What about a Lotus Twin-Cam engine that they shoved in ye olde Mk 1 Escort/Lotus Cortina
Nice engine btw! Is it actually streetable (legal emissions) or you just more concerned with getting it going at the moment? Also, you may want to look up some of the running in the engine info in the tech section. Running in an engine and doing a dyno run aren't mutually exclusive! In fact, after the first 100 kays you should be able to chuck the thing on a dyno.
Btw, did you tune the carbies with the trumpets + socks? Because if there is a difference in the air flow then it can actually cause leaning out (my brother's rally car had that problem and boy did it get toasty!).
