6.0 build
i have a friend that wants to build up a 5.3 or 6.0 for a turbo build for his regal. im trying to talk him into the 6.0, there only a bit more from the junkyard. my questions is, what could he build from either of those engines using the factor block. im an lt1 guy so im new to all of this... how big can you go with the 6.0 block? thanks for the help guys

he really doesnt have a set number, but the motor he picks up will most likely need to built up for the boost he wants to run, so i was just wondering the popular combinations for both of these engines? and how big can you go with the 6.0?

Lsx stuff will make quite a bit of power on a stock block + crank (any type).
6.0's will go to 408+ish cubes, but unless you know how much power you want to make OR CAN AFFORD to make, there usually isn't much reason to go bigger with the cubes.
turbo lsx stuff gets expensive fast. I know expensive to one person is pennies to another; but he should really define a use/horsepower goal. Then figure out what its going to cost to reliably meet that goal.
enough dribble, the good stuff is that a stock shortblock of either type (5.3-6.0) will make about 500-550 rwhp pretty easy. Some basic parts upgrades are needed, like valvesprings, pushrods, etc.
want more? change heads, or maybe pistons and rods, and intakes to make up to 8-900, maybe more. Guys have made a lot more, 1000+ for short term abuse.
really want reliability and big power? go high quality forged lower end, big$$$ heads, and a killer fuel system to make 1200+. I'd start thinking about an aftermarket block after the 8-900 range however. or maybe an ls3, they are a bit beefier.
costs escalate with the power. so pick a hp rage and go from there. If its a track car, what et's does it need to run? street? what type of fuel can you give it? LOTS OF VARIABLES HERE.
another example, my car made 550ishrwhp at 9psi and a safe tune for a long time. then with a switch to 6.0 heads was closer to 600 at times. Then a cam lobe failure made me tear into it and put in a built shortblock, custom cam, and dart heads. Im still figuring out the fuel system, and need it tuned but can make up to 700 rwhp on the right fuel. At that point Im out of turbo. 600 for street use is usually enough, I might run it up to 700 at the track a time or two to see what it runs, and then back it down to 550 again.

no on the trans,stock lq4s are already low compression.ive seen people make sick power on a completely stock lq4,with that being said id buy a lq4 put 700-750 through it with a PERFECT tune and a good fuel system it should last.if not buy another one for 600-800 bucks and build a 5k dollar stroker like your already talking about.thats my next combo.just my .02
