Well the most recent 312 that I acquired should be resleeved on all 8 cylinders.
It is original bore size but too far gone for allowable boring.
My normal machinest is not a fan of sleeves (neither am I).
The folks who dipped the engine (Chemstrip) suggest speaking to another machine shop who resleeves engines all the time.There position is that most new engines are sleeved design and that sleeves are O.K.
I"m just looking for opinions on needing a single sleeve or also multiple sleeving on the Y Block engine.
I"m NOT gonna sleeve this block as I have a few more 312s to explore to find a useable core.
Tell me what you think.
