Just got done reading the new 4WHEEL & OFF-ROAD. There's an interesting (especially since we are getting to do the same thing) article in it about putting a Howell TBI on a 401 in an 79 Cherokee Chief.
They state it was a "built" 401, and they dyno'd it before, with the carb, and after, with the TBI. With the carb it produced 168.47 HP/238.81 ft. lbs. Talk about disappointing! With the TBI, it did 181.30/258.89. At least it was an improvement! (I had heard or read that we might experience a loss of power with the TBI, although better starts, response, mileage, and off-camber performance.)
The Jeep belongs to Jeeps R Us, and they didn't elaborate on what "built" meant, but those are some really disappointing numbers. Now I know I don't want to put ours on a dyno, especially after the amount of money we just poured into the engine having to do 2 complete rebuilds in just 300 miles!
Anybody else see this article and have any comments?
