[Gunster89]

alright so I had life kick me in the butt and know my 66 gmc big block swap is on hold for a year or so curently I have a 292 in my truck I have a small block 305 im going to put in the truck temporarily because I miss driving it ive been told the transmition will bolt right up to the small block and I have to move the engine mount up a bit will I have to do anything else to make this swap work? will I have to get the drive shaft extended / shortened please anyone who has done this swap help the 292 is dead so yea I havent driven my truck in over 6 months and its killing me I want to drive it if you know what I mean

Yes a small block will bolt right up to your bellhousing. The 292 flywheel should bolt up to the 305 as well. As for the motor mounts, you will need a passenger side motor mount bracket to bolt into the rear location to match the drivers side. The 292 uses offset motor mounts. If you don't move the transmission, you do not have to do anything with the driveshaft.

Beware of the part about the flywheel bolting up. Every 292 I've ever had used 1/2 flywheel bolts instead of 7/16. If that's the case, the holes will be too large when you bolt it to the small block and it will wallow around.

You will also need a clutch bell crank pivot ball that screws into the side of the block, NAPA can get this for you. If you are using an HEI ignition, you will need to run 12v to the dist. aaaaand make sure your 305 crank has a pilot bushing installed, if not (probably not) you'll need one of those.

Thats pretty much it

Thanks for catching that. It's been a long time since I've had a 292 out.

oh well now I had a sbc 400 drop in my hands is there anything different from above needed? and yes its got hei and what does this clutch bell crank pivot ball do exactly is it basically the support for my clutch pedal?

The 400 will bolt in with the same changes mentioned above. 400 sbc's are externally balanced so you'll need an appropriate externally balanced flywheel.

A new 292 flywheel from Rock Auto which the manufacturer does note has 1/2" bolt holes
ATP part # Z295 which costs 75.79 plus 12.66 for shipping to Prescott Arizona.

A new 400 small block flywheel from Rock Auto which the manufacturer notes is for external balance engines
ATP part # Z294 which costs 72.79 plus 12.93 for shipping to Prescott Arizona

I cataloged the 292 flywheel for a 71 model C20 truck with a 292 and the 400 small block flywheel for a 74 model K20 truck with a 400.

It supports the bellcrank (Z Bar) that mounts to the frame. The 6cyl will have a bracket with a welded ball on it and the V8 uses a stud mounted ball that threads into the block. (I assume all V8 blocks have the threaded boss for it but I would check before intalling engine)

Here's what you need:
