hmmm...
Completely stock 3800 series II or III vs a '96+ 3400 with revised intake gaskets and bolting procedures (for those "bulletproof" 3800 fans out there, this evens it up a bit) with a 62mm throttle body

I know it's unfair, but in this particular arena, it seems an interesting match

The 3800's are all iron (block and heads) and 90*
3400's have aluminum heads with a smaller, 60* block

How close would the 3400 be to the 3800 in terms of power to weight ratios?
