Cause of clutch problem
This is a common problem with Tigers that have the original close ratio (2.32 first gear) transmission. First gear is too tall for starting out, especially up a hill. This leads to having to rev the engine to keep it from dying and burning up the clutch until you get the car going fast enough to let the clutch all the way out. This is really bad for stoplight to stoplight racing. What's that smell??? Hmmmm, fried clutch. To compensate Tiger owners used to put in 3.31 or 3.54 rearend gears, but then your engine would be spinning 3500 rpm at 70 mph... or they would put in dual disc clutches and high performance pressures plates thinking the problem was an inadequate clutch.
IMHO the problem has always been the transmission gearing. Even the factory realized this and switched to the wide ratio toploader for the MKIIs, while keeping the 2.88 rearend gears. Personally I run a wide ratio toploader with a 2.90 first gear and 2.88s. The hole shot is fabulous behind my 331 stroker, and because the mechanical leverage is so good with the low first gear, I get by just fine with a single disc Centerforce clutch and I can even let the clutch out at idle without the engine dying. And now that first gear is so low, I am going to install 2.72 rearend gears for a 6% overdrive.
