"the 283 was a small journal,the 327 was made both in the small and large journal. By using the small journal 327 internals in the 283, you now have a stroked 302, excellent for high rpm at extended periods of time."
.
With respect, I have to say the above statement is incorrect...
A 283 bore(3.875") with a 327 stroke (3.25") yields a 307.
A 327 bore (4.00") with a 283 stroke (3.00") yeilds a 302. (or 301 as the hotrodders called them before Chevy brought out the 302)

I was just saying bore out the 283 to 4 inches b/c I read in my 283 Hi Po book that the later block 63-67 will bore out to 4 inches when the early ones 57-62 will only bore safely out .060 due to already being bored from the earlier 265 blocks.

I was just wondering why you said "there's no replacement for displacement" in one sentence then talk about your 283 "stroked" to a 302 beating larger displacement engines in the next paragraph. 43 years of engine building experience leads me to believe that sanctioning bodies limit engine displacement for a reason.

A 283 with a 327 crank is a 307. If you clean up the bore to 3.905, it's a 311. We use the 307 cranks to make 327's for road racing in early 60's Novas.
