*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.

 

5752-113 was sold as replacement head for ECZ-G

 

B9TE was replacement for 5750-471 B9AE was replacement for 5752-113

NOTES: ford-y-block.com

 

For 256 use 272 bores with 3.10" stroke.

 

3.10" stroke is "EBU" crankshaft from ’54 239 or ‘54-55 256 cubic inch engines.

 

3.30" stroke is "EC" crankshaft from ‘55-57 272 or ‘55-64 292 cubic inch engines or C1TE steel crank..

 

3.44" stroke is "ECZ" crankshaft from ‘56-60 312 cubic inch engine.

 

3.51" stroke is "ECZ" crankshaft offset ground to 2.100" rod journal for aftermarket

 

connecting rods. Assumes starting with .020" undersize journal.

 

3.53" is maximum offset with standard diameter rod journal.

 

3.64" stroke is accepted maximum stroke. Some rod/camshaft interference. Clearance rods as required.

 

Longer than 3.70" strokes require reduced base circle cams or 2.00" rod journals,

 

additional clearance grinding of connecting rods #1-3-5-7. Equalize weight of

 

#2-4-6-8.

 

Not shown. Standard 3.30" stroke cranks can be offset ground to 3.41 stroke.
