Officially back by popular demand, https://speedonthewater.com/in-the-n...700-sci-engine.

I wish they would bring back the 525 !!!!!!

Does that mean the NXT is coming back as well or all 700's will be paired with a trans/M6?

The return of the Donzi ZRC and brand new 700's with 6's, now we're talking !!!

Odd they didn't give it a 50 HP bump or something to make it "special"

Was the 860 a flop or just too expensive? Odd they mentioned it at a Nortech even when Nortech is primarily an OB builder these days. I would have thought Cig would have gotten the chance to re-introduce the new motor.

Second that. Not that I'm in need right now. Have mine out and completely torn down right now for a freshening. Started as the top end deal but decided to take them all the way since they were out. 12 years of flawless service, oil, filters and one plug change, they show no problems internally. These have got to be the top of Merc Racing's best ever list, these have been worth every penny.

with better valve train components

Besides the lack of headers, what’s wrong with the 520? What about the 540?

Exhaust systems with cat converters and such.

Someone know the Donald and have'm call the EPA

I guess these would blow up stock bravos? Are they like 525 fwc?
