OK so I've been posting up alot of different combo questions lately because I have been collecting multiple setups. I was gonna run an ls7 but now I think I'm gonna go iron block so I can run a bigger shot. Also i dont mind a fairely large camshaft but something that isnt gonna be impossible to tune
So here's what I have-
6.0l block yet to be bored
Lunati pro billet rods 6.125"
Lunati pro forged crank 4.00"
LSA heads that are going to wcch for their cnc treatment should flow around 350cfm
Arp head studs
Arp main studs
FAST 102 big mouth throttle body
Still need-
Pistons- any off the shelfs up to the task?
Holley hi ram
Custom cam
Injectors
and lots of little stuff
Now I have some questions-
What kind of pistons would you guys suggest that will handle around 20psi What kind of rpm should I expect this thing to turn
What kind of compression can I get away with on an intercooled e85 setup
Does the block need to have the mains doweled
Is there really a risk of piston rock when using a 4.000" stroke
Sorry for all the questions and thanks for any help- Nick

I'd bore it to ls3 specs (4.065) and use wiseco pistons. This would net you close to 416 cubes.
Just watch as with the 4 inch crank, the pistons tend to rock in the bottom of the bore causing ring seal issues.
Another option to avoid this is look into a 3.9 inch crank. This would net you 405 cubes and make killer torque under boost and keep the pistons stable in the bore.

Car will be on spray no boost and I already have the crank. Hopefully there is no issue
EDIT- car is gonna see boost, decided against the nitrous idea
