need help deciding a motor

okay

here is my situation. im beginning my resto but its not looking like it will be too long of a process. eventually i would like to go with a 5.7L or 6.1L sitting in an alter-ktion k member.

the price of those means i will have to save a while to get it and that setup is a luxury so im thinking if i get the car all fixed up and ready i might just put in a different motor for the time being. I have a few options.


1. I have a 273 in my parts car that is unknown as far as condition.

2. 318 bored over .030 that is sitting on an engine stand. needs pistons, and possibly 2 4bbls to top it and few small things (gasket kit, piston rings and that stuff).

3. I could buy a 400 ci from my brother who is using a 360 in his duster drag car

4. just wait and get what i want

tell me your opinion.
