I have a '51 RT Flathead Ford engine I am going to put in my '29 pickup. I would like to use the origional 'banjo' rearend. I heard once that they are not strong enough for the added horsepower, infact the four cylinder tears them up easily. I talked with an 'old timer' (only about 10 years older than me actually) who told me that's BS, that he used to race with the same rear end in the '50s and never once tore one up. Who's right? I don't plan on lots of horsepower, just going to run the flathead stock, maybe headers. I'm putting a t-5 behind it so I'll have to convert to open drive. Any advise?
