Installing a Tunnel Wedge.. and

[Bobcat]

Undy ... have you looked at the Holley 1850 List carbs ? They are supposed to be the aftermarket equivalent of the ones you are looking for . I`m running two of them on my 427 S/0 in my Galaxie as I was too cheap to pay the price for the originals . Mine are vacuum secondaries and highly modified by Competition Fuel in Tucson ... flow about 660 cfm each according to Competition`s flow bench .

Yea, I've looked at the 1850s but was warned by quite a few about tuning nightmares as they (and others) come factory set up to act as one carb. If I had a specialty carb shop that I could trust to set me up with a set of matched and adjusted carbs I'd go that route. If I can't get a lead on a couple BC/BDs I'll do research in that direction.

Dave ... Not that I doubt what you said , but I haven`t had any more than the "normal" problems ( PV rupture etc ) and my carbs were bought separately . Yes , I did have them blueprinted .... and I be glad to tell you what jets are in all circuits if you decide to go that way , but I haven`t had any real problems . The biggest "problem" I had was tuning the vacuum secondary opening with a heavy car . Used Holley`s quick change vacuum secondary kit to dial them in .
Either way ... good luck ... that ought be be a blast with a tunnel wedge MR intake on the engine .

the repops as i understand (which may be wrong) are avail thru certain suppliers only. i have a set on mine. mine were purchased thru carl's ford parts
he has a web site, with that being said the carbs i got were crappy at best,
they were new but required total disassembly and casting flashing removed from
just about every surface. nothing was nice except the fuel bowls. even had flashing covering some metering plate holes over 25%. i have at least 20 hours
into making them right. oh and they still leak. is it that i am just lucky or are they all like this? i can't say for sure but be forwarned. if i was making the decision now, i would go with the new carbs suggested in the previous thread. the 1850's
you can use any vacuum carb as long as it doesn't have secondary metering blocks, you must use the zinc type jetting plates for the secondary circuit because of clearance between the carbs.

as far as the tuning no matter what you buy you will have to jet them according to your setup, the factory jetting will be too lean if you as much as put in a cam other than factory lift and duration.

buy smart the factory repops don't offer anything except the ford numbers stamped on the airhorn.
