There’s no shortage of top-shelf performance applications these days, with power and torque figures that were deemed unthinkable just a few decades ago now prowling the streets and tracks en masse. Naturally, in an environment like this, it takes a lot to stand out, but Katech has plenty to offer, including its new Track Attack LT5 Chevy small block crate engine.
For those who may be unaware, Katech has made a name for itself building high-performance engines for motorsport and the aftermarket, with history that dates back four decades. Past successes include engines for the GM Corvette Racing team, as well as wins at some of the most famous tracks around the world.
Now, Katech is showing off this new Chevy small block, fittingly dubbed the Time Attack LT5. Based on the supercharged 6.2L V8 LT5 from the C7-generation Chevrolet Corvette ZR1, this lump-of-go was tuned and tweaked to lay down a mind-bending 1,159 horsepower and 1,063 pound-feet of torque. Compared to the factory tune, which is rated at 755 horsepower and 715 pound-feet of torque, that’s a gain of 404 ponies and 348 pound-feet.
LT1 pictured here.
To make it all possible, the Chevy small block got a slight bump in displacement and compression, now sitting at 388 cubic inches 10.3:1, respectively. The cylinder head was CNC-ported and there are new competition valves, while Diamond Pistons beef up the internals.
Customers can choose between two different supercharger configurations, including a CNC-port job for the factory LT5 blower, or the Magnuson TBVS 2650 supercharger.
Katech has yet to provide pricing info, but it is likely to be rather expensive. Still, for four-figure output from a company like Katech, it could be worth it.

The drag strip is the only place that one could safely exploit that kind of power as it’s too much for a road course.
The real question is what 2020 or 2021 Chevrolet vehicle will be the first to undergo this Frankenstein surgery as it is doubtful it can fit in a C8 Corvette and reason why no one has yet built a kit, but one can imagine a Suburban or Cadillac Escalade undergoing such an upgrade as it would totally transform the personality of the vehicles.
It would be a nice C8 option for those who can afford it and use it responsibly.
Drop that into a short bed standard cab…
Wow
Hey what about bring the 2 door tahoe back with the new Lt5 with 3″ drop an wide tires.
Bone stock body 66 or 67 nova with a 4 speed
Put it in my 2014 Chevy SS
The next step has got to be AWD, the engines have overwhelmed the rear wheel drive systems. Be honest, the cost of that crate engine you could probably lease the Porsche Taycan for two years, and beat the guy that bought the crate engine no matter what he put it in.
Put it in my 2012 Impala LTZ. Perfect body balance to cradle that beast.
Drop that into my 2016 Silverado ltz, hook it up to my 8 speed auto tyranny. 755hp would be fun to run in my state, lots of open country.
I would like to see that in my 83′ Firebird😁
Would this engine be possible in my 2005 vette coupe?
I have a 2005 SSR that would be heavy enough to really use some of that power. What an awesome machine that would be.
How about taking up a company challenge, do a ZL11LE package and go for -6.00:00?
Bring it Katech, you would get way more media exposure then with just an engine X, Y, or Z HP spec if you were able to hammer down a record lap time!
800-850HP with a higher RPM HP curve/redline? The 1LE’s down force limited it’s top speed on the long straights. It should be within reach.
