Rochester or Carter? 1967 G10 250cid
A good friend of mine needs a new carburetor for his '67 G10 van since we found that the Holley Economaster 1bbl had given up the ghost internally (accelerator plunger crumbling, metering rod fell out, vac leaks at the power valve, etc.) The local shops show a Rochester B or a Carter YF for the 250cid that year, anybody have an idea which would be better given that they both bolt up the same? The only option for a '68 would be the Rochester M and we could get that in a day from the warehouse.
About the van: He's had it 10 years, love's the thing. It's a primer black cargo van that has a 3" lift kit and huge tires with chrome bullet hub caps from a ?DeSoto. The guy who owned it for 20+ years before him modified everything, including the aftermarket carb, cruise control, guage panel, carpeting, sunroof, turboglide tranny, etc. We hope to rebuild the Holley and keep it on hand for a later swap if the rebuilt stock carb doesn't hold up. |

Re: Rochester or Carter? 1967 G10 250cid
Welcome to the board!
If you decide to go with something other than the carb you currently have, make sure all the fittings and whatnot will line up or at least be prepared to modify. Having said that, my C-10 originally came with a Rochester B carb and I hated it and all the replacements I had to buy. I've never tried a Carter carb, but it seems like I've heard they're good carbs. If you can rebuild the Holley or find a quality rebuilt replacement, that's what I'd do without knowing more about your situation.

I rebuilt my Rochester B, but have only 600 miles on it since then with no problems.

Re: Rochester or Carter? 1967 G10 250cid
I hear good things about these engines with smaller 2bbl carbs.....I believe there is a post here about using a motocraft 2bbl 350cfm carb, should be doable with just a 1bbl to 2bbl adaptor plate.
The 4bbl upgrade is always possible.....but I wouldn't recommend it if you plan on staying relatively stock (you can find many a headache threads about that...by me)

Re: Rochester or Carter? 1967 G10 250cid
Thanks for all the input!
He actually had a 4bbl intake and gave it to another friend awhile back. The guy tried it but must have had a big carb because he removed it after flooding problems. I'm just trying to help him get back on the road. I think I found a kit for the Holley on ebay but who knows how long it will take to get here. We're gonna try the Rochester M and if that doesn't work I told him he could drive my Nova (1970 4dr 250 Powerglide with a crunched front end and bullet hole in the trunk UncleT |
