Thread: Stroked 283?

Tweet

I have a 283 that has been rebuilt and bored .020" over. I read a 283 bored030 over with a 400 crank would make a 360. what other parts do I need to do this?

where did you read that? 283 is a small journal and a 400 is a large journal, trying to fit a large journal crank in a small journal block is kind of an odd idea, don't think even turning the journals will work for that.

what crank should I use then

ither a 283 crank or I guess you could use a small journal 327 crank.

could I use 283 con rods w/ a 327 crank

Isn't a 307 a 283 with a 327 crank? You've got all of the parts you need right there.

Actually, the displacement would be 357.5 cubic inches. The 283 has 2.30" diameter mains and the 400 crank has 2.65" diameter mains, so the crank would have to be machined. Then you'd have to find custom pistons with the correct pin location to get the deck height correct. In short, this isn't an "off the shelf" build. None of this would be as cheap or as reliable as building a 350 and you'd end up with about the same displacement. Why bother?
