WHAT THE EXPERTS SAY (page 2 of the brochure)
"As a conversion, we rate this car as perfect and as a
model in its own right it deserves the highest praise."
"...and the whole car much more refined to ride in than
any MG built at Abingdon."
AUTOCAR ROAD TEST (25.2.72).
"a smooth and quiet surge of power that transforms the
car so that it can compete with cars costing thousands
GORDON WILKINS (Sunday Observer 3.2.72).
"One of the nicest cars I have driven."
JOHN LANGLEY (Daily Telegraph).
"The result is an MG which, as I discovered last week
contains all the tigerish acceleration power and speed
you would ever need, with kitten-like docility and
MAXWELL BOYD (Sunday Times 25.7.71).
"Everything is so quiet, we even started to criticise
the quality of reproduction from the radio and, quite
truthfully, in top gear at about 30 MPH, not
accelerating, there is not a sound to be heard."
AUTO ENTHUSIAST (August 1971).

light yet positive steering, giving improved road

Note: between 1972 and 1974, Ken Costello converted approximately 200 MGB's (mostly GT's)
to Rover aluminum V8 power. His production rate declined after that, but he continued to
develop design improvements and features, and to convert more cars to V8 power over the
next twenty or so years. The two photos above, from Jake Voelckers' collection, shows an
early Costello MGB.V8 with dual SU carburetors and the accompanying large hood bulge
