MG MGB GT V8 Factory Originals Technical - Help me with my rear end ( selection )

I'm about to proceed with my MGA V8 conversion and have heard people talk of using a Volvo rear end assembly. My questions are, which Volvo, disc or drum brakes, what gear ratio, and what do I do about the master cylinder for the two ( MG / Volvo ) different braking systems? Thanks in advance, John

Hi John,
I'm glad to see someone else is trying this too. I have a '58, drum wheel car that I will be switching all the suspension and brake components from a '72B. That way the B dual line master cylinder will match up to everything. The axle is a tube type but can handle up to 300hp per what I have seen from Jim Blackwood. It bolts right in and with a 0.63:1 T5 the revs should work out fine on the road. Another option is a Jeep CJ-5 axle that can be made with posi and disks in a variety of ratios without the need to shorten anything. Right now I pulled the body off and just am looking at motor mount options. After talking to a few other similiar A's, I will target not to cut the goalpost and will have to move the rack a couple inches forward. They did this in the Twin Cam too without any bump steer. I need the leg room too at 6'5". I had a friend even talk with the guy in England that did the silver LeMans car and he moved the rack too. Let me know your plan of attack.

Scott, I already did that conversion without the dual master cylinder to my 60 MGA with a 1950c.c. MGB engine. It was an easy bolt in conversion. However, I think I would like to try the Volvo, disc brake rear end this time. I'm looking forward to the V8 conversion on my 58 MGA rust bucket but, I think I might be able to do it without cutting the goal post section back and moving the radiator forward and angleing it. I'll let you know how it goes.

John....I can no longer resist....
