eddy 650 or 750

holley 750 double pumper

i was actually thinking about a dp but id rather not

go with the 750 ,you wont need to replace it again when you add the better heads ,also were you looking at one with a avs its never to big .
i was looking at both the performer and avs but i couldnt figure out the diffrence between them. other then a performer is a afb and a avs is well an avs with a electric choke
