I am wanting to do a SB Chevy engine swap into my 49 1 1/2 ton.Does anyone know if the after market v8 conversion crossmembers for the 1/2 tons will work in a 1 1/2 ton??? How about the trans crossmembers??? I am thinking 283 or 327 with a turbo 400.Mainly because I already have the engines and trans.
