Also most of the parts of compatible to upgrade older LS1's such as LS6 clutch and oil pumps, LS7 clutch,Lifters etc.. Also the LS1 is already 10 years old if you didn't know. CASE CLOSED....

The LT1 is loosely based on the Gen I small block, only the Gen II's had a reverse cooling system and more advanced fuel inection. Outside of that, an LT1 block looks no different then an L98 or any other SBC 350 made since the 50's.
The Gen III engines were an all new design. They share nothing with the Gen I/II engines outside of bore spacing.
The GenIV engines are an upgrade from the Gen III design, but the L92, LS3 and LS7 have a totaly different head design. Gone are the cathedral ports of the GenIII and early Gen IV V8's, back are the more traditional rectangular ports.
The L92/LS3 and LS7 heads flow tremendus amounts of air from the factory, and the LS7's heads are CNC milled and hand built...some say by people, some say by God.
Oh...and Third Gens > 4th gens. If it wasnt for the LT1/LS1 combo's, GM would have sh*tcanned the Fbody in 94.
