I could help you out with this Chuck. I will get you what you need.
The same kit I sent to Canada and sending to Manny made 1134wheel hp on a 426.Cheers junior, was your mail order kit hp results with a 426??
chris is the man if you looking for this set up!!Ok really need some help with this, with an arrington 426 engine would you still be able to add heads cams etc, but would they add significant hp to the engine, really debating on creating 850hp+ beast with twin turbo.
