Question about my 74 vette

I'm having problems finding out the combustion chamber size on my 74 corvette. I've got the stock 5.7 350 if anyone could help i'd really appreciate it. Thanks!

Mortec.com has a pretty thorough listing of casting numbers and CC's.Your heads are likely 76 CC.

You probably have the 76cc chambers. If you have the head casting numbers, I can tell you.

I'm not sure if the L-82 had smaller chambers.

Vetteguy1974: do you know if you have the L-82? If not, look at your VIN number. The engine code for the L-48 is L, I think the engine code for the L-82 is X. It should be about the 8th digit.

i didn't see a L or an X in the vin number at all. i know that i've got the least powerful v-8 i want to say it's 195 HP and i'm not sure what engine it is.
