[Fot] 89 mm liners in a street TR4

[EDWARD BARNARD]

Randall: Although I left everything down below stock, I'm sure the car could
really come to life with some head work. We're talking stock rods and crank
with a stock high port head with stock manifolds and carbs, atop a stock
block. The Babe Erson cam (Larry wasn't doing his cams yet), with Ken's 89mm
kit and Joe's lightened flywheel. The block needed no relieving at all. The
car is here in Texas so cooling was a fear, but, not a problem after all. I
did my normal mods...stock TR3 cooling fan with a modern stlye (non-sleeve)
160 degree thermostat and the bypass pipe in the thermostat housing blocked
off to 1/4". The car has never showed signs of getting above the half way
point on the gauge even in the summer. This car can show in concourse because
none of the mods take away from the look of a stock "3"

Thanks for the info, Ed.  I'm planning something similar myself, except with
a little headwork; 4-2-1 exhaust & Larry Young's street cam; so it's good to
hear it works out.  Ken seemed a little worried about cooling with the 89s
on the street.
