?Darling, as far as I know you use the amf or bhc flywheel and corresponding clutch kit but I think there is a spacer you leave out. A recent thread in here saw someone to the same solid conversion without issue.
As many forum members run remaped 75s taking them to around 100 bhp without issues this clutch set up is tried and tested comfortably over your standard 90.
So unless your a harsh driver I would seriously consider the conversion
Honey, have considered that route and had various views expressed as to how good for road use. Any advise as how to do and part numbers would be appreciated.
