I recently read an article in Car and Driver (1996 issue) that stated the LT1 engine was the same (performance wise) as the LT4. Thay stated that 0-60 and quarter mile times were identical. The only difference was an increase in top speed of 7mph. Needles to say they were very disappointed. Has anyone driven both....are their findings correct or is there really a little more punch in the LT4. Please let me know because I'm considering buying a LT4...however if there is really no difference I'll get a LT1 and save a few bucks.
