73 Duster 318

My budget for the engine is $1600 for parts. I'll be doin the work myself. I'm not a beginner, however I'm not highly experienced. Its goin to be my daily driver and maybe takin it to the track every now and then. The engine is sitting stock. I have a Weian manifold and Holley 1850 carb that I'll install in a week or so. I threw a glass pack on there because I needed some extra noise. I'm still unsure of the exhaust I want.

I need tires too. Anybody have a Duster with 18's? or Whats the biggest tire I can throw on the back without modification?

I've owned Toyotas before this and still do. This way different from my MR-2 and SC300.
