From 225 to 375 depending on the configuration. The cylinder heads used on high performance engines (and some others of the era) were the 3782461X head with 1.94/1.50-inch valves. These heads had the commonly found double-hump shape on the end of the head. Milder engines had the inverted V head. It should be noted that beginning in '64 and through '68, cylinder heads with the double-hump shape also used 2.02-inch intake valves (aka fuelie heads). Castings with 2.02-inch intake valves were also used on the 365hp (Holley carburetion) and 375hp (Rochester fuel-injection) Corvette 327 engines.
Chevy didn't make a 350 engine in 2001
Chevrolet didn't make a I52 engine.
adding headers will allow engine to breath better and boost up horsepower but not by much, headers also make you vehicle louder with pipes.
Many factors determine how much horsepower an engine can produce. Give us the year, make and any other details about the engine.
Naming the exact make and year of engine is essential to this.
you stick another horse in your engine! silly!
350
I'm about 100% sure Chevy did not. The 360 engine was a ford engine.
230
no
It will have/make 150 horsepower @/when revved to 6000 RPM.
yes
