Can someone help me out I'm looking to install a Rover V8 into a 57 MGA .This is my first sports car but I have been rebuilding cars for A long time. I know I have to change mounts both motor and tranny. But not sure if I have to modify the firewall they radiator support that sort of thing. I read about the MGB Front shocks and I do have a donner MGB for parts. I just cant seem to find any information on the builds that people that have done the conversion just pics. any help would be appreciated. And I already have the rover V8.

There are a couple of Buick 215 conversions in the photo gallery that could help you, also a V6 Buick that could be some help. Those have a list of mods that could help.

John Mangles could assist here. He did a 215 conversion on his MGA as did John Hubbard and Lyle Jacobson.

I would not do it if you have good, solid car. Gotta hack it up pretty good to fit.

It can certainly be done but it is quite a bit more work than a V6 is. You should consider the V6 route (which I have done) and if your power goals aren't particularly high (mine is c. 200 bhp, maybe 20 bhp more than a stock Rover 3.9) it would save you money and work.

See [www.rhodoworld.com] and [www.britishv8.org] for pics and some write up on the conversion process.
