Re: IML: 1967 440 and trans {big valve heads}

["Frederick Joslin" <fljoslin@xxxxxxxx>]

Hi Bob:

I could be wrong on this, but I think that only the HP 440 (TNT etc.) had the 915 heads while the "normal" 440s and 383s had the carry over 516 heads from 1966 and before.

The 915 heads have the large exhaust valves that all post 1967 heads had (1.72" vs. 1.60") but still had the small comustion chamber from the 516 heads.

You can get almost the same effect by putting hardened seats for 1.72" valves into a set of 516 heads with a little bit of porting, but get the benefit of the hardened valve seats.    

Not trying to rain on your parade.

 

Still, a 440 is a 440.
