If driven sensibly they will be fine behind a 253 or 308. Just like an aussie 4spd, easily broken but will last if not abused.

To use the box behind a V8 you'll need a bellhouing, clutch plate and might need a tailshaft mod, the one in this ute may have the Celica yoke with Holden uni on it but is possibly a 6cyl one. Crossmember will need modifying too as relative to the 6cyl location the box will move forward by the difference in length between a 6cyl and V8 aussie 4spd. I have a 253/308 to Celica bellhousing and clutch setup at home, but it has longer bottom bolts being a Dellow one so only really useful for HT-HJ as if you try to use it on HX or early HZ you have to wreck the rat-trap as it attaches using the lower bellhousing bolts.
