in need of a 427 block...recommendations

[69Tom]

As I had to sell my block for financial reasons, I now am in the market for a block to build an L72 motor. This is not a number's matching car. I do, however, have the correct intake, heads, crank, cam, rods, pistons, lifters for a 1969 L72. I pretty much just need the block.

I have a couple questions:

1) I am on a very tight budget, so the less $ I spend on the block, the better. What block would you recommend? I will not be racing this car. Just mainly for pure enjoyment and driving about. I've been looking for 3963512 blocks, but all I see are quite expensive.

2) While I figure it depends on the wear of them, am I able to use my original L72 TRW pistons? Or is it ill advised, even if I'm able to find a standard bore block due to the inevitable wear (even if slight) they've received?

If it matters, this is going into my 1969 Biscayne. I'm also open to trades--all my L72 stuff for a mostly complete L36. however, I know the L36's are going for quite a bit of $ not too, so not sure if that's even realistic given my financial constraints.

Anyway, thanks for the help.
