Different HorsePower ratings
I have a 350 4 barrel 4 speed 70 GMC 4x4 what would the horsepower rating be? Were there only 2 different rated HP 350's or more. Cannot see the block number and the heads have what looks kind of like a tall skyscraper off to the outside edge.
Thanks for any help and Merry Christmas to all. Ron

Re: Different HorsePower ratings
My 70 Chevelle has a 350 4b. rated at 300hp. I think the 2b was rated about 275hp. I might be wrong but I do know my 350 4b was rated at 300hp.

Re: Different HorsePower ratings
You could only get one 350 on light duty trucks,the 4 Brl. In 1969 and 1970 it was rated at 255 GROSS HP (200 net HP).
If it isn't the stock motor it could be anything. What are the numbers on the passenger side head front?
