273, or 318?

From the little research that I've done, 273 pistons are more costly than the other sbm's and they usually have to be ordered.
Well may be. Egge had mine on the shelf. The engine was only made for 6 years and of course you can't get pistons at Wal Mart like you can 318 slugs. The L2222 pistons for the 273 are $637 a set from Egge. The Keith Black KB176's from Summit for the 318 are $485 a set. Yes they are $150 more a set.
