352/360 dyno results

Not as good as I had hoped

With just the hp increase that the carb gives, it makes you wonder what the 390 manifold would have done.

is that a stock waterpump , looks like a long pulley shaft . I like the looks of the engine . what rpm are the shortie manifolds good for before headers would be better ?

[Royce]

Yes  stock water pump for a 60 FE...Just guessing but I would suspect headers would start to eclipse the manifolds at about 4000 rpm

thanks , was wondering about maybe running the short manifolds instead of headers on a street truck , 1949 f 1 with 1966 t- bird 390 engine
