Raff,I hope your tranny is up to the task. When I went from our 493 to 572 we started to tear up the front planetary(multiple times).This is launching off of a brake at 4500 rpm. Got a little smarter and After a bunch of A&A parts we got it to hold together. Big motor= lots of torque!
My 572 with Alum rods oil pressure is 80 cold and after a pass is down to 28-30psi at about 160-180 temp. I do have an adjustable pressure spring and single oil line that has worked fine to 7000 for the past 8 years.
Mike Hi ! Thanks for the info ! i have adjusted now the screw 2 turn and oil pressure at 180f is 40 at idle and 80 at over 3000... i think is good with aluminium billet pump and single External line , i have also a dual line kit....but very hard install with stock engine mounts ... this is my trans specs : billet steel front drum , 5 gear planetary front and rear front and rear solid bands Full Manual v body .. no trans brake ..billet pistons with 4.2 lever big aluminium oil pan 5500 converter

Turn the bypass regulator spring pressure up so it has the same amount of oil pressure as you shift it at(IE 70 lbs at 7000 RPM, 80lbs at 8000 RPM) or max RPM in high gear   I don't think I'm brave enough to run that little amount of rod bearing to crankshaft clearances even with aluminum rods cold  I like and use the old rule of .0010 for each one inch of rod journal diameter In other words I would shoot for a minimum of .0024 for stock Mopar rod journal size of 2.375 and .0022 on BB Chevy rod journals. I have and like to use .0030 + oil clearances on my race motors with steel rods on either journal size with no problems at all, .0035+ on the mains   AKA aside, when it comes to high RPM drag race motor looser on the bearing clearances is far better than a tiny bit to tight  IHTHs  That video looks just looks it was taken here in the U.S. it must be very hard to duplicate that look over there  Does Italy still have high import duties on American made cars and car parts? I was shock at what the Aussie and Fins have to pay for are cars and parts

I spent 9 months in Germany in 1968 in the Army, that assignment made me appreciate our country so much I can't say it in words Most people born here do not realize how well most of us in this country have it I have sold several of my old race cars to guys over seas, one is in Finland, one is in Sweden and one is missing in action on the sly  Dang the tax man anyways

Very nice! I'd be scared of running only 100 octane in that motor. My 14:1 Indy headed wedge motor likes being run on VP C12. On nitrous I'd be running at least C16.

 C14 min. Don't ask me how I know...  Engine sounds great though, bet it would idle a little lower than that... Not to appear pedantic but I think Europe uses a different way to rate octane numbers. IIRC I think 100 octane Europe is equivalent to 107 (ish) Stateside. Still not enough IMHO though.

Is it legal to buy and use that race fuel on the streets? Or is it only legal at race tracks? Do you know how much of your fuel prices are for taxes? I was stationed in Germany in 1967-68 and G.I could buy books of 200 liter fuel coupons books at Post Exchange for right at .21 cents a gallon for regular and .23 cents a gallon for the premium gasoline. That was a little bit more expensive than I was paying for the same brand of fuel in the states in California back then The German citizens paid between .91 cents and 95 cents a gallon for the same amount of volume in liters at the same pump We where told that G.I didn't have to pay the German fuel taxes per liter that the Germans did

Hard to work out how the engine gets enough air past them butterfly's at idle, almost look closed.
Nice job Raff, sound great .

As long as the duty has been paid you're good to go. It is cost prohibitive though. Typically, at more recent exchange rates, it works out around $30.00 a US gallon. I've never heard of anyone ever having petrol tested but Her Majesties Revenue and Customs (HMRC) do random road side checking for "red" diesel on a regular basis, red diesel is used for agricultural vehicles only and is exempt from fuel duty (tax).

Here in the U.S., thanks to our current environmental regulations, you can be fined up to $10,000.00 U.S. for using any leaded fuel on any public roads. If the Feds, State, county or city authorities catch you using the red diesel fuel, which is exempt from road taxes here also , on the roads they can fine and or put you in jail for that also Freedom my rear

I have never heard that about leaded or heard anybody EVER get their gasoline tested for lead. Glad I don't live in your state.
