I like the idea of 2 unevenly size inlet valves and one big
exhaust with sparkplugs on each side much like the Mercedes
and some other engines. I think 3 valves are plenty.

Great piece of work though those aro heads, If someone
can afford to go that far perhaps rotary valves would be
better if guaranteed the sealing wont be an issue.

You can always use 4 valves on the Chevs with pushrods using the ARO heads

If you got enough coin

Dundee 4 valves to 3 my kind of thing.
I love the 3 valve heads especially if they are for pushrods engines!
Pity chev dumped the progress of the variable 3 valve pushrod smallblock.
Only Barry Grant has a strange looking 3 valver now.

thats my Boss's Top Bike,
little changes all the time to keep you on your toes..
4 valves to 3, change the stroke,
clearance the block, support bearing here..

it's all good fun though..

oh year that's a nice piece of engineering ,only that it has no water jackets , straight line stuff only

What about a Top fuel Bike motor... yum..

I could go the china option, itll cost about 1000aud but wont fit anything
except the recycle bin :)

I suppose if you are going to go through this trouble of using 40kg of billet
alloy then you might as well aim for the v8 option.

As for most cars here only worth 1k surely they are worth more than 4 year old Taxis :))

yeah darrens right if any of us could afford this setup we wouldnt be driving dattos

haha darren is my car worth $1000 lol

D you would go chev bell housing bolt pattern as you can get heaps of off the shelf bell housings
Ward the guys on here have $1000 cars mostly. itll never happen

$8500 is roughly 80 hours of 3d design and 4/5 axis cnc programing and machining ($250.000.00 machine ) then you have the cost of the alloy billett (6061 is $9/$12 per kilo)and you start with say 40 kilos and machine off 30/35 kilos and that goes in the scrap bin. $8500 may sound like a lot of money but if you did this same project in australia and on a one off baisis you wouldn't get much change out of $20.000.00. Go the american option they allready have all the bugs sorted out .
