5.3L set up for turbo good? long story short ive had a low CR forged 347 in my car for the last few months, i get my turbo kit in and fuel system in about 2 weeks, planned on being done with car and getting SD tuned, well this week it spun a rod or main bearing (havnt gotten that far yet but not upper end at all) at this point with my money situation im probably going to just buy a $500 junkyard 5.3, put my whole top end on it (heads cam, push rods, studs etc) i plan on running this engine for awhile maybe leave it in if im happy with it, while i figure out what im doing with my current engine.
basically more or less i wanna know what yall think of this engine build and or would it all work together (piston to valve clearance. etc) as i havnt done much research on this yet but some and i kinda need my car back on the road soon, plan on grabbin the first decent $500-600 5.3 i can
-5.3L stock short block
-243 heads stock with .700 lift double valve springs
-7.400 comp cams pushrods
-ls7 lifters
-brute speed blower cam
-double roller timing chain
-high volume oil pump
-ARP 12 point head studs
-ls9 7 layer head gaskets
-E85 on twin pump hobbs switch ran

Verdad Gallardo Ls1tech myth #137: you need to buy aftermarket rod bolts.
If you wanna waste your money, just give it to me so I can buy a cam from Martin. Don't bother with rod bolts, people touch 7,000 RPMs all the time with stock rod bolts. I've ripped wrist pins out and the rod bolts weren't stretched.

almost mimic of my build. i went with a cam from Martin and the KMJ studs. Pick up a LS3/4 oil pump and a stock LS2 chain and you will be fine.
Martin spec'd mine for 6500 redline, and my power goals are in the 650 range. Martin keeps telling me I am selling myself short.

With a new setup, start low with the 8lb. Most people use the lowest spring they can get and use a boost controller to add more boost above that springs rating. Ex: with an 8lb spring, you can add 4lbs of pressure to the back of the gate with a controller to get a total of 12lbs boost. You can never adjust to less boost than the spring rating though.
