Is this a small pad or large PAD Block ? The True XCH LS7's are from 1973-1976....with large front stamping pads. Using 2nd Gen L88 Rods 180 ZL1/L88 Cams...pushrods rockers etc. the later ones are the Generic type that Chevy marketed as LS7's , L88's & LS6 Crate motors ... assembled with the mass produced Truck type blocks , Rods and Cranks...using small pads.... Check the Casting #s ..freeze plugs and pad. An early 80's purchase can be either one....All the 90,s Engines are Early Period INCORECT in appearance and content!!!! Don't be fooled with LS7/L88 monikers the Real Ones are Early builds and have the "RightStuff".
