I feel like this question will have been asked many times already, but I haven't been able to find much in the search... so here goes

I want to convert my '67 326 2bbl to a 4bbl. I've been reading around here and other places, and a properly rebuilt and tuned Quadrajet seems like my best option - over a Holley or Edelbrock. So I'm wondering what issues I can expect to run into? Obviously I'll be needing to buy the carb and a new intake. Provided I buy a compatible year/model QJet, will the fuel line reach the inlet? How about the throttle? Also, the vacuum lines from the intake - will I need new ones, or will the ones off my 326 2bbl work?

I will be buying a core and rebuild kit from Cliff's, as I've read good things about them, don't think I'll find a core here in the UK. But I would like to know what year/model people would recommend... Electric/Manual choke - was thinking of manual, but maybe if the vacuum lines won't fit, an electric will be easier.

Intake... I heard from this board that the stock Pontiac intakes are among the best. I will be needing a new 4bbl intake, so for ease of purchase was going to go for a Edlebrock - I doubt I would really notice a difference? The pictures seem to show threaded holes where the PCV should connect to, does the intake come with adaptors?

Feel a bit bad asking so many questions here, hopefully I can start chiming in soon.

Thanks so much for any help!
