Well my car has been down for almost 2 years now since snapping the crank and I finally have the funds to put the motor back together. I have pretty much all the components to build the motor but I'm nervous about getting the block machined right. The block going to the shop is from the reman. motor I had in my car and I want to make sure it's still usable after being machined once already.
The pistons I got from DD are .030 over, the pistons that were in the motor were .030 over. The reman. motor broke with only 15k on it so I don't think the cylinder walls saw much wear, but there wasn't cross-hatching present. Could this be a problem? I also already have rings for those pistons (once again supplied by DD.)
The pistons are made for a 9.225" deck height. Stock is 9.232". I also have MLS gaskets. I'm worried the machining for the gaskets would make the deck too short. Is this something I have to worry about with a higher than stock compression ratio?
I already have crank bearings and a 4.2 crank but the block has probably already been line honed when it was rebuilt. Will my bearings not fit if this is the case?
As long as none of this stuff is a problem the block is going out next week. Can you guys provide some insight on these potential problems? I am planning on doing assembly myself (with help from my dad who is an ASE master tech and gearhead but knows nothing about SCs)
Thanks for reading.
