Is the stock Model A engine about 40hp? or am I wrong.. ??

This is from Bill Stipe's dyno results:


The A-6010-HC 5.5:1 High Compression Head made 38.16 HP @ 1400 RPM and 143.15 ft lbs of torque and 54.6 HP @ 2500 RPM and 114.7 ft lbs. of torque with the A carburetor.



however... Tom from Snyders told me I should only expect about a 5hp gain.. ?

I do have the Aries 'A Muffler' which should flow a bit better than stock.

Thanks!!
How can I view the Stipe dyno results? Thanks.
