We are actually pretty much in agreement. If the weight of this 43' Ventana "fully loaded" is no more than 35k, then a 380hp ISC (particularly if you have one of the rare" ones equipped with a 2stage engine brake) then your HP/ weight ratio is on the money.
However, what happens....
1) When you hook-up +5K of toad?
2) If the fully loaded weight( before toad) is +40k?
3) If you don't have the 2stage brake?
Don't get me wrong...I love my ISC...just wouldn't want this engine in a +40k rig with a single stage compression brake. Regardless, my bad for assuming loaded weight & exhaust brake....really need more info from the OP.
