well for me there is a multitude of reasons and I'm going turbo charged, more efficient hp than super or blown and when it comes to forced vs. HIGH C.R. N/A. There is very small price difference in the over all build either way I'm spending good amount of money on Ignition and Fuel system so why not. I'm not looking to break records or be the biggest guy out there or anything, I just want to have fun and doing this kind of build is a part of it for me. If i wanted to go fast for cheap I would just do what everyone does and get a 454 and slap boost or nos to it till i blows up and get another one! Plus its for my 69 Nova so I'm looking for handling, power, and engine response.

283 Crank id issues!

I checked out the casting number on 8 different websites. Seven out of eight say it is a 283 small journal forged crank. The only site to say it was cast is nastyz28.com. I have found information from that website to be incorrect several times before.

I will build another 283 when I find the correct car to put it in. I think a 370 horse N.A. 283 would be fun. for a turbo small block,I think the 6 liter ls engine is the best place to start for being practical

I totally agree that there are more suitable and practical ways to go. However the reason for this build is for nostalgia with a modern twist but is mostly for a family member that has recently been diagnosed with cancer and is my inspiration for the engine. He had the 302 Camaro in his youth and it later became his speed boat engine after totaling his Camaro. When he put it in his boat he painted the engine pink and once I have mine together I will also follow suit and pay homage to this man who has helped shape my life. Most likely more than most of you wanted to know but that's my reasoning behind this build.

As far as the crank goes I think it is a cast steel I recently bought a forged steel crank and have them side by side and you can see the difference and even hear the difference when you tap the counter weight with a hammer. I'll try to post some pics up once I get the photos up online.

You are welcome, Rick. You may be surprised to hear how many guys ask about building a clone of the 'mighty Z28 302'- there's at least one a month here alone. Times that by all the sites and all the other people who never post about it and that extrapolates out to a surprisingly large number of people who might build one if the pistons were priced like a 283 piston (which it essentially is). This makes me wonder why one of the companies doesn't tool up for a run of them.

In your case (using boost), you'd want forged. But for the majority of builds, a good cast piston would be just fine.

FWIW, there is a franken-build you could do using the crank and rods from the Gen 2 L99 engine. The rods from the L99 are 5.94", this will allow you to run off the shelf 350 pistons with the L99 3.00" stroke crank. Takes a 1-piece rear main seal block.

Or use spacer bearings to put the SJ 283 crank in a 4" bore block. Use the L99 rods to run stock CH 350 slugs.

BTW, the rear seal area of the 283 crank has to be inspected to see if it originally used a rope seal or 2-piece rear main seal.

I have a set of new reconditioned 5.94 rods and a set of std. flat top forged pistons on E-bay right now for a really good price.

I ended up buying a set of I-con forged hollow dome pistons ($400) and forged lightweight rods for mine. I did this because I got a deal on some aluminum heads with 64cc combustion chambers. I sold the LT1 heads I had.

And yes, there are forged and cast 283 cranks. I have both. The cast has the same casting as one one posted above.
