I have a stock 65 292 and would like to know if these little 'Pinto' carbs flow enough for my engine...I can deal with the jetting ok. This is in a C10 with HEI and 700R4. I dont expect to carry much weight, just looking for gas mileage.. any suggestions appreciated.

According to Tom Langdon, Holley Webers out of the box are good for about 200 cfm. My experience so far with two of them on a 320 cid GMC appears to confirm that. At 4,000 rpm your 292 will need 338 cfm. Two of them should work well for you; one is not enough, unless you are proceeding slowly by design.

God's Peace to you.

Tom, I have installed one of these carbs on my '65 Pickup with a stock 292 also. It has HEI, headers and an aluminum intake. I am not driving the truck as of yet (still finishing up body work) but I can tell you that after I installed it, it fired right up and idles and accelerates with no problem when it is sitting there. I was very impressed with the first fireup but I am afraid I can't give you any driveability performance on it yet.

Tom - the Holley/Weber 5200 is just slightly larger than the stock carb for your 292. You may want to play with jetting a bit after you get your truck on the road. It's cheap and easy. Go to the Weber Direct web site, and you'll find whatever you need.

Tom,

My experiance says it should work just fine. You'll need a one barrel-to-two barrel adapter that Tom Langdon sells for a simple bolt on experiance.
You should pull the jets out to see if they are the right size and in the correct position. Sometimes in the rebuilding process, they get switched. The small jet naturally goes in the primary. I use 51's in the primary and 54's in the secondary.
I have 3-HW on my warmed over 292. They run a bit rich but it purrs like a kitten when you open them up! Heck, I didn't spend all of this money to save on gas. Be sure to go with an HEI or Pertronics upgrade. They help quite a lot on starting. They look way cool too!

Thanks to all for the replies.I'm in the middle of a rejuvinate on my truck and have been collecting pieces for about 18 months.Since I'm going to have to come up with a linkage for the trans, I only want do do this once.For an adapter you would recommend???

If you are putting a 700R4 on your 292 you won't need an adaptor Tom. It will bolt right up. Now the trans mount is a different story. Try and find an automatic crossmember from a 63-66 truck and you should be able to adapt that to the 700R4.

GM Dad, thanks again for the reply. I'm all set with the trans. except for the tv cable set-up. I was able flip the e-brake crossmember and gusset it off the top frame rail. The e-brake is also set up using 99% original parts. I would really like to keep the truck as original looking as reasonably possible, but I need fuel mileage too for regular trips to Calgary (75 mi.one way)I didnt realise how simple it is to swap steering columns. I swapped my original shaft into a 76 van auto assembly and used my original wheel.Looks original enough to me.Anyhow,sorry for rambling,getting excited over whats finally starting to happen in the shop. Tom.
