How many ponies out of a bone stock 350?
 

How many horses did a factory 4barrel 350 put out in 1972??

175hp.

mine in the book claimed 220 from Factory 350 4b

In my '69 manual, it says 255 hp...that has to be at the flywheel, and even then I dunno if I believe it. BUT, now I have a rip-roaring 165 hp at the flywheel :rolleyes: due to a swap to a circa '73 350 out of a bus :rolleyes: :( .

ttt

My guess would be 260???

In the Chevy Truck ID Numbers 1946-1972 book has all 4bbl 350 cu engines listed at 175 hp for all. It also lists 2bbl 350 cu at 165 hp. :D :bowtie: :D

For '70 and '71, the 4 bbl 350 truck motor was rated at 255 gross hp. For the '72 model year, GM changed their hp ratings from gross to net , and the same motor was rated at 175 net hp.
