"or something..."
360 horse at 4600 rpm, 480 tq at 3400, or so it says here:
Great Old Cars: Ford Engine Statistics
These were "gross" hp numbers, and you can figure about 80% for net. Some were underrated, and many 429s fall into the underrated catagory.
These also had pretty high compression, 11 or 11.3 for some. This is the "basic" "Thunderjet" engine as found in Tbirds and other pillow barges. CJ and SCJ and Boss engines are rated higher.

I just picked it up from a guy. It runs or ran when it was parked. It is an an original engine i had just planned on rebuilding it and putting a better cam in it and changing the intake and carb. Maybe i'll have to use a slightly thicker head gasket or something

Ford claimed 11.1 to 1 compression ratio for the standard 429, while the CJ was rated 11.3 to 1 with a nominal number of 10.7 to 1, whatever that means. The Boss was rated at 10.5 to 1 compression.
My reference is Ford's Muscle Parts Book, Supplement NO. 1 dated July 1970.

Thanks for the update, that link I posted is pretty weak. Couldn't find anything better in the 45 seconds I devoted to the search....
