Pat I forgot to ad I'm currently planning on useing a turbo 350 I got it has around 3500 miles since being rebuilt has a shift kit thats it it was in my father-in-laws street rod, with the previous questions regarding a 496 can this be used in my model-t or will it break right away and if it won't work with the 496 then how much can I do to my 454 to use it?
