Just stumbled on this thread, I like guy's like you that do something a little different, but just wondering what engine management system are you using, it's just that the ford system is a bit crap also the engine runs on 12 of it's valves most of the time being controlled by a butterfly system in the lower manifold which holds them back a bit.
I've just fitted one of these lumps in to a MK1 Escort on a Sierra floor pan just to give everything a bit more room, but converted all the management to Microsquirt system, the difference to that engine is unbelievable
