Gary and Vetteoz are completely correct, but depending on your overall goals, you may not necessarily need to restrict yourself to just that motor. Are you looking for a motor that you can just swap in, slap an intake & carb on and use? If so, then I agree with their suggestion 100%. However, if you're going to rebuild the motor you get, and especially if you're going to use different and/or aftermarket heads, your options for a starting point open up a lot wider, mainly to ANY 350 that is roller-cam ready.

 

Please be aware that not all 880 blocks are fully machined for a mechanical fuel pump, some have no coolant bypass hole at the pump and some don't make nice with several aftermarket timing covers.

 

Whatever you buy make sure you get it machined and checked out before you go throwing parts at it

 

Going to buy one and rebuild it and then put in just don't want to meany problems trying to put it in

 

It is just another SBC , identical to the 305 you have now and fits exactly the same.

 

buy something with the "LS" series engine,swap everything over.you will be happy

 

For got one tinnie winnie detail with a LSx swap.$$$$$$$$$$$$$$$$$$ Yep that's it.
