If your planning a small block build and planning to go with a forged crank, it really doesn't cost that much more to stroke it out to a 3.75'' stroke and end up with a 383. In my opinion well worth the extra money and labor.

I've actually have considered a 383, but don't really know much about that kind of build.

383 is a 350 bored 30 over with a 3.75 stroke yeah just tell the shop u want it machine to be made into a 383 and they will get ya going its the same as building any other engine just different parts and go with a 6.0 rod it reduces outward pressure on the cylinder wall making it more efficient

Default s10

Laxking,
You can run 12.25's with a 350 at .060 over, stock stroke in a 3000# S10, powerglide, 4.56 rears, that's what mine runs in cool weather. Most of the time I run 1/8mile at 7.75's at 88-90mph. And it has the stock s10 rear end with traction bars. I race at 350' above sea level, that helps a lot. It wouldn't surprise me if my rear end fell out on the next run, but I've been running this same combo for about 4 years with no problem. It also has mid 70's smog motor heads, but it has a good cam, intake, and all the other parts. I went with smog motor heads because they are cheap, and I had them, and comp ratio worked out to be 10-1 so I could use pump gas 93 octane. Hope this helps you some. dgh

Thanks everyone for the replies, giving me a few things to think about doing. As far as going 383, I've seen Summit has bottem end packages from Scat and Eagle, are these a good way to go, or what should I be looking for as for parts to build the 383?

the rotating assembly are a good start or you can do it like this

FORGED 3.750 stroke crank for a 350 a good block bored .30 over and notched for clearance, forged 6.0 rod, some high dome pistons, aluminum heads (everyone i talk to THAT RUNS PROCOMP says procopm is good for the money) and a good cam to fit the build. thats how i would do it
JMO id go with forged crank and rods if you can afford them just for extra insurance but the scat 9000 crank is a good cast crank from what i hear

watch what company crank you buy very close. scat is a import blank crank.meaning they import the blanks and turn them. meaning softer steel or iron.
