I don't know if they still can but when I worked at a CarQuest store years ago they could search inventory of EVERY store in the country. I found a lot of hard to find parts that way. If you can get to a willing counterperson at O'Reilly who will got to their help guys in Missouri they can find a lot that os not in the regular system. Many of the new counter folks haven't even been told of this service.
It cost more to turn a 250 into a 292 then it is to just build the 292. Plus, the added machine work to the block to have clearance for the rods / crank. Yes, the blocks are the same width, you would also still need to use a 292 cam because it has clearances in it for the rods.
^^^ I have access to two engines, a 66 and a 69. Any preference to the 6 vs 12 counterweight cranks when mating to a 700R4?
Some of the early 6 weight cranks were forged but moat prefer the fully weighted cranks. A good block is harder to find than a good crank. If one is a Mexican block take it.
I thought i would get everyone an update on the intakes.Steps 1,2 &3 are complete at this point just a few more to go and these guys will be called done.
@Six Ball , No such luck on the Mexican block. Of the 3 engines friends have, two are 1969-70 (12 counterweights), and one 1966 (6 counterweights). May get all 3 and use the block with the least core shift. That will also give me 3 sets of heads to work with. Mexican blocks a hard find here. @Twisted6 , those castings are looking good. Keep the pics coming...
Bangingoldtin Thank you. I have a USA 292 but it has a Mexican crank go figure that one. lol and this was a propane 292. (Is what it ran on).
You'll be fine. Pick the best of all the parts. Someone else will want the rest. Maybe make a buck or two for the project.
Well one more step out of the way. The final will be to cut the linkage towers down and drill and tap them. And I think they will also port out nicely.
OK guys, I did get the 69 motor (turned out to be a 70 with only 50K miles), and plan on getting the 67 motor for a spare head to play with. Started collecting parts already. One question has arisen though- with the new flexplate and spreader ring, along with the crank flange, what are you using for bolts? With all that, the bolt needs to be .8125" long for full threading into the flange. ARP 146-2801 (Jeep 4.0) is 1/2-20 and .875" long. Would that work?
Yours has 1/2" bolts? Not all of then do. I think most use small block bolts for the smaller size. I don't know if some V8s used 1/2" bolts 400 or big blocks? If so that is what I would try, but I doubt that 1/16" behind the hub would be a problem.
when my 292 was coming together for my 37 coupe, changing from a stick to auto, I had to get special flexplate bolts and could only find them at a chevy dealer. no clue as to part #
The 292 may be the lone ranger of Chevrolet engines that has 1/2 inch bolts rather than 7/16 bolts but believe me the have 1/2 inch bolts and flywheels and flexplates are 292 only as far as I know. I got that wakeup call on mine when I pulled the flywheel off so I could put it on the engine stand.
Sorry for not updating this sooner. We stepped up the flange on this to use either a 50,55 MM. BIG Weber Carburetor side draft inline 6 High Performance Manifold New cast Manifold modified and PRO Ported to accept 50 and 55mm carburetors. T6Perfromance is having them cast in the USA and they are machined in house in 4 different configurations for the L4 and L6 Inline Chevy 6. This manifold and all the ones that we will be selling are set up with USA made splined cross shaft and splined arms “they will NEVER SLIP”
Just found this thread. I had a 292 with I believe a 400 turbo in a 49-50 Chevy pickup probably 25 years ago. Ran really good. Drove it a lot. Traded my 40 Ford sedan for it, have no idea what happened to it?
I would like to know but am a little afraid to ask..how much will this complete setup cost? I have a 292 and this setup intrigues me..
We are still working on that, we are still working out the cost from the foundry. But this setup right will be much more than the others Due to the additional work that went into these ones.
I missed that when you posted it, My 292 is a 68. I sure like the looks of the Intake Twisted 6 is working on but have too much money tied up in the Aussie speed intake I have.
