Blown Stroker
Hi I'm looking to build a blown 383 Stroker, and the rotating assemble I purchased is part #SCA-1-90355BE
http://store.summitracing.com/partde...E&autoview=sku
I am planning on using Weind 177 Pro Street Supercharger, but have to watch the amount of boost since the crank isn't forged. What do you guys think and any suggestions on a supercharger or parts to use? I couldn't get a rotating assembly with a forged crank due to them being too expensive and also because I am a college student, I have to save my money in order to get it done. The pistons and the rods are forged. Right now I'm just looking to listen for suggestions. With 70cc heads the compression would be 9:2, and I figure maybe with some 75 or 76cc heads I would get a compression ratio of around 8:1. I talked to a person from SCAT and told me that the crank is rated at 600hp @ 7200RPM. What do you guys think?

Focus on school-future; six months after graduation your tastes or your realities (or both) will differ much from today.
For now, use parts you have on hand & fix only what you must ... build a mild, reliable, normally aspirated 383. 76cc iron heads, -18cc dish & fp1094 gasket makes at least 8.5:1 scr 383.
But, if your present motor is running OK then leave it & return or sell kit. Good luck in your endeavors.

You're going about this all half a$$ed. You bought a rotating assembly that is of questionable strength in a blower application and I'm guessing that you don't have a lot of experience with artificially aspirated engines. Regardless of what the blower manufacturers say, these things are not a bolt on and drive away item.

I'm not planning on running lots of boost. The engine in my corvette is in really good conditions, it only has 71,XXX miles on it, the car wasn't driven in bout 15 years. If I don't add a blower, I might just go naturally aspirated and try to make as much power as possible.

I really want to have a blown stroker, I did a lot of research and contacted someone over at SCAT to give me a little bit of more info on the rotating assembly and the told me that the rods can handle up to 750hp and the crank 600hp@7200RPM, which is good enough. Do you have a blown 383 or a 350? How much power is it putting out? If I do the blown stroker I'm not going to drive it every day, only in the weekends, I have a 78 Z28 Camaro that's the daily driver for going to school.
