I have 2.8 Cologne V6 out of an XR4i... I know its not the best possible tuning platform but I am seeking few more bhp before the engine will be put into a -73 Taunus as the old engine is dying. 2.9 and 4.0 V6's weren't really options, and neither forced induction as the car won't pass MOT then.

I already have steel exhaust manifolds for the engine, and plan to make stainless steel exhaust system for it. Carb will probably be 38/38 Weber and I reckon it could use some head porting as I've seen stock Cologne heads and they were horrific. When it comes to cam choice, would Pipercams 270 do the job? Im after nice fast road cam with lots of torque so no need to make ultimate high rpm hp.

With ported head, sorted exhaust good carb and nice cam, would I see power somewhere near 180 bhp and 250 nm? That would be enough for 1000 kg car as its just a cruiser not meant to do any kind of racing.
