[Tigers] 5 bolt 289 ?

[Thomas Witt]

Allan,

  I have a 5 bolt 289 in my early Tiger.  I did not put it in, so I can't 
tell you everything involved.  But having studied the install I will offer 
the following:

1. Yes, you will need a 5 bolt bellhousing. There were two types of 
Toploader bolt patterns. My early Tiger was the narrow type and I believe, 
but am not 100% sure all Tigers were.  My guess is that the 5 bolt is only 
the narrow type. The only issue might be if your transmission/bellhousing 
was replaced with a wider type mount. Given that you are asking about the 5 
bolt causes me to speculate that you might have a 6 bolt???.

2. The fuel pump block off plate transfers right over, or is bought from any 
speed shop, or created with a plate of aluminum, a saw and a drill (and file 
to make nice).

3. I am lead to believe that the Tiger has a less than common timing chain 
cover/water pump housing for radiator clearance. How that transfers over 
correctly  from a Tiger to a 289 I can't say.

4.  My understanding is you will need to use the Tiger pulley system for 
clearance.

%. The only other things that come to mind are the generator, oil filter 
mounts and the dip stick.  Sorry I can't help you here as I have an import 
alternator and an angled block mount filter.

  Hopefully there are others with more experience that will reply.
