Mercury Racing's QC4v - ZR-1 Net Registry Forums

Marc Haibeck · 12-29-2013

Mercury Marine is marketing an engine that looks to me like a big block LT5. They have it rated at 1650 hp in the twin turbo configuration. Of course it can be run as a normally aspirated 540 ci engine. At the SEMA and PRI motorsports shows they had it on display as an engine looking for a car.

They refer to the LT5 as their inspiration for the QC4v. Indeed the cam drives look like the LT5, including the double row chains. The cylinder heads and the plenum are similar to the 475 hp ’95 LT5 that was cancelled by GM. The injector housings are integrated into the cylinder heads like the ’95 475 hp LT5.

Click on their SEMA brochure for more details.

It’s nice to see that they have given the LT5 the recognition that it deserves.

Now, what car can this huge engine can be fitted to?
