4 Bolt Build!! 5.3 block 383cu.in
3.905" bore
4" stroke
317 heads
ARP head and main studs
LS9 gaskets
ls1 intake and throttle body
th400
spec'd cam
s480 96mm/1.32
truck manifolds
divided 2 1/4" crossover
e85
Megasquirt with MS3X board.
Looking for tips to make this thing last under boost and how to keep the heads sealed. Don't really want to mess with o-ring block. Its a semi budget build. looking to make as much power as I can and keep it together. Would it create less cylinder pressure and be better for sealing if I turn say 7000-8000rpm? Is this reliable with my setup. I pushed my stock londblock LS1 to 6900 on the bottle without any issues. the motor will only be on 8-10psi 75% of the time. Would hope for around 1000whp around 20psi. Is this doable?

I see a lot of guys on here running your normal head stud and ls9 head gaskets without any issues. Im running ls9's and AES ported 317 heads with ARP head studs and plan on making 22psi.

You need to look at peak torque that is where your head gasket failures happen. In the grand scheme of things you would pull timing until you are past that threshold then add timing back in above it if it likes it.
