can’t know without cc of your combustion chambers, head gasket thickness and deck height.

Lsp Przy

The deck height very little is being taken. More say just even it up make it even and flat.. the heads should be 54.5 whatever stocks heads. The gasket I want keep this car around 8.8 to 9.0 as it will be running 16 pounds of boost


Sto I remember what deck height will be I know it will be hard to say

According to this calculator with a stock deck height you'd be right around 9:1 with a .040 head gasket:

9.1 isnt high, I run 9.4.1 with LT4 heads and at 12lbs of boost my motor makes 806HP...

Lsp Przy

The piston I got are rated at 20 pounds they are diamond blow through pistons i got them gapped at 16 that's the reason why I want it little lower then 9.0 just for peace of mind plus it's going be street /strip car still running intercooled and stage 2 snow system oil cooler. Rated at 650 HP 160 pound injectors

I just need to know a good vavle size to go with
My t56 will probably blow up. But will worry about that when it does
500+ fuel pump

Also what what supercharger crank dampener I called ATI

Heads/cam 396. Nothing special.
Keep your quench as tight as possible. If you are wanting less CR then use a different piston or get the chambers worked over.
And yeah, this ******' guy knows some ****.

Lsp Przy

Yea I'm talking to Loyd on his trick flow heads ported for stroker blower app let him do the cam too

I have 1.7 rockers scropion hopefully Loyd can put the heads and bigger vavles where I like it

With that much boost, I would do a 383ci (maybe even a 355) before going with a 396ci.

But that's just me.

I had a budget cast boosted 383 that went 137+mph in the 1/4 at 3850lb with stock (cleaned casting flash) heads with stock sized Manley valves. I was told a good 5 angle valve job was as important as valve size.
I'd just let Loyd decide. He is a master.
