I'm looking for a chart of the 350-4 horsepower and tork at x-level of RPM. Can't seem to find it on the web though.
Here is one..... This is input with headers and open exhaust, as that is how I think Buick rated the 350 in 1970...with no manifolds. Thats what "Pop" always told me anyways.... he worked at Berkley Buick in Minnesota back in the 60's.
Aaaaaaand......... if you throw a TA212 cam and DP intake in the same engine...... this is what you should get.
