BAD DAY AT THE RACE TRACK IN SACRAMENTO
#1
well guys today was the first time i brought MARIA to the drag strip here in sacramento california. i felt good about my current 466 built doing ok on street tires, but boy did i prove myself wrong within a few runs at the track.

my first run, i got foot happy and spun out half way down the track in 1st, 2nd, and partial of 3rd and again at 4th. i was a slow high 15's. (boy did i roast them tires thru all of 3) and my MSD tach adapter is above to get ripped out and destroyed. when i needed it most, it is just floating around and not really teling me my RPM. most of the time it works but at times it will flounder around and float.

on my 2nd run, i went up against my friends foose mustang and did a slightly better low 15's. this time getting it to hook up somewhat in the 2nd and 3rd gear going about 100mph at the end. still can't reading the rpms right and i am redlining every single gear and it doesn't help i missed third gear.

on my 3rd run my friends suggested i take off in 2nd gear. and at the time i was laughed at by all of my friends because my car stalled on green. again, i'm redlining all my gear and there are times when when i shift into the next gear it won't' rev until i left off the gas.

at this time i am frustrated with the traction issue and the issue with it not wanting to rev or can't read the rpms.

i believe drag radials or full slicks (extra rear tires) will be in my future to help out with most of the problems. i believe it time i go back to my roots and ask the 460 gods for help on my 466 set up.

Hang in there! Sounds like you could have some fuel supply issues also.

A FRIEND WHO WAS RUNNING A SIMILAR SETUP HAD YOUR STUMBLE PROBLEM, AND AS FAST E SAID FUEL DELIVERY.. A SET OF JET EXTENTIONS AND A NOTCHED FLOAT CURED THE PROBLEM. HE LAUNCHED AND HIT THE GEARS SO HARD THAT IT THRU THE FUEL TO THE BACK OF THE BOWL IN THE SECONDARIES WHICH OF COURSE MEANS NO FUEL.

Olie, a set of drag radials will help a lot. I had the same traction problem. I put DOT tire on and now the car launches hard with no tire spin.

On my car. The sight glass broke so I'm guessing with float level. I guess can be having fuel problems. I have a summit 130gph pump and when I drive on the street it doesn't seem like I have the same issue on alot of these open roads where I can nail 0-60 legally really hard.

I guess the next step would be to figure out the maximum backspacing with a factory swaybar n get my wheels widen n get some drag radials. I also need to get a reliable rpm ready n possibly a shift light!!!

I never have any problems at all losing traction in my 73 Vert. Of course it is a 6 banger! Dodgy

i might be looking into dropping gear numerically to 3.25 to make better use of each gear but better if it was a definate lock of a detroit locker!

Olie, X3 on the jet extensions, especially if you do go to drag radials. Fill the fuel tank before you get to the track. If fuel sloshes away from the pick-up it will starve for fuel too.

Make sure your driveshaft, transmission and clutch are in good shape. When you start getting the car to hook you will find the weak links in the drivetrain (we race stick shift cars). Absolutely, by all means install a driveshaft safety loop if you do not have one.

last night i am replacing some really old ignition parts. and i did find my mechanical advance on the dizzy isn't working as it leaks in the diapraham. and i am figuring out i need to recurve my duaspark dizzy and that explains why my total advance is only 25 instead of 35 at 3000rpms. so i got some dizzy work to do.

on the jet extension part, i don't know how this is coming about but i guess it could. i don't have any problems when i'm messing around these open roads here. i am however needing to run a hard fuel ine from the pump to the filter so i don't have more than 12 inches of rubber hoses so i can go out the street grudge drag matches next month. so, jet extension is on my list.

right now, i am gathering on a new 6AL for a rev limiter insead of my 6A, traction bars, recurved dizzy, and jet extensions.

my clutch, transmission, and driveshaft and brand new. i had to get everything new when i went over from a C6 to a TKO600. i should be good here, on a driveshaft safety loop. i had one installed prior the swap but for some reason i can't put it back in when i'm laying down on the ground. however, my h pipe is so big and far back, i'm sure if for some unforeseen reason the driveshaft busted and dropped, my h-pipe will catch it. i will however try to get her back up there.

Drag radials should help a lot. I have some good traction bars on mine and it still has zero traction with the BF Goodrich Radial T/As. Those are decent street tires but absolutely suck at the track. My car has a c-6 and 3.70 gears and if I lay into it to hard, it just roasts up the tires and I am red-lined, in 3 gear in about 80 feet. When it goes back on the road next time, it will be making more power so there is no way to go to the track on street tires.

I agree with the jet extentions also. You might even want to run a bigger fuel line to make sure you get enough gas up to the carb. The standard fuel line may be small and might even be kinked or dented somewhere.
