I'm going to use maxima 727 at 20:1 mix and jet for it. That's more oil/ lubricate over the 40:1 super maxima I was using.

best get a 44 gallon drum bill, at your throttle openings, you'll be out of gas in a flash

so the manual is wrong when it specs 25:1 with 70s-80s technology oil?

Maxima spec sheet recommends 20:1 ratio for road racing and drag racing 2T I'm thinking for heavy duty use.

road racing yes...didnt you make it a point several times saying you are putting around with your grandkids? you have to match it to your rpm. in this thread, trying set a top speed then more oil is appropriate...are you going to abuse your swedes that hard? road racing??

Local company which blends specialised synthetic oils for a variety of purposes.
At 20to1 and 25to1 there is plenty drool and splattering.
Normal riding with 32to1 no splooge.

The ratio debate will rage forever and each to his own.
I just know from experience what works best on my huskies for a variety of applications ranging from clambering mountains and ravines thru vmx to flattracking to roadracing and topend runs.

Assembled , pressure tested.
Some changes to previous spec.Testing in May

Sweet engine, awesome siloete behind it.

Just look at how tall the top end is on that motor. It's no wonder they vibrate.

Is that a spacer behind intake?
What's under the car cover, GT or Gt-40?

It won't be a GT40 - I don't think he's that rich.

Those 83 500s were a rough ride. My Xc vibrated like a damn jackhammer compared to my lc 500

due to a much heavier piston

82 to 87 use the same pistons

Mossbarger reedblock.
Mahle piston on lc had larger cutaway across transfer port area thus a tad ljghter. The lc crank webs had a slightly deeper cutaway to compensate for balancing.
Biggest vibration factor is runout between crankpins.

Under the cover is an animal of a different topic.

just saw one of the only 3 original gt 40 open top 289 ci cars left in the world ( 1 is a dubious claim) at the historics. they took 5 opens and 5 closed cars in the first attempt at Le Mans. the 5 opens were slower and colder so they ran the closed cars, using the open tops at the mille miglia later that year. this car turned up as a wreck after being stored for many years. the owner had no idea what the significance of the car was. he does now. it was quick and I just assumed 6 litre but it was only a small block. very nice...

Well Rowan looks like i was right.

What I was meaning is that it won't be an original GT40.

Many years ago I was told by the (then) Husky importer for NZ to use air cooled pistons in my auto if I ever needed to replace one. He said the AC items didn't have cut-outs on either side so the gudgeon pin went all the way across the piston and had mode 'bearing surface'. Sure enough mine (LC) elongated the pin holes after a couple of years but the replacement AC item went for another couple of decades.
Did the 500 have two similar designs over the years?

Apparently , so I read , there were only seven Ford GT 40's made and one is in Melbourne.

More than that, there is 2 real 1s here in my home town.
1 is Dan Gurney's old car with bubble in the top part of the door for his head.
