Time for new engine

After having lots of fun the first part of racing season, it all started going down hill in July. I developed an internal water leak. First time around new head gaskets and a dose of block sealer cured it for 5 weeks. Then it happened again, more water. Tore it apart again and pressure checked the heads, put it back together and ran another couple of weeks. Leaked again. This time there was no stopping it.

Dragracer interuptus.

Last week I tore it all down and pressure checked the block. In cylinder 6, I could see a little tiny bubble form. So, I got a pin and poked it. The pin went through the cylinder wall! Clean through! In all I had 3 cylinders with holes. ](*,)

The moral of the story? Don't bore a 72 440 +.060. I had a friend I used to race with that had the same thing happen years ago, so i called him and he still had his junk block. Both blocks were +.060, both blocks were '72, they were cast 4 months apart. Both ended up with pinholes in multiple cylinders. Coincedence?

The plus side is I have been wanting to make more power, just not this soon. Time to get busy, spring is coming.
