Ok i have a mild built all motor ls set up rite now with crower 404's and i was wondering if i switch the pistons out to say a 10:1 and then boost will i be able to keep the 404's

 

no sense in "fixin it" if it aint broken.

 

x2

 

well i wanna go turbo so this is y im asking

 

People have great success with the 404 from what i read but according to them the idle is a bit choppy and a set of cam gear is helpful

BTW, anyone have experience with crower 403? i have that and will be running it on my LS set-up and wonder how it would be like

 

404's on boost are great, takes a lil longer 2 spool (4-500 rpms) but the top end is well worth it. U might want 2 think about a lil lower than 10.5:1 I have srp 8.5:1 took a little longer to tune but makes the boost guage look pretty.
