Ineed calculate compression ratio to this 292-y and what Blower drive ratio is good to standart 292:-y
Block identification number generally on side of block above oil filter for blocks cast at Cleveland. Dearborn block I.D. number near distributor and above generator. Most Dearborn blocks used in trucks. No Dearborn blocks after 1957. There were no special truck blocks. Heavy duty trucks with steel cranks used C1AE or C2AE car blocks. Nearly all Dearborn blocks after 1954 were 272's. Most 292 and 312 blocks are from the Cleveland foundry
and mine is "c2ae" and motor is old fire truck motor Ford F600
Heavy duty trucks with steel cranks used C1AE or C2AE car blocks.

and head is this "c1ae" and original carpuretor is 4bbl this is weird combination to HD truck?
YEAR 61-62 CASTING # C1AE Cu.In.292 Int. valve 1.64" *C.R. 8.8 CC’s
72cc H.P.?
BLOCK CASTING NUMBER:
312's can have the following block casting numbers ECZ-6015A, ECZ-6015B, ECZ-6015C,EDB-6015E, B9AE-6015F. Of these ECZ-6015A and ECZ-6015C are by far the most common 312's and are likely to be a 312. Some 312 replacement blocks were C2AE-6015C
and What the F...this mean? =D number C2AE-6015C ^^^bossible 312

*Compression ratios listed are from Ford literature and are theoretic figures that exclude deck volume and head gasket displacement. Most published compression ratios are approximately 9% higher than actual.
When engines are rebuilt with composition head gaskets deduct about 12% for actual compression.
Do to the thinness of the deck surface of some Y-Block heads, particularly the ECZ-G heads, it is recommended that unposted heads not be milled more than .025". Posted heads have been milled up to .045" without trouble.
Heads with large "S" in between center exhaust valves are service replacement heads as date codes are after production run.
