When I found out engine bottom end needed toe be rebuilt. I knew it was going to be expensive. After all, it's not like rebuilding a small block Chevy where you can basically do it for $1000, which includes replacing the pistons.
We need to bore the liners to the first overisize. That means replacing the pistons -- ouch.
The connecting rods need to be reconditioned and according to both David and the machine shop, it makes more sense to get new rods -- double ouch
David recently had these connecting rods rods made for a 330 engine and this is where I would get mine.
