Someone has a deathwish :o A long time ago I supplied a John Eales-built 4.6 with 283 bhp to an TR8-owner and the general consensus was that was pretty much pushing it in that chassis...

Thanks to the Lloyd Specialist Developments Ltd team for the continued support!!!!

Wow! No other engine modifications?
