post #40 lists a 650cfm TQ which never existed. but let's say for the sake of confusion that it was meant as Q-jet. there again, 404 no such carb found.
it also lists the E58 as 8:1 which, while true, isn't the whole story. some were 8.4:1 depending on year and motor code.
i'll buy that an EH1 had a 340 auto cam. i''ll also buy that an E58 had one as well (i had a dippy with an E58). i've put 340 cams into 360 2bbl motors and they ran like that.
