Ford with different bellhousing or some gearset, those are options i consider.

Btw. Some ppl, says 5.xx f drives dont last long. Does anyone knows for sure maybe?

Quaife,Xtrac and tranX Ford type9 gearboxes can be found for 1000€ sometimes (used) and don't have to be too expensive newly rebuilt. That would be the cheapest way to straight cut gears and bespoke ratio's. Adapter bellhousings are 200euros or so.. Still ads up to $$$$ though unless you get lucky.

The higher the final drive ratio, the more teeth you need on the crownwheel and pinion, the smaller the individual teeth get. That makes them weaker. 6.4inch crownwheels with ~3.0 ratio will last a long time even with 300+hp.
