Hello,

I got a 51 1/2ton cab and frame with the original 216. I just bought a 235 out of a 61 impala but it has side mounts and also has the powerglide tranny, I dont want to have to change out my rearend yet so I'd like to keep my 3 on the tree. What I need to know is if anyone knows for sure if the flywheel on the 216 will fit on my 235 and will the front motor mount on the 216 bolt onto the 235 so I can mount it in the truck.

Thanks,
Dave

The '41-'54 flywheel bolt pattern will bolt right up to the 235 crank flange. That's the flywheel I used when I put a '55 235 in my '40. I'm not familiar with the side type front motor mounts.

Thanks Steve, I dont know if you noticed but thats the motor and trans you posted!

The front mount plate should bolt right on too but it's not as easy as it sounds. You have to pull the valve cover and rockers to remove the lifters, pull the oil pan to remove the timing gear cover so you can pull the cam to replace the plate. Nothin' to it.

Before you go back together you might as well do The old timing cover trick.

I just went out & double checked my motors. I have two '62 & one '60 235 sitting in my garage & they all have the front plate. I personally pulled these motors w/low mileage from the cars. Well, except for one '62 which is still in my Belair. Yours should also have the plate. All you have to do is drill the mounting holes in the plate. I guess Chevy kept putting the plates on so they didn't have to redesign parts, but didn't drill holes to save costs.
You also want the 216 flywheel to keep your 6v starter. They have different tooth counts.

Dave,

I thought it sounded familiar. I hope it works out well for you.
