seeking build advice so as a spin off from this thread: https://ls1tech.com/forums/generatio...lled-53cc.html
it has come to my attention that this build may not be "ideal."
so im asking you guys, what do i need to change to make it more efficient?
---------------------------------------------------------------
here is the info on whats in the engine:
383 short block K1 rotating assembly.
K1 crank 4.000 4340 crank.
K1 6.125 Forged H beams
Wiseco -32cc forged pistons.
Comp cam hydro roller lifters
With 64cc head motor would be 9.4-9.5 or so on comp ratio
LS6 243 Ported heads
New valve job.
Titanium retainers
Milled to a 53cc
2.055/1.6 stainless valves.
Manley valve springs good to .650
631/631 240/244 lobe center 111
-----------------------------------------------------------
now the engine is complete, minus pushrods and rockers. thats kinda of where this build left off, and now i am taking possession of it.
im perfectly fine changing things up. have it be getting a different set of pistons, a different set of heads ect...
i plan on running the engine N/A.. maybe with n2o at some point, but primarily a driver on pump gas.

there were a few comments that made me ask these questions in the previous thread.
well it will work to drive NA, I would definately go with a smaller cam though 23x/24x .600, otherwise its not gonna make anything down low. just dont expect to make huge power with it. Not to mention anything over .600 lift there is no way you will have enough piston to valve clearance
that is an absolutely terrible setup, sorry but its not gonna make near the power it should. Why the huge dished piston then small chamber heads?? compression with those heads on it will be 9.4 unless you have a typo with the piston dish.
valves are gonna be shrouded to death
and that cam is entirely too big for that setup
