    I'm getting a 81 that had a 292 cyl and I'm going to be putting a 350 in place. I did this swap on my 65 c20, all I had to do then was change a bracket on the frame because the 292 engine backets were offset. Would it be similiar on the 81?

    yup!..

    The brackets are set up the same as the 65 was,though they probably are not interchangeable with newer years...73-87 frames are a bit different than older years,but are close..all you'd have to do is move the brackets to the holes in the crossmember that they use for V8's,and bolt them up..the passenger side bracket might not work from the 292,you may need to hunt down a V8 one ..

    (I'm a bit fuzzy on this,I only swapped one 292 for a V8 many years ago,and one other truck I put a 292 in place of a 250 six,and had to find the 292 passenger side bracket)..but I used the ones on my 79 C10's 250 six to bolt in a 305 with no changes..

    The 292 was no gas mileage champ,but their low end torque is impressive.(it put out its maximum at 1600 rpm!)...my older brother had a 66 K20,with a 292--we put a 350 in it,and it didn't plow snow half as good as it did with the 292--the 350 wanted to spin the wheels and axle hop badly,while the 292 would just lumber along at fast idle nice and smooth..maybe it weighed more than the V8 too?..--don't toss the 292 unless its got holes in the block--many folks find them desireable,and cores are hard to find now!..:crazy:

    I miss the 292 I had in my 65, I swapped that out back when I was in highschool, I do remember it being a torquey engine and it looked huge compared the small block that replaced it

    The 81 I'm getting has no engine, tranny, t-case, and axles. I'm taking everything out of my 77 K20, the 81 was a k30 crewcab with a 292, th400, np205

    Yo, if you still have your 292 motor towers (frame brackets) I want 'em (right side especially)! Will buy outright, or swap for V8 ones, cleaned and painted. Got a '79 K10 I want to drop my hot rod 292 into...

    I'll take the HEI setup if you are pulling the engine!
    PM me!

    I want to install my rebuilt, hot rod 292 (now 302), from my '68 C10 into my '79 K10, but the frame/motor brakets aren't interchangeable. The 2WD ones mount to the front suspension crossmember. The right side motor mount on the 292 is 3.75" forward of the SBC / BBC. The frame has holes, drilled, but the existing one can't be moved up; it hits the cross member and I don't want to gerry rig motor brackets for the tall, torquey 292.

    You can get an HEI from Langdon's at:
