what do they have?

Same as motorcycles, its plated. If you guys arent using oil and water heaters you are crazy.

quit throwing tiny tidbits of shit we would really like to know. You're in the state-of-the art stuff like no one else here may be, even if it's 3 or 4 year old stuff, most here have never even dreamed of it. Please tell us about water and oil heaters and their advantages. Don't be a tease!

Hell, even I know about water and oil heaters. You want your fluids at temp for wear and power advantages. Ever gone to a local dirt track and hear all the engines running before they start racing? They're warming everything up.

Grape, what kind of main bearing clearances are they running in the cup/Indy levels now?

I was thinking this thread was going to be about building a 5.0 motor in Qatar during a sandstorm.

I am disappoint.

With a methanol car its hard to get temperature in stuff, consistency of oil and water temp is why i would use heaters between rounds if i was bracket racing.


Honda and chevy guys wont tell me much due to my business but, around .002" ish is where all those clearances are. They were using 0-30 mobil 1 purpose built racing oil at indy this past weekend.

a 180 thermostat and leanout at idle works ok

An electric fan we can turn off, electric water pump thats reverse flow the block pump so when it's running, it counters some of the block pump flow. we mainly run it between rounds in the hot summer with the fan.

what oil pressure they run, roller cam bearings? still using casidum coatings on stuff, coated bearings any good, what ring package, anything else you care to write about is great.

This is why I loved my FAST system while running methanol. Up until 160 degrees water temp it ran lean and built up heat pretty quick, then it ran around normal until 195, then it was set up to run rich to cool it down some.

I staged with water at 170, but always made sure it had a full heat cycle to warm up oil, and that huge heat sink sitting on the back of the block had its temps also. Trans brake helps there a ton.

I just hated the damn belt drive fuel pump.

Indycar stuff id have to look at pressures, stockcar stuff is typical except for the old plate stuff was 40 lbs at 7500 all day long. Stockcar guys are coating everything and they are all shrinking everything. XA rings are pretty common, if they use a 3 ring stack at all. Indycar stuff cams ride in cam journals like a bike engine, stockcars are all needle stuff.

.002 is where I was planning on setting mine. More specifically,in the .0021-.0022 range.

[Blackpony]

typically the rule of thumb is .001 clearance per 1 inch of journal diameter.

one man's opinion

If you do go that route don't take your intake to your buddy Dennis. Took him a intake and a set of injector rails to get them machined and he looked at me like I was asking him to build me a part for the international space station. I mentioned it said on his site he does that and he said he didn't even know he had a website. I personally wouldnt let that guy gap the plug for my lawnmower.

Dennis has had a race engine shop since 1968. He built it from scratch. He has a million dollars + in equipment. Dennis's father ground crankshafts and did flathead valvejobs with the engine and crank in the car for car lots throughout Dallas in the 40's through the early 60's ( Jimmys portable crankshaft grinding service ). Dennis had a machinest, Lonny, that did his web page about 1996. Lonny did a lot of the things listed on the web page, not Dennis. Drilling for injectors was one of the things Lonny did and Dennis sends him work all the time. Dennis has a head guy, a engine builder, a teardown guy. Dennis's wife, Sharon, grinds the cranks. Dennis spends a week every year at the PRI show. He buys somekind of new machine from the PRI show most years. Dennis runs the dyno. He custom built air starters on the rollers to allow starting sprint cars on the dyno. I'm sorry you had a bad experence with Dennis on your intake. Tens of thousands of others are happy with his work.

Dennis is a good guy and he is super sharp. You have to understand that he turns jobs out that make him over $100/hr. if he stopped his normal routine to spend 4-6 hours on your intake manifold, you would have cried at the $500-600 làbor bill.

Dennis got a bad rep around for just that in the mid-late 90's, and was turning out some work that wasnt great. He was more expensive than most others out there to do a "stock" rebuild, and people expected to get what they paid for, and werent getting it. Plus, Dennis was a bit of a dick when you werent spending 10k with him.

That has turned around, I used them to balance foxbody flywheels to 28oz for my 69 and some others who wanted the same. They did a good job, and were done when promised. Afterwards I found Arlington Machine was about half the price.

Dennis did the 347 in my old F100. I drove that motor pretty hard for the few years I had it and never had a single problem with it once.
