where would be the best place to pick this up and how much is it for just the block and i'll swap everything from my 305 onto it for now until i get more money for better upgrades

 

Junkyard. Although, most anything from the yard will probably require some form of machine work. Most machine shops will probably sell you ready to go blocks which will be fresh and ready to go.

What exactly do you plan on swapping over? Not everything is compatable.

 

you ought to be able to find a builder 350 for 100 to 300, at least around where i live you can. 305 pieces won't work in a 350 balance will be differant.

 

i will transfer what is transferable. not sure what yet though. What can be used and what needs to be replaced? and a rough geuss on price of complete swap asuming i do all the installs?

 

You got some research cut out for you then if you don't know yet. Try a search for 305 to 350 swap and see what it comes up with. I just did that swap, and I ended up not really using anything except accessories to swap over. I found an LT1 crank and LT1 PM rods for cheap, got some TRW pistons, a 350 balancer and flexplate and called it a day. You can use the 305 heads, but they will choke it down badly, and a different cam obviously.

 

that is the way to go for a budget. the lt1 bottom end are stronger.try to get a roller block if you can. heres a link to some parts for you.. good luck

used lt1 parts

 

just a pointer be sure to match your parts its crucial. research research research.
