Engine Builders I Need Advice Please, Step in.
Engine Builders I Need Advice Please, Step in. Here is what I have:
2005 383 Forged 5.3 10.5:1 CR short block with 5 cc valve reliefs
3.905 bore
4.0 stroke
LS6 heads, milled to 58 cc, sodium filled valves, stock sizes.
I would use a .053 head gasket?
I am looking at around 11.5:1 CR? Is this too high on 93 octane?
I would like to throw two stages of dry nitrous 75 shots at 3500 and 4800?
Injectors are LS2, LS6 intake and ported TB.
I have a cam reccomendation from an experienced person of 244-248 114 LSA
(Currently have a comp cam 232-236 115+3)
Should I take the combustion chambers to 62 cc?
Go larger stainless valves?
Or just do a little home porting and leave the chambers alone?
Also, with the 2005 5.3 block and the LS6 heads, what specs do I use for getting gaskets, ARP head bolts etc, LS1 or the 5.3?
Experienced thoughts and opinions are welcomed.
On a side note, economics is a consideration. But I believe things can be accomplished.
Thanks in advance.
