Both trucks have the enclosed driveshaft. | | | | | Joined: Dec 2001 Posts: 1,248 'Bolter | | 'Bolter Joined: Dec 2001 Posts: 1,248 | The bellhousing from a newer 216 would probably bolt to the older engine, but I'm not sure if the transmission pattern is the same on the original housing or not. I remember some one saying the older transmissions were shorter in length and the enclosed driveshaft is longer on the older trucks than the AD.

I happen to be trying to get one on a 235 in the prep stage now. Glad you thought of this because I sure didnt. | | | | | Joined: Dec 2001 Posts: 1,248 'Bolter | | 'Bolter Joined: Dec 2001 Posts: 1,248 | if you have the bellhousing from your 216 engine, it would probably swap on to the 235 engine, so your older 4 spd will bolt up. | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 |
