There is no such thing as decent power out of an 8 valve.
Its good measure to have the BE3 refreshed if not already by Adrian. Hes know how to get them just right and will tighten it up so to speak. Lower FD as mentioned by rich. Or just use a VTS box.
Cams are not a big deal to tune. If you have a Haltech on it there is a few base maps to get u going then a final dyno tune when its on the road.
I run hall effect 60-2, in the normal hole. It works a treat.
Pat's car with it's 4.06 cwp and GTi gearset, is the ultimate combination. However, if you're heading to the track you need the 4.43 cwp.
Really you don't need all this work anyway just go and have some fun. The 405 is a stock DFW probably untouched since new and done 6 years of motorsport.https://www.facebook.com/raymond.ga...ehOAOdavEzkt5j6HwO8eWa6rYUGERLvOxpYPuu4yq1XPD
It gets real tight with the cast iron block if you want air conditioning, let alone the inlet and the condenser. The alloy is another matter I hope!
