My setup was a 08c6a6 with stock ls3,headers,ecs1500kit,methkit. I recently blew a hole through my block so I'm on the prowl for a new motor. Every used ls3 I come across ranges from 35~4k. I just stumbled upon a studded 402 stroker long block for 3500. Now I want to keep my my ecs kit, so would it be better to through the 402 in or wait to find a decent ls3? I'm not interested in spending 6k building forging a ls3. So what's you guys input... Pros and cons?
Not rocket science. A "properly built" forged engine will be better for boost than a stock one every time. You already blew up a stock one so that should be a clue.

yes but my real question is the the is the 402 stroker better for boost overall than the stock ls3
It's better, not because it's stroked, but because it's built.
If both were built with good parts some would argue the stock cubes is better. I would disagree, which is why I run a 402 myself.
Again. Comparing a built 402 to a stock LS3, I can't imagine anyone would suggest stock is better.
And 402 doesnt give near enough information to give any sort of recommendation. Built with crap parts by a crap builder? All we know is cubes, which doesn't tell us much of anything.
