Edelbrock actually used to make Q-jets, but stopped a while ago.. -Otherwise -if you want a new carb you could go for a new q-jet from summit or jegs ??

Btw, i have a Edelbrock 800 cfm AVS (for 434 cui) , and it is an easy carb to 'work' on, but th Q-jet's are awesome when dialed in, both in economy and performance..

I would recommend a vacuum-secondary carb, in any case.. (the avs/eps Edelbrocks are mechanical BTW)...
