First of all I just got done installing a rear main seal in my lo3, while I had it out I checked my cylinder walls and I'm not really thinking it has much life left. So I'm thinking of building a 350 using the same stock tbi setup.

Is it possible to swap in a 350 (~260hp) while using the stock tbi?

Can I use any 350 block?

Annnd can I do all this without any chip burning because I know absolutey nothing about that.

Oh and if I decide to do this which heads would be better the 305 heads or 350 heads?

 

Spend a few minutes of your time searching on this matter. There are even some thread allready started in this forum on this matter. This gets aksed an awfull lot and I am positive you will find your answer with a few searches. This is a very common swap and it is covered in great detail already in the archives of this site. Because I know you will find your answer, I will shut this one down to reduce redundent topics. Good luck and happy modding.
