Team,
eminent smart guy David Vizard says to use 1 sq" of intake scoop
opening per each 20 to 25 HP normally aspirated.
Dick,
I am currently rebuilding a Daimler 'Hemi' V8 for a friends 1963 SP
250 Dart sports car. Yes they are a gorgeous little mill. They are 2.5
litres and a rarer 4.5 litre. Originally designed by the same english
gentleman who did the Norton twin I'm told. Some obscure features is the
cam mounted up in the valley with the followers placed horizontally and in
bores on the underside of the valley cover under the inlet manifold. Short
horizontal aluminum pushrods leading to miniature looking Mopar style
rocker shafts and stands. There is a bloke in the UK who runs a 2.5 in a
digger. Roots blown on fuel it makes a claimed 1400 HP.
A very obliging clever man whose name and phone I will forward if you want,
(and I can hopefully find).
He informed me that bottom end bearings last a season with that output, the
original oiling system is that good. I don't condone cheating but imagine
being tech'ed or checked on a dark day. You could claim the little donk,
down to 1000 HP for Bonneville, was merely an Ardun flattie (XXF) it looks
so similar. I know it would definately catch the attention of some on this
list. Happy hunting.
