How much horsepower 350 has

Question

how much horsepower does a 1987 350 motor and 1978 rochester qudrajet 4bbl carb has

Answer 1

200-210, if it had any other kind of work done to it, probably more, headers=10, cam=5-50, milled heads=20-50, porting=0-50 a combination there of is worth another 100-200

Answer 2

There are a wide range of answers to this question.

GM made heavy duty truck versions of the 350 cubic inch motor with "4 bolt mains" a low as 190 horsepower for 3/4 ton and 1 ton pickup trucks, say in 1978, 1979.

On the other hand a good rule of thumb for hot rod motors is one horsepower for every cubic inch with high performance headers, mid or high rise intake manifold, an agressive cam, and high compression between 9.5 and 10.5.....

Recent electronic fuel injection motors make more than one horse for every cubic inch, approaching 100 horses for every liter ( 60 inches ) displacement.

The biggest problem for Four Barrel V8's is that the larger fuel droplets travel to cylinders 1,4,5, and 8 more than the inner cylinders 2,3,6,7 so the outer cylinders are rich while the inner cylinders are lean. This is really bad because lean is hotter, and the inner cylinders don't shed heat as well......
