Chris - I see you are on the other side of the sound from me, small world.
MUST...HAVE...ALL POSSIBLE INFORMATION!I am running EFI 6 packs on my Cuda (416) and Challenger (440)
Once I had the epiphany of how to use blocking the bleed with my finger to determine rich/lean status of the outboard mixture screws, that allowed for much better 6bbl tuning. I've invested about $1k in parts and labor with Promax for my 3 Holley 2bbl carbs. Other than a turbo spooling up, there's nothing else that I have experienced that compares with the rush of the outboard carbs opening on a hopped up, well tuned big block Wedge!I grew up running 440 6 packs and always loved them
That would be the case only if you drove a big cube gas hog. 120 miles divided by 16 = 7.5 mpg. Should not be to hard to accomplish. In fact I believe I have done better on some 60 mile runs at 2 miles per minute and less.Look at the amount of fuel you need to carry for something like the Silver State Challenge. 90-120 Miles, many of the cars run out of fuel.
If your getting around 4 MPH (higher power/speeds might get less MPG?), you need 25-30 gallons of fuel. At 6.3 lbs/gallon that is around 160 - 190 pounds of fuel.
You would want to keep the fuel from sloshing as the weight transfer of the fuel can spin the car out around corners with the stock tank location.
Re-locating the fuel tank (if possible) ahead of the rear wheels, about where the back seat would be, would help handling.
That is a consideration for sure. The SSCC in September is 90 miles one way. The NORC in May is 60 miles two ways, there and back with a fueilng truck at the other end. There are a couple retired NASCARs that make the run and need the fuel on the longer two way race.Look at the amount of fuel you need to carry for something like the Silver State Challenge. 90-120 Miles, many of the cars run out of fuel.

Absolutely! There are some amazing cars and some everyday cars that run in the Silver State Challenge. Lots of newer Vettes, Challengers, BMWs, Porsches, old muscle cars, Lambos etc... I've heard of people renting a car, installing a fire extinguisher and running in the 110 class!I've got a friend that raced in the silver state classic with his 66 mustang gt350r clone. If I recall you have to start at slower speeds and work your way up to faster speeds. Seems like he did 110 the first year then 140 the next. A crazy variety of cars would run and the classics usually get lots of attention. He had a 25 gallon fuel cell. I just happen to visited him in San Diego shortly after the race when he had a date on wheel dyno. 385 hp at the wheels which was decent for his 342. He blew it up running lean going around a road course and spent a ton of money on a 550 hp small block. The speed at silver lake seems to be addictive for sure. Pretty unique place.
Is that an average speed limit or an any time top limit?Absolutely! There are some amazing cars and some everyday cars that run in the Silver State Challenge.

Yes, depending on your racing experience, you start off in the touring class with basic safety equipment. That is 95-110 MPH if I'm not mistaken, then you can run the next level with the higher speeds requiring increased safety equipment. With that said, I have my car in the fab shop installing the roll cage for the Unlimited class. (Once I get to that level)
Looks like it would take more than a few years to get to the Unlimited class without prior approved racing experience.Absolutely!

The class you race in is the average speed for the 90 miles. The tecnical speed it the speed in MPH that you are not allowed to exceed or ricks getting disqualified. There is also a minimum speed which receives the same DQ if you go below it.Is that an average speed limit or an any time top limit?
There are a number of websites where different divers have installed GoPro camera. Check them out!Website gives no real run route other than Ely and rte 318. I an guessing it really starts at Lund and ends at Hiko. Would this be a correct assumption for anyone wanting to take a leisure run just to see what the road is like.
Hi Mike,Hi Chris
For those that don't know me, I last ran the 135mph class with a 383, 833OD, 3.23. gear 72 Charger. I hope to get back into it soon.
To answer the fuel question, I have a 22 gallon cell and it is more than enough to go the 90 mile race plus driving the 45 miles or so getting to the start line and then the gas station in Ash Springs (end of the run). When I ran with a 440 in the 120mph class I was getting 9mpg!
Lotsa, lotsa fun. More people need to try it!
