heads and intakes will work, as well as cams. Make sure if you decide to do a build on a 305, you do your calculations carefully, and be conservative on compression and timing. You can get a 305 to crank out a reliable 300hp, but don't expect much more without diving deep. For the money though, the 350 is a much better option.

    sounds like a good buy...you cant put and heads on a Wee-Oh-Five that have big valves because of the smaller bore...the valves will hit the sides of the cylinder and that makes baby Jesus cry...
