National seabreeze 8341

Yes, 600 hundred pounds for torque is very limited for an Allison five speed compared to most six speeds behind the big blocks. As Passin Thru points out, you cannot turn up the 5.9 with a 5 speed for that reason.

Called limited because you couldn't turn if up to 600 hp due to the Allison not withstanding 1450ft/lb torque.

NRV made a Seabreeze Bus in 01-02. It was on a Spartan chassis but I do not recall it with a 300. They were the isb 5.9 rated at either 260 or 275 and the five speed transmission which has a very limited torque rating. I had saved a copy of NRV pages but it no longer opens and a goggle search did not bring anything up. Used to bring up all NRV motorhome specs. Working from an old man's memory here. Hope somebody can help answer your question too.

It is 605 ft lbs of torque if you call that very limited. However that was for the Allison 3000 6 speed maybe less torque for the 5
