Hi I am building an l92 for boost and was wondering can I push 700whp l92 heads? I plan on getting scat rods weisco Pistons and run a stock crank with main studs. What Pistons should I get for boost?

Is the L92 still together? If so, leave it together and add boost.

It is torn apart because of a bad lifter, I am getting lifter bores machined and bushes as I had some damage

I heard the l92 heads have a thin deck and will start to float?

Let me redirect you to this EXACT same post you made last month.

Yeah but I have been reading that the factory heads have a thin deck that floats

JoeNova

Stop reading so much.

I've taken my L92 heads and factory LS3 intake to 28lbs on MANY occasions. They are no different than a 799/243/806/823 castings. The only "thick deck" factory heads are the LSA.

Square your tune up and let it eat. 700whp is a joke for a good running L92 motor.

Appreciate it, I tend to be a book worm.

It's better than the opposite that's for sure.

So just an update, the Pistons have some ware on then so I can going to replace them primarily as I found a good set of Mahle Pistons, L92314070F05 there specs are L92/LS3 Chevy PowerPak Piston & Ring Kit

• Forged 4032 High Silicon Aluminum Alloy
• Bore: 4.070"
• Pin Diameter: 0.927"
• -4cc Dome Volume
• Compression Ratio @70cc: 10.1:1

Will these Pistons help in making the power I want as compression is lower, I don't know a whole lot about compression numbers.
Thanks

10.1 is the most compression I would use on a FI motor. Those Pistons will work.

Could I further lower compression with a thicker head gasket?

Yes. Run ls9 gaskets and head studs. Might as well install bigger valve springs while heads are off.

Ok , will do

Ok thanks
