kits available for disc brakes
I started with a slant six car. Got a 360/727 and put that in but I only changed the radiator and driveshaft when I did the swap. I finally got a new rear end after 4 years of beating the old 7 1/4 and I still have not touched the breaks on my car. I eventually will upgrade to discs but as long as you rebuild your drums then you should have no problem stopping a v8 car. Plus I can vouch for the 7 1/4. I put the v8 in when I was 18 and went through some serious tires with that rear end and it never gave me any trouble at all. Just dont put slicks on it and you should be able to take your time and build as you go.
