need help asap what carb for my motor 600 750?? edelbrock

eddy is on just like i said i got a 750 with all the linkage from my buddy so i bought zero for a carb that was just runing 2 months ago ill start here and go from there
as far as what i was told is the holleys on a mopar take some fitting and changing of things
i dont know if thats tru or not because i see eddy on them all ever had a chance to really look.

yes power valve blows from back fires thats why i got sick of holly probley 5 to 7 years ago i would lose my tune and get back fires at the track leaving the line to about 60 foot and out went the PV

im not pissing in any ones cheerios about this every one has there own brand and likes
simple as that maybe a holley will go on next but for now ill take the free 750 and try it
