Re: 350 to T18 bellhousing?
Lakewood makes a bellhousing for a Chevy 350 to Ford T - 18. The Lakewood bellhousing is even more expensive than AA. Most likely your not wanting that option.
The GM/Pontiac (Iron Duke) 4 cylinder bellhousing used in the early 80's CJ's will bolt to a 350, and once new holes are drilled and tapped into the Iron Duke bellhousing for the T-18, the Iron Duke bellhousing is ready to run with a hydraulic clutch. This is an affordable option. The GM/Pontiac 4 cylinder bellhousing has the T-18 mounting bosses already cast into the bellhousing, just need to drill and tap the mounting bosses. Now for the news you might not like, the GM/Pontiac 4 cylinder bellhousing allows the use of the smaller 10.4" Camaro clutch. GM pickups used either an 11" or 12 clutch. If you don't mind using a car sized clutch on the trail, then the GM/Pontiac 4 cylinder bellhousing is an affordable option.
Next option, the Ford T-18 input bearing retainer could be machined to a smaller diameter to fit the large center hole of a GM pickup bellhousing. Next problem, GM pickup bellhousings have two different sizes for the large center hole. The SM465 uses a large center hole of 5.125". The other GM pickup bellhousings have a large center hole of 4.686". The Ford T-18 need's a bellhousing with the large center hole 4.848". The Ford T-18 input bearing retainer could also be machined to allow the use of a GM throwout bearing. Modifing the Ford T-18 input bearing retainer is an affordable option. The top two holes on a GM pickup bellhousing are 8.250" apart. The top two holes on a Ford T-18 are 8.500" apart. Just elongate the holes in the Ford T-18 so the holes are 8.250" and the top two holes of a Ford T-18 will bolt up to the GM pickup bellhousing. One of the lower mounting holes of a Ford T-18 will not mate to the flat surface of the GM bellhouing, let's hope your Ford T-18 has the extra mounting hole between the top and bottom mounting holes. Then just drill new holes into the GM pickup bellhousing for the T-18 lower/middle mounting holes. The lower/middle mounting holes of the Ford T-18 will be blind holes in the GM pickup bellhousing, which means you will not be able to tap treads into the GM bellhousing.
