GM tried twice to solve the crank harmonics which exist from 6400 to 7100/7200 rpm - avoid this operating region. For race engines accelerate through this rev range as fast as possible and ensure gear changes maintain the rpm following the shift above 7200.That's the forum devoted to converting this engine into a hot road muscle turbo car
Due to the light weight valve train the engine has no problems being spun hard if you take care of the valve springs, balancer oil system AND RUN A FULLY counter weighted crank
The black opel ran its 4200 as hard as 9300 one year - the sound was awesome.
Test run of the engine Turbo charged vid
the stock engine produced 270-290ish hp depending on the year, 350hp jump is minuscule... one could easily get that from getting rid of the factory pcu and going aftermarket...https://www.theturboforums.com/threads/vortec-4200-l6-turbo-build.372350/
Another forum!
The I6 version was used in a Baja 1000 racing truck, winning its first race in a class that also included V8 engines. Another I6-powered truck won the truck class at the Pikes Peak International Hillclimb. The I6 Atlas engines were produced at the Flint Engine South plant in Flint, Michigan,
Length wise its within 1/2" of a 250
Its as tall as a 292
its wider
the 4200 oil pan selections are slim and cause interference in many vehicles (center link, steering).
LOVE the sound of a straight six!Turbo charged "air ride" of the engine - youtube

He's now getting over 1000HP with the boost! [oops that was the bigger 5.3 liter engine] The car and engine are going to be featured in an upcoming issue of Hotrod. https://www.inliners.org/ubbthreads/ubbthreads.php?ubb=showflat&Number=24329https://www.hotrod.com/articles/ccrp-1108-turbocharged-vortec-inline-six/
With a turbocharger and some tuning, this simple GM SOHC inliner is now making 470 flywheel horsepower and 450 lb-ft of torque with a mild 8 psi of boost while limiting the factory rotating assembly to just 5,800 rpm. Wieser attributes much of the reliable power results to tuning by Mark Romans, who used his HPTuners software to dial in the spark and fuel. Wieser thinks he can squeeze 10 pounds of boost out of the turbo to make 500 hp, but he also has plans for a new, more aggressive 4200 with forged pistons, aftermarket rods, and a later '07 head that will allow him to punch the power up to perhaps 600 hp with 14 to 15 psi.
