    I just bought a nice '68 350 with a stock 2bbl. I just found a stock 4bbl manifold from a '71 350 and I need a carb. Stock doesn't matter - drivability does. Prefer electric choke, but I'll defer to the vast knowledge of you guys out there.

    Go with a Q jet and electric choke from Ken at everyday performance or mark Northcutt they both do great carbs for these engines.

    Thanks Sean.
    The Quadrajet can perform great on your 350. And there are some electric choke options.

    I've been the route of carburetors other than the Q-Jet on other vehicles besides my Buick. Just go with a Q-Jet as has been mentioned. GM engineers spent many sleepless nights making them work properly. I've used aftermarket carburetors in the past, but I have to tell you that my Q-Jet experience is pretty good. There is the Holley/Edelbrock crowd, but there, you have a drag racing situation, and sometimes even then the Q-Jet will take you to the win.

    Don't rule out a Holley spreadbore 650!
    I have seen these make 400 hp on a 455 at a lowly 4400 rpm with better fuel usage numbers than a Q jet.
    Don't get me wrong, I love the Q jet , but sometimes these Carbs turn up for 25 bucks and all they need is going thru and a swap to a electric Choke!

    I recommend a Buick qjet with my electric choke conversion.

    It looks original, looks Buick, fits the best, and in my opinion will perform the best.

    So, I'm basically have the same question. I know I chatted with Mark a few years ago about going from 2bbl to 4 bbl. biggest soul search I had was whether to keep the ST300 or got o a TH350. Which has opened up a whole can of worms of gearing! If I can get the tail shaft sealed up on my ST I think it'll be time to pull the trigger on a 4bbl with the ST300. I'm curious if I'll face any issue for the kickdown connections?
