[Tigers] 5 bolt 289's

[Larry Mayfield]

The next motor for the race car will be a true 289.  I have purchased a 
mexican block which is supposed to be stronger, and I have found forged 
4340  289 crank, rods and some good pistons.  WIll reuse my expensive 
race parts, i.e., heads, cam, lifters, rockers, etc. Am gooing to try 
and get a real intake manifold though unless it is too tall.  A 
Profesional Products unit with injector bungs in the right place.  The 
record for that engine size is 222 so maybe I can attack that. If not, 
then that motor will replace the 260 in my real Tiger for putting around 
town. Gonna try and get 650 hp out of it.  Lots of boost. If Jerry P can 
do it, maybe I can too!
