Nice cars! I'm familiar with both of them. THe Cougar looks great. Have you had it dynoed with the SVT UIM and LIM?

As for the MGA, there is a site that deals with an MGA bottom end swap. I am not sure if yours is a twin-cam. If it is, the only way to keep the stock appearance and get more output is by adding the greater displacement of an MGB 3 main bottom end. with some minimal head work, the MGA head will fit on the MGB block. I am not sure if it is the same case with the MGB 5 main engine. Then you can rebuild the MGB blcok to about 1900cc. With single cams you'd be looking around 90 crank HP. With twin-cams, probably closer to 110 or 115. But I am speculating.

I'll try and find that link for you when I get home.

Have fun! And email me any time. I love talking about these old cars. I am looking to do a Ford Zetec conversion in my 79 MGB roadster....
