Thanks Vista and Eeb43.
It's a Ford 302 small block. I know that the Rover 3.5 is more common but I wanted to keep it Ford [even if it's not technically a 'Capri' any more].
302s were indeed in the SA Perana but had highly restrictive cast iron manifolds meaning that each port probably had an inch at best before collecting. The engine that I've put in is NA with a 4 barrel carb, producing 400+ engine BHP. For all of the effort, time and money etc to do the engine and get it right, I don't want to choke it.
I'm based in the NW and the Capri has gone to Cybox on the Wirral. You may have heard of them under their old name 'Peco': I remember Pugs, Escorts, Renaults etc all running around with Peco stickers back in the 90s - it's them.
They seem like good guys but have said that they [like a lot of exhaust companies], build from the manifold out, they don't fabricate manifold set-ups. That said, they'll have a go but it's likely to be expensive!!!!!
I suppose I was just hoping that someone who'd done it could point me towards a set of tubes that may need amending/bashing slightly, but will be cheaper and quicker to amend than making from scratch.
That, and obviously Lockdown makes getting around and talking to people impossible.
Thanks both - appreciate your time!
