good luck on your water test ! been messing with LS stuff for long time, currant build twin turbo 6.0 in 19 eliminator Daytona jet. I have talked with others doing LS swaps and many have had revision issues, some engines with very little cam seem to, I think you may be into issues with those exhaust(hope I'm wrong) but running dry to the tips may be only way on many of these engines...

Almost makes me want to order a custom ground cam in standard chevy firing order and just swap wires to correct coils and give it a test. Still possible being carbed.

Bad thing about those is, I don't see how you would be able to make them dry. Like ezstriper said, almost every successful LS swap I have come across that has any kind of cam at all has dry exhaust.

SB, I really like your idea of 2-into-1 exhaust, if for no other reason than it would sound nasty!!!!

I have two things to add to this thread
1:

2: LS vs BBC weights

A couple years ago a buddy weighed several shortblocks for fun.
Same day, same scale

LS1 = 180 lbs
LC9 = 200 lbs
LY6 = 310 lbs
393 stroker LS = 310 lbs
540 BBC dart iron block = 360 lbs
