I would not go out as far as 1 3/4 primaries. 1 5/8 will do up to about 500-550 bhp on an SBC depending on the rest of the build 1 3/4s are ok for about 750 to 800 bhp on a BBC they really are too big for a rover without a blower to help. From Tony's earlier post it looks like he has a set sorted, can't you get them from the same place?
I am on 2" primaries on my SBC build, but originally I was going for a cross over type manifold with it, now as I said earlier it will be open primaries and methanol, later to have a blower and I am not fussed about throttle responce of Idle or driving in traffic.
Shame it is for the road, you could have done a full length Megaphone exhaust in 2 1/2 pipe and some flat stock, would have sounded wicked!
I think the side pipes and a ballance pipe might be the best answer as far as getting it all in, cant dump the fuel tank and stick a fuel cell in the boot?
