Default 5.3L Chamber and piston questions

Is the sticky up top correct in being 61cc stock cc for a 5.3L?

And also, -2cc valve reliefs are about how deep, as in clearance wise, .100" ?

Thanks,

Charlie

yes stock chambered 5.3's are 61cc, however most ported ones end up a bit bigger due to unshrouding. they come in at 62-63.

Well, that added little unshrouding will be helpful then, looking at possibly having 12.5:1 cr, at least until the new heads come in later in the year.

*scratching head* You dont think it will make a good boulevard bruiser and strip monster? Sure, reduce some timing, mix some race gas, or xylene, for each tank right
