Hey Dave,

He always ran conventional 20/50 VR1 in the past and this year he switched to 20/50 VR1 Synthetic. It's a 4x4 pulling truck on racing gas he is always at about 180 water temps before a run.

Main clearances were .0035" - .004" on the mains and .0026" to .0028" on the rods.

He is going to a bigger pressure section on the dry sump pump as we feel the 1.450" spur gear might be on the small side, but when he bought it Nutter assured him it was plenty.

Thanks,
Butch Smith

Nothing sounds way out of line, might try to stay slightly looser on the rods not a bunch but stay on the high side of a little more

Here is the main gallery on the Eliminator block, it's from March 2015 block # 474. A 23/64" drill will go, a 3/8" will not.

The 1.450" spur gear should be enough. At least it is with the SCP pumps. I'd up the pressure to 70-75 PSI with that kind of RPM. At 8,000 or more .003" 0n the rods would be better.

What rods does the engine have?

Hey Lem,

He was running Molnar H beams with ARP 2000 bolts. It's a 4.600" stroke Molnar crank and 4.700" bores. I had originally posted he was running the oil pump at 56% but he told me it was actually 62%.

Appreciate the help guys!

Thanks,
Butch Smith

At that RPM the pump speed may be more than it needs to be with the 62%. Call the pump guy to find out.

Stamping on my A460 block is 4K3811 not sure if that means it was manufactured in 2011? Also the lifter gallery is just under 7/16".

4 is the year, K is the month and 3811 is the block number.

That block has been around a while. The block I have in stock is #6080.

So it was made in November of 2004 then? I bought this one used from a guy who ran it for several years in an alcohol drag car so makes sense.

The casting date is cast in the lifter valley. The stamped 4K is when the block was machined and sonic checked.

It'd be October. Ford doesn't use I .
