I dont wanna turn this into a LS1 vs 4.6L thread, buuut
It is always funny when me and my chevy buddies get into a dicussion and I bring up the point that the 05 4.6L made the same HP stock as a ls1 that had 67cuin more displacement. they never have a comeback for that
the 4.6L has always made more HP per cubic inch than any of it's v8 counterparts.
