Engine builders...this machining cost sound excessive?
Around here bore/hone is around $180 on a V8. Sleeving is $100 first hole $80 after that per hole plus sleeve. Deck paralell to crank $80-90. $160-180 for a five angle valve job. Balance is around $200. Head resurface $40.
Just sample prices from the shops I use today.
My last Hemi build took $1500-1800 for everything...line hone, bore, hone, deck block, resurface heads, valve job, five sleeves...might be more don't remember,
