 Post subject: Carb needed, '81 D150

Car Model*: 1981 D150
I just bought a nice 1981 D150, shot bed/single cab. Body's in great shape, no rust on the body, bed, or frame.
Wiring in the cab and engine compartment is hacked, but easy enough to fix.
Compression is not great, 125 highest to 100 lowest.
It still has the lean-burn and distributor, but the carb is missing.

I've read up on the info and advice here about removing the lean-burn, and I believe I have a good handle on the dizzy that I need (single pickup, vac advance, convert to HEI), but I need some help and the carb.
I've read here posts referencing the Holley 1920 and 1945, and also some others.
But I haven't seen any info re: which carb is appropriate for a given application.
This truck has the auto trans, no AC

My intention for this truck is the occasional week-end local driver, going to car shows, et al. Eventually will either rebuild this engine or go the resto-mod route with a 5.7 Hemi and drive train from a newer Ram 1500.

Please advise on the carb.

thanks,
Rattlecan

Also, I have a good handle on fuel and vac lines, and throttle linkage.

I'm less clear on the transmission linkage to the carb.
I believe it cams downwards, but not sure of the linkage connection and how far it is supposed to travel at partial throttle and full throttle for passing gear.

Can someone please post a pic or two of the trans linkage attached to the carb?

Thanks again,
Rattlecan

I believe that if you get the kick down linkage too far out of adjustment performance and your tranny will suffer.
Post in the parts wanted, you should be able to get a 1 bbl and a kick down linkage,,,,

there are sites that have Factory Service Manuals on line, I don't frequent them as I got a FSM for my '83 D150 off ebay some time ago.
I'll search around and post back.

That is a fine looking D 150, looks real solid,
another thought for a carb,, look around on e bay, or there is a carb shop that I delt with some time ago, Daytona Carbs I think is the name, They had a lot of kits for older carbs,
they may have a line on a complete kit,,

Rattlecan, that is a good looking truck.

Not to hijack this thread, but what about the Autolite 2100? Adapters are available. Is it difficult to adapt the linkage onr a D150 with the 904 automatic ? Many seem to like the 2100. Actually, some even think the Chinese copies of the 2100 are better than the same for the BBD.

I'm converting my '84 D150 to a two barrel. If its worth the effort I'll change to the 2100. Tonight I picked up a cheap BBD from a Facebook Marketplace listing, but wonder about the 2100. Dadtruck, do you know anything about the Daytona "universal" carbs from that link?

+1 for the 2100. Easy to rebuild.

I have no experience with the universal carbs from Daytona Parts.
But I have bought carb rebuild kits from Daytona and the kits were
of good quality.
I could imagine that rebuilable carburetor cores are getting harder to
get. So it is a logical progression that new - old style carbs would become
available. Daytona Parts must think they are good as they put thier company
name on them.

Exactly. I've rebuilt dozens over the years and even sent one out to get the throttle bore rebushed. They are a good upgrade over the BBD because they actually work off road.
