67 GMC 305 V6 swap to a SBC 305

[bigwil86]

Hello all, Im new to the site but none the less love these old trucks and have since before i could drive.

Yesterday I made a purchase on what i thought was a GREAT deal on a 67 GMC C15/1500, swb, fleetside pickup truck with the 305v6 and 3 speed on the column. Not until i start thinking about doing a sbc swap that i realize i maybe in a little bit of a pickle. Im at a total lose on the swap and no clue where to begin.

Would it be possible to cut the frame off of 73-87 frame right in front of the fire wall and have it measured up and weld into place on mine after the removal of the front section of my 67 frame. The 73-87 frame would allow for disc brakes, spindles, sbc motor mounts and eventually allow me to install airride suspension a bit easier, or would it just be simpler to swap the crossmembers?

Any help would be greatly appreciated, Thank you!!! Wil
