need help/info to do a 5.3 swap please hello i am getting ready to take on a 5.3 swap into a 63 buick rivera.the guy has a complete engine and trans,harness,fuse box,ecm and a box load of other stuff.i need help figuring out what "gen" the engine is.im reading certain ones are not worth the swap cause of gas pedal and ecm.but i dont know thats why i am here. online this looked like the best ls info i can find i hope.i took some pictures of engine and trans.but the #s i have dont match what im finding on the internet.on the back of the cast iron block is a # 12578181 behind left cyl head looking at the engine from the front. on the cylinder head is a #7109025610 .the transmission has a tag on it 8DCA 24226651 below that YTO 7159 below that 618DCAHB343428 .just trying to figure out what im working with and if its worth doing with the engine and parts.we already have .thank you very much
