1969 400 Pistons

Sonic test the block. If it will bore to 4.00 you can use 327 Chevy pistons after bushing the rods down to.927" If you pick wisely, they will save a couple hundred grams (easier on rods and bearings), give you rings with less tendency to flutteriing (1/8 vs 5/64), and remove the pin offset. Don't deck the block until you see how far they are below deck.
