A number of stroker kits or short block options are available in the USA. I realise that the engine management module will have to be re-mapped and a dedicated tune installed to cope.
Anybody on this forum had any experience with 370 or 390 stroker kits for the 5.7 Hemi or know of a tuner capable of writing the software for same ?

Rod, if your going to be a Bear, might as well be a Grizzly... Buy the 426ci short... 7 litres, no less.
The engine is easy. The problem you will have is with engine management.
You will need to add a piggy back ECU. A stand alone ECU will not run your trans, so leave the standard ECU in place and only tell it what it needs to know to run the trans, the engine can then be controlled with an aftermarket ECU as a piggy back. I have only had experience with Motec and Autronic, whilst these are the best, they could be a bit pricey, if so, I would contact Haltech for the ECU. You will not get a tune or file to work with the Export ECU we have - period, and just adding larger injectors will not work.
Do not get sucked in to running a Chip type piggy back ECU. Contact either of the three I have listed or Link G4, nothing less. Cheap is a short term fix for a long term problem.
Also, be prepared for a long road. You need to be able to roll with the punches and expect problems and issues. If this is not you, dont do it.
I'm sorry if I have come across a bit preachy, I have extensive experience in this field and am only talking from seeing this sort of thing work well and fail miserably.
If you are looking for someone in Perth who will not mess you around and will tell it how it is, speak to Mark at Marks Workshop in York.
Anybody installed stroker kit for WH 5.7L Hemi ?
