As said above, stock springs are just barely good enough for stock lift....even if GM only saves a dollar or two on lower quality springs per car, it adds up quick to a every large savings per year.
As for cam, I'm running my ported/ milled 241's with dual valve springs and a 255/263 .624/.624 115lsa

Does your shortblock have anything upgraded besides the cam?
What's your thoughts on street manners, hp &tq and overall impression of that cam?
Stock intake?

No where near stock lol. 408 stroker, 12.5:1 compression on pump gas, fully forged with fuel cutoff set st 8,000 rpm. I'm running a ported Edelbrock proflo xt and 60lb injectors.
In my stock cube 346 I ran and liked a 238/242 112lsa cam....it was a cold bitchy setup, but in my opinion streetable

I have a set of 241 heads and am going to use them on a 5.3 with flat tops, mild cam and either a ls1 or ls6 intake. I really want a decent street motor made of factory parts. Nothing crazy, just fun.

For your 5.3 I'd go with the ls6 intake, a good set of beehive springs (like PAC,or comp) hardened pushrods (you would need to measure for correct length), and probably around a 228/230 duration (for a bigger cam) or if you want stockish with more power across the board maybe something like a 224/224 with just under .600" lift (spring life is greatly increased if you stay under .600" lift), then a 112-114 lsa.
Like you said, your working on a 5.3, not a 408, remember more cubes really eat up extra cam duration.

I have 220 k on the 5.3 in my truck and its never had any issues.
I'd like the same no hassle use from the car. But with more power.
