Getting ready to rebuild the engine in the CJ2A....Its the numbers matching block, was told it already 60 over and so I looked into sleeving engine
The shop I want to use told me 500 labor to sleeve the engine and do all machine work required
He said he would sonic test the block but felt there is enough iron in these blocks to go 80 over, he is the second shop to tell me that
Currently with a new radiator and 160 degree thermostat even in 90 plus degree days the jeep runs very cool

Whats the general thoughts on this and thanks for advise
