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
where can i find my casting number on cylinder head for 1993 Honda civic

The casting number is 0331
Under the valve cover where the valve springs are.
A small or big block Chevy have a casting number on the top of the block behind the driver side head. MorTec has Chevy casting numbers listed online.
write down the casting number under the valve cover and compare it to the list of chevy head castings at mortec.com
What is testing number for 1987 Ford Ranger 2.3 L
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.
for a 2.4 liter dohc quad 4 the casting number is 24574683-18
If it has a 5.3 engine, first have the cylinder heads pressure tested. Heads with a casting # of 706 like to crack in the number 1 head bolt hole. If this happens, replace head.
Serial number, and or engine or vehicle code are stamped on the cylinder deck on the right front of the block immediately in front of the right cylinder head. Casting numbers and date codes are on the right rear of the block just in front of the bell housing mounting surface.
