Good morning all.
Tech question for a 63 to 68 Corvette SS/I-HA combo .
I was recently questioned about piston in a 327/300.
The classification guide states flat top with notches on the 63,64,65.66 & 67, 327 Corvette engine..
On the 68 327 it only states flat top. To my knowledge all the 327/300 had notches, regardless of the year.
So my question is are the flat top pistons with notches legal in my 68 Corvette SS/HA?
Thanks in advance.
