Default quick question...lt1 less than 350 cid or less?

title edit: lt1 350 cid or less?

I know its been beat to death a million times but i just need a quick answer...I know an ls1 is 346 and I coulda swore an lt1 was a 3xx but NOT a 350.

Again, I know this is done and done again, but I cant seem to find any threads using the search button so please forgive...

This is what i came up with on my own from my own calculation but i could be completely wrong.

LT1's 350ci
Bore: 4.00" Stroke: 3.48"

LS1's 346ci
Bore: 3.89" Stroke: 3.62"

difference in Bore: 0.11"
difference in Stroke: 0.14"

0.14" - 0.11" = 0.03"

Total 0.03" - 350ci = 346ci

If someone knows better please correct me.

I have no idea what you are trying to do with your math.

For displacement 4.0 X pie X 3.48 X 8 = 349.85 ci

Let's do some math...yay!

[(3.1415*2"*2")*3.48]*8 = 349.84 in^3.

Epic math fail above.
