Jack,
Thanks for doing the work to check out the ratings and explain the
differences in WC. I guess 175 ft lb. ratings I have must be for the 4
cylinders. My Chevy literature shows 3.7? and 4.03 first with no distinction in
rating. Is the 94 Cobra that Jim say's you can swap innards on a electronic
speedo model? Might keep my eyes open for one at the swaps.
Thanks, Grant
