That head was used on 71-72 350 LT1 engines. chambers are 75CC.
THE BLOCK CASTING NUMBER IS BEHIND THE CYL. HEAD. SORRY CAN'T REMEMBER WHICH HEAD. IT USUALLY IS A RAISED SEVEN DIGIT NUMBER. THE CYL. HEAD CASTING NUMBER REQUIRES REMOVING THE VALVE COVER AND CHECKING THE RAISED CASTING NUMBER ON TOP OF THE HEAD. YOU CAN CALL A DEALER OR A ENGINE REBUILDING SHOP AND GIVE THEM THE NUMBERS. THEY SHOULD BE ABLE TO GIVE YOU THE YEARS THAT CORRESPON TO THE CASTING NUMBERS.

I don't believe 378999 is a valid casting number for a block or head, however, check the website,www.mortec.com, for SBC casting number information. For Chevy cylinder head specs, try this one: http://www.73-87.com/chevy_ids/sbheads.htm And, another good site for block suffix codes, block casting numbers, and cylinder head specs: http://www.chevy-camaro.com/chevy-camaro-engine-codes.asp Thanks, dave
