any info on these would be great,was told 1 is 850 h.o.[8026B on base],used that on my 440,the other 2 are 4780,4778,,thanks

The 4780 is an 800dp, the 4778 is a 700dp, the 8026B is not a good # (probably the base #), I'll assume this is the one in the bottom pic that has the choke tower milled off, it does look like an 850 from the size of the venturies though. Hope this helps.
