Thank you all for the input. I always feel a little "warmer" response from the inline guys.
Geezer,
I think my dad just wants the dual carb setup for the "cool" factor. Plus I have 2 carbs, but just recently found out that they are different era's so it would be easier to find another of the correct year carb I have. Which isnt to hard or expensive.
Maydaymike,
Thank you! That's the kind of info I'm looking for. I knew there had to be a simpler way of identifying which blocks were common to each other.
Gmdad,
Yes, I know about this. We found a 292 with transmission pulled out of a 63 c10 on craigslist. Kind of good and bad. Good because the guy who owned it literally removed only what was keeping the engine and trans in the truck. So we got the mounts, adapters, brackets, and everything else that goes to the 292. And we know it to be the correct parts because the engine had literally never been messed with. It still had the factory pistons and main bearings in it. The bad was the guy who pulled it out wasnt the brightest. He took a sawzall to the header exhaust tubes about 5 inches from the flange. He also took his sawzall to the floor mount stick shifter.
just a couple of bolts and a press and turn of the shifter retaining collar and both could have been salvaged. Also, the block had about a 4" crack down side of the block below the intake/exhaust. So the block was junk. But we found another 292 from the guy who my dad bought the truck from so I actually have the bolts,mounts, intake, carb, water pumps, from 2-292 engines. So we have a complete 250, 2-complete four speed with granny low transmissions, and 1 good 292.
