....I'm going to have lots of questions.
I recently bought a Grand National and was told "the engine was making noise, so we shut it off and pulled it out". That was as far as they got. I went in assuming the worst but hoping it was just something in the heads. Turns out it's a spun bearing, #5? rear most rod. And damage to the piston. Looks like a crank clearance issue because there was not much left of the bearing.
I plan on using a new crank and different cam (mild roller). I'm not building a monster.
Do these pistons look stock? I'm assuming so. I'm going to need a good stock rod and piston.
All six cylinder bores look good, no obvious damage. Once the block is stripped it's going to the machine/engine shop for whatever they can do, not sure the extent of their services. I'll be happy to get back an assembled short block and rebuilt heads.
