Re: Help with newly acquired 72 350 Auto


Don't think personally that the Edelbrock carb is the way forward - its their version of the Carter AFB which, arguably was one of the best performance carbs of its day - but now doesn't seem so good in its present form. You'll need to change the inlet manifold - so why not consider a higher spec' Holly (or generic equivalent) vac secondary - infinately and easily tuneable.

Re: Help with newly acquired 72 350 Auto


James, I'm not going to pretend to be an expert on carburettors, but I have had to do a bit or work on my Rochester and found that the Haynes Manual wasn't accurate enough for my '78. I bought this book:

https://www.amazon.com/Rochester-Carburetors-Revised-Doug-Ro...

Much more detailed with masses of info on set-up, etc. It may be worth getting a copy before going down the replacement car route. (You'll find that Doug Roe is a huge fan of Rochesters and reckons that, properly set up, they are the best option! Very Happy )

Re: Help with newly acquired 72 350 Auto


Be honest, just take the choke off, not really needed especially if you donít drive a lot in winter, just means you have to sit there and tickle the throttle for a couple of seconds, I find the early Qjet choke more problematic than good!

The other option is to knock the lock pin on the secondary flap shaft through a bit with a punch so the choke mechanism donít touch and lock it, itís only like a Clevis pin and only needs to be pushed over about 5mm.
