SB chevy 350 build. Have some questions
Ok, I bought a chevy 350 four bolt main for 400 bucks and it is bone stock. It is a Vortec motor out of a 99 full size van. It was rebuilt when the sold it to me, but that shouldn't matter all too much as I have some plans for it. First off, I would like to get 350 to 400 hp out of it at least if not more. I am going to carb it and sell the intake that is on it. I want to stroke it and maby bore it too. I have seen stroker kits with forged parts on ebay that look like they should do the trick. I also want to run a turbo charger with 5-10 LBS of boost. I hear you need to knock the compression down to do so and run forged pistons and rods, correct? Also, what kind of gains would I get with the stroker kit? Any suggestions on a cam? I hear that you should go with a mild lift cam if you put a blower of any kind, correct? Also, do you think a 350's rod bearings will hold up to that kind of boost? Any constructive cridisiem is welcome. BTW, I am looking for low end from the powerplant and top end from the turbo. All thoughts are appriciated and thanks.

What is your inteneded purpose?
Vance,
okay so let me get this straight.........you want to maybe bore maybe stroke and also disrupt the relationship to atmosperic pressure on your small block? There seem to be a lot of maybes and a shortage of info.
What is the motor to be used for? What vehicle, trans, rear end and ratio? There are a lot of variables and measurements that you NEED to understand before buying parts.
That being said....you did fine on the four bolt block. It is my opinion to buy all of my internal parts new from a local distributor, ebay scares me but it is up to you. Once you finally decide on the rotating assembly you need to mock it up. Check things like the piston to deck measurement for your squish area and also if you are out of square. CC your heads and have the valve job done. Work the math and get direct measurements..........
This is just the tip of the iceburg and you can never get enough knowledge but you can gain understanding if you slow down and learn how to do this right. Beware the magazine sales stories and the drunks at the bar, if you really want to know check out the guys who are running at the track. Ask a lot of questions and don't buy anything until you know exactly what it is you are trying to do and why!
