I checked out the web sites that John so thoughtfully provided:
Ford 300 Chevy 292
hp 150@3400rpm 153@3600rpm
torque 260@2000rpm 255@2000rpm
bore&stroke 4.00x3.98 3.85x4.125
compression 8.8:1 8.0:1
The Ford 300 numbers were for their 1994-96 EFI model. The nethp and torque for 1965-72 was 170@3800rpm & 283Lbs/ft@1600rpm; 1973-74 101hp@3000rpm & 223Lbs.@1600; 1978-86 120hp@3400rpm & 223Lb@1600rpm; 1978-86 101, 115, 117, 120hp@3000-3400rpm & 223Lbs. torque @1600; 1987-93(EFI) 145hp@3400 & 265Lbs.@2000. So you can see the numbers for the Ford vary quite a bit depending on the year whereas Chevy only listed one set of numbers at their web site. However, the numbers for the later models are quite competative with each other and I have to make my decision based on the other factors (availability of parts etc.) and what I usually go with - which shows up first at the best price.
