250I6 swap to 283V8

['63MurderTruck]

Finally swapping my son's 1963 C10 -- I6 to a V8...

The I6 currently in the truck is a 250ci(not the original motor), it has a TH350 trans.

Any advance info or advice will be greatly appreciated.

I've read that the I6 motor mount has 3 pieces and if you remove the center piece, it will bolt up directly to the V8, with no need to buy new motor mounts. Is this correct?

Will the trans have to be moved forward or back, or will it remain in the same position? I'm just wanted to know whether or not we'll need to end up having the driveshaft lengthened/shortened.

Is there anything else that I need to be aware of, or on the look out for during the swap?

thanks

The 283 is out of my 1957 Chevrolet Belair, it has a standard trans... so, I'll need to use the FLEXPLATE from the I6 if it's interchangeable, because the 283 will be paired with a TH350.

Are the I6 and the V8 FLEXPLATES interchangeable?

Flex plate should interchange along with the starter.

If your 283 is truly from a 57 chevy it will not have provisions for side mounts. Look on the sides of the engine block for the mounting bosses. Chevy did not start using the side mounts until 1958.

Good catch.

Evidently the 283 was not original to my '57, because it DOES have the side motor mount provisions.
