The Mulfab set up is fantastic, as you found on your Dad's Plus 4. Plenty to get stuck into by the sound of it.

Looks a well planned project that will lead to a fabulous end result.

  So far it's all been cosmetic!

Quite a lot! Stroked to 4.6, top hat liners, pocketed pistons, stage 3 ("Monster") head porting with larger valves, fast road cam, intake manifold ported, intake trumpets shortened and widened, throttle body ported, lightened and balanced flywheel, heavy duty clutch. I have already upgraded the injectors to Bosch ones and have the Tornado ECU re-map.
Aiming for around 290-300bhp. I've spent quite a bit, but luckily with my own workshop, I don't have to pay any labour charges!
If you compare it with a 3.7L roadster, I think it looks really really good value for money...and will sound better! With serious HP it might be time to consider Suplex,s coil over rear suspension in order to get the power to the road. I drove a +8+ (Corvette engined) Morgan with a coil over rear suspension designed and built by Bill Fink. Actually used this +8+ on a 4 day "Flog Mog" in Northern California. Too bad I was not a better driver. The +8+ was GREAT!

That is certainly something to consider, although I wouldn't want to do that until I have driven one with it.
Although the engine will have a huge jump in power, it is still controlled by my right foot, and I haven't had it tuned to race or drive like a loon... just to have plenty in reserve... like a bank account, you don't need to spend all your cash, but it is nice to know it is there!
