Compression Ratio and what camshaft?
#21
@Gumby83 as mentioned by another member, a new GM crate LS3 maybe worth considering. The LS3 is a cam swap & valve springs away from ~550 flywheel ~475 whp. Even ~500whp is within reach with a rod mod'd LS3 intake and a few other tweaks. Chevrolet Performance LS3 430 HP Long Block Crate Engines 19432422.
Also available with intake, fuel rail, injectors, coil packs, water pump, TB etc.
Compression is 10.7 and folks boost stock compression LS3's on a regular basis. However, all my set ups are NA. Hopefully the boost commentary will be from the folks that have experience boosted LS set ups.
Of course a lot depends on desired power goals and intended use etc.

Listen. Get a full rebuild kit on ws6store. Max effort ws6store rocker arms. Ditch the tfs heads. Port the stockers. Tfs is wayyyy overpriced for that as cast junk. Summit ghost cam. You don't need a cam degree tool. Engine is out, put it at TDC and line dot to dot. Ditch the timing set and just get a new ls2 chain. Paint oem valve covers, aftermarket stuff always leaks. Timing cover alignment tool? Lol who needs that? BTR gaskets are overpriced. Felpros will do. I probably just cut the cart in half and now you have money to spend on things that actually help.

Before you order any rotating assembly please have your block checked first. I’m sure you will need a .005 cleanup and then you need to order the right size piston for the clean up job or if you plan on punching it out .020-.030. Figure this out first. If you are not stroking maybe just look into rods and pistons. Guys boost the hell out of stock cranks if you plan on keeping close to stock cubes.
