How much horsepower does a 351 Cobra Jet engine have?

How much compression should a Ford 400 have?
Assuming your engine is the stock 1972 Model ‘S’ Code 400 engine and is unmodified by any previous owner the factory compression ratio of that engine is 8.4:1.
Whats the difference between a 351M and a 400?
To compensate for the shorter stroke the pistons for the 351M have a taller compression height so that it could use the same connecting rods as the 400. The result of the 351M using the longer 400 connecting rod was a higher connecting rod-to-stroke ratio of 1.88:1 than the 351C and 400’s of 1.65:1.
