RE: 396 in a 72 Z 28?
[sm=noooo.gif]sorry to point this out but you are wrong, LT1 was originally a designation for a high-performance, fully forged, solid lifter race motor designed for the trans-am racing series and detuned for the street, it carried 11:1 compression in 1970, 9:1 in 71 72, and i think 73, it was also the highest performing small block in corvettes, it was rated at370 hp in corvettes, and 360 in maros, then 330 when the compression change took place. the LT1 name was used on new gen 2 small blocks as an homage to the original, just as the LSseries looks back to the original LS big block series in the late 60s early 70s. ALL Z28s from 70 to 73 had this motor, as well as either a Hydramatic 400 or M21/22 4 speed. All were either geared 3.73 or 4.10 from factory, and all were ac delete until the 73 model year

i'm thinking about buying a 1978 Z28 without a motor and tranny. What is the best option for a newdrivetrain for this car? I don't want to go with the '78 Z28 350, seems it was weak on hp.
