Someone correct me, but I'm pretty sure that the flat top pistons from the '76
1500 engine are what make the difference.  Vicki Brit lists the '76 pistons as
'flat top' with a 9:1 ratio.  The '73-'75 and '77-'80 1500 pistons are dished
with a 7.5:1 ratio.

Now can anyone out there tell me.  Can the '76 flat top pistons be put into a
'79 1500 engine?  I have a spare engine that I plan on rebuilding for my '77
and I don't intend to build it stock.

Thanks,

My understanding is the high comp. comes from a longer stoke.
Bore size on a 1296 is 2.90"
Bore size on a 1493 is 2.90"

You might change the heads and not get anything.

Hello,

Would a head from a '65 1500 engine fit my '72 1300 engine?
The engine is the later-type 1300, which uses the 1500-style
head gasket.

The '76 cars were supposed to have 9:1 compression, and
(possibly with a bit of milling), I could have a high-compression
head for my car without messing up the original one...
