Are 283 pistons same as 307?

Are 283 pistons same as 307? They are listed as same bore but do the have the same height?

 

Nope. Different stroke but same rod length.

 

The pin to piston top is different between a 283 and a 307. A 307 has a shorter pin to top height. If you put a 283 piston on a STD chevy 5.7" rod on a 307 crank, the piston will push out of the top of the cylinder

 

Both stock bores are 3.875 but I was also told that the pin to deck height differs. The 283 stroke is 3" whereas the 307 has a 3.25" (same as a 327...) I have a '68 307 sitting under the work bench at home that I wondered at one time about having sonic checked and bored to 4" but decided it wasn't worth the effort.

 

the differance is called compression height

 

with custom small journal 5.95" rods, you could I guess.

 

you mean 5.825 in rod

 

My book shows;
283 = 1.805 CH
307 = 1.675 CH

I hope this helps.
