Re: Which Gearbox behind an XE 351c
I'm running an 11 inch RAM pressure plate on a billet steel flywheel with good ARP bolts. You don't want that thing letting loose at full RPM. With 400 poines I'd definitely make sure it's beefed up - good insurance.
The clutch is stiffer than a Hyundai but still OK to slap it thru the gears in quick time. I agree with everyone else - if you go the manual, go the toploader. Otherwise you'll destroy the cheap 5 spds on day one!
Your total weight seems a bit high. I took my XD down to the local tip and weighed it on the scales - 1670kg with me in it and 1/2 tank of fuel.
