i was thinking of just a 3.25 or 3.3 with all 3 options except the ssic i wouldnt do 3.25 is this right oh and i dont have a tune but i do have a ls1m scanner

maybe 3.2, 3.25.

Really comes down to how the car likes it and how the tune is.

if i did get a tune it would have to be canned no one has a tuner around here

I think you will be able to run a 3.2 with those mods pretty comfortably. Some guys are even able to get down to a 3.0 but would be running less timing and mostly not worth it.

The above is with a custom tune. With a canned tune it's kinda up in the air but some guys on here or other forums could get you pretty close if you have a wideband and some way of seeing KR.
