There is a reason it is so cheap. Anything will fit with the right hammer. NO it is not worth it.

Just keep an eye out. Something will turn up. Are you looking for performance or just a pontiac engine?

Heres the scenario we (my dad and i )have our original numbers matching motor in the car we want to haul and rebuild and not beat on that block so hard. so i wanted to get another motor build it up make it have some good power and put that in the car to drive the car with that motor and no worries of damaging the original block and well have a another motor that has some more power.

Buy the motor Eric has listed, if you want to hear what it will run like look in BearGFR's garage....thats a sweet deal with all the best "goFast" parts in it. If you put in anything but a Pontiac you will have to modify the car from original and then un-modify it to put the original motor back in. Where are you located i will keep an eye out for Pontiac blocks in your area. Have a few i might be letting go of soon...will post here first if i do.

A 403 Olds is not a performance oriented motor. Definite boat anchor. Not even a consideration. A Pontiac 326 or 350 would be a huge step up over one. Put a Pontiac 400 in your '67 GTO.
