Im not sure the maximum but I think you can bore out to at least 361.
If it's not cracked and is still stock bore, About $ 125.00
Just get a 4 bolt main. Don't fool with a "conversion".I don't know what labor is worth in your area, but there's several hours of work to line bore and hone a block, plus the cost of new main caps. Probably at least $400-$500.
2 bolt or 4 bolt main?? is it stock??
Crate engines can provide power to any type of car. A crate engine is very powerful. A crate engine is much more powerful than a regular engine as it produces much more horsepower.
As much as you like if you can afford it when it breaks
The weight of a milk crate varies from between four to ten pounds, depending on the size of the crate and the material it was made from.

Actually this engine isn't worth very much unless it has an original 302 crank in it and it is a 4 bolt main, this casting number was a very common one and was used for the z-28 like the previous poster said however it was also used for 2 and 4 bolt 327's and 2 and 4 bolt 350's the only main difference is the crank and main caps, it probably is a high nickle block however making it pretty good for performance. it is not however a 305 since these came factory with 4 inch bores(305 is 3.736 inch bore)
