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!
