The cylinderpressure issue.. keep down the boost at torqe peak and boost up at higher rpm.

 

I just don't want the motor to be working as hard. Less boost. My tuner has already described the above, less boost at peak torque etc. See how it works. Regardless, many people have had issues around that power level with 4 bolt heads.

 

Those EFR Borg turbos are bad ***. I have used them on a couple builds and been impressed! While a little longer, they greatly simplify piping! Integrated BOV is nice.

 

Those pyramid head gaskets might help u as well, and then some block filler

 

id fill the block keep water flowing through the heads. arp rod bolts and 1/2 inch head studs. good heads cam see where it goes lol

 

I got filled LSX block if you are interested, that should get ya to where you need to go.

 

Updates???

 

He's still day dreaming. Engine Dyno and in a car are two way different applications. Twin 6766 Precisions or 366 Borgs on a 5.3 with head studs and gaskets, cam, valve springs and pushrods is the way to go. No reason to give up power/torque with the shorter stroke.

 

If u can't control boost at peak tq, one could dial timing back a bit at peak tq as well.

 

This is true! Use to go through head gaskets like crazy!

 

I got a 2000 Silverado 1500 came with a gen3 4.8 lr4 ls it’s an iron block, flat top pistons, aluminum 862 heads im putting twin GT35 GT3582 with a stag 2 sloppy cam 3000 stall, torque converter everything forged, pistons rods, crank stock bore 3.780 I’ll make close to 800hp if I’m lucky
