I dont know much about strokers and was wondering if you guys could help me out. I have a 1963 Impala with the old 283 in her and I was wondering if it is possible to build a 302 stroker from the 283 block? This may be a stupid question but I have not heard of it being done and wanted to try something different.

Thanks

 

Don't remember the exact way it goes but yes it is feasable. Either take a small journal 327 crank and put it in a 283 block or small journal 283 crank and use it in the 327 block then get the block bored for 302 pistons. One of those combos give you a 302 and the other I think was a 307. There's a book called "how to hot rod a small block chevy" that has the specifics.

 

The 283 is a small bore, with the 3.27 crank if I remember right it is a 302 point someting.

the 3.27 with the 283 crank is actually a little smaller , like 301 point something.

When chevy made the 302s for the Zs they used the 4 inch bore.

 

like the other guys said its doable. but i have to say its not going to be the best performer. the small bore motors really have a hard time running a decent sized valve, and the other end of it is that the small bore hurts headflow. given the size of the car its going in i'd say you'll be ahead with a 350 in there. just my .02

 

Yeah I wasnt really sure if it would be the best of performers. But I dont think this is going to be a "racing" car, just more of a cruiser or show car so the performance isnt that big of a deal, if that makes sense. I just wanted to do something different and thought that it might be something I would want to look into if it was possible. Thanks for the input and information, its greatly appreciated.

 

The 283 is 3.875" x 3.00". I think you can build a 307 with from a 283 pretty easily: 307 = 3.875" x 3.25"

Those old 283's revver pretty well.

I remember some guys, with a few tricks including gas ports and connecting rod bolts smaller than header bolts took the block to it's structural limits of about 14,000rpm.

I'm told that the cylinders walls collapsed inward.

Anyway, I think if I were you I might think about boring it, using the lightest components I could find and a dual-quad with Holley 390's.
Hooker super-comps, a stick shift, preferably a 5 speed or better so you can run 4.56 or 4.88 gears, and side pipes.

It's been done, but it's been a long time.


Uhhh...
BTW, is this really advanced?

Took me a minute to figure that one out
